British rifle-making company RPA Precision Ltd (now RPA International Ltd) originally built indigenous target rifles, and entered "tactical rifle" market in 2001 with new 7.62mm "Range master" sniper rifle, based on proprietary RPA Quadlock® action, used in their match rifles. The 7.62mm "Range master" rifle was soon supplemented with long range anti-personnel .338Lapua version in 2004, and long range / anti-material .50 caliber version in 2005. According to the manufacturer, RPA "Range master"rifles are in active use with a significant number of police and security organizations across the world. With proper ammunition, all RPA "Range master" rifles are capable of constant sub-MOA accuracy.
RPA "Range master" sniper rifles are built around proprietary Quadlock® action,which features manually operated rotary bolt with four frontal radial lugs. Barrels are fluted for better heat dissipation, and threaded to accept a muzzle brake or silencer. Triggers are of two-stage type,fully adjustable, with ambidextrous manual safety conveniently located just above the trigger. Rifles are fed using detachable box magazines holding five rounds. Stock is of composite (aluminum+ polymer) design, with side-folding butt which is adjustable for length of pull. Unusual features of the RPA stock design are bolt channel, which also serves as the stock comb / cheek rest, and the fact that in emergency situations rifle can be fired with butt folded. RPA "Range master"sniper rifles are sold without any iron sights, and equipped with standardPicatinny rail on the receiver which can accept a wide variety of day or night sighting equipment. Two additional lengths of Pica tinny rail are installed on the for end. Other accessories include folding adjustable bi pod and adjustable mono pod, built into the butt stock.

The M90 rifle was developed in 1990 by the American company Barrett Firearms co for those customers who want or needed a .50 caliber rifle but prefer a bolt action instead of the semi-automatic design, offered in the Barrett's' flagship model, M82A1. The new rifle also was lighter and some30 centimeters (12") shorter than the M82A1, and also about 30% less expensive (comparing current MSRP of M82A1 and M95). After initial experience with this rifle it was replaced in production in 1995 by the slightly upgradedM95 model rifle, which is still in production. It is used by civilian long range competition shooters across the world, and by various military and law enforcement forces. It is not so popular across the government users, unlike the Barrett M82A1. In the year 1999 the M95 won the US Army competition for XM-107.50 caliber sniper rifle, and was subsequently bought by US Army in small number for further research and testing. The Barrett website also announces that M95rifle is used for military and law enforcement applications in at least 15 other countries. Like the M82A1, the M95 primary application are anti-materiel and counter-sniper operations and explosive ordnance disposal.
M90 is a manually operated, bolt action rifle of bull pup layout. The rotating bolt has three massive lugs that locks directly into the barrel. The long fluted barrel is similar to one used in M82A1 rifle and has the same two chambers reactive muzzle brake. The receiver is made from stamped sheet steel and consists of two parts(upper and lower), connected by the push-pins. The detachable box magazine is shallower than one found on M82A1 rifles and holds only 5 rounds. The pistol handle ant the trigger are located just ahead of the magazine, the butt pad is attached directly to the receiver. M90 has no open iron sights, but features as cope mount on the top of the receiver. It is most commonly fitted with 10XLeupold M series telescope sights. M90 does not intended to be fired from the shoulder, and it has integral folding bi pod mounted on the front end of the lower receiver.
The M95 is an improved version of the M90. It featured pistol handle and the trigger unit moved forward for 1 inch (25 mm) for better clearance between the magazine and the pistol grip, and thus more comfortable handling and shooting. The bolt handle is slightly redesigned and bent down and to the rear. The barrel chamber is chrome plated for better extraction and corrosion resistance. There are also some minor improvements in the trigger /firing pin mechanism.

Caliber: 7.62 x 51mm NATO (.308 Win)
Action: Semi-automatic, roller-delayed blow back
Barrel: 650 mm
Overall length: 1208 mm
Weight: 8.10 kg with scope and no magazine
Magazine: 5 or 20 round detachable box
Scope: Hendsoldt 6x42, 6 settings from 100 to 600 meters
Expected accuracy: Sub-1MOA with match grade ammunition

The PSG-1 sniper system (PrazisionsSchutzenGewehr, or "high-precision marksman's rifle"in English) had been developed by the German company Heckler - Koch by the mid-1980s as an ultimate police and counter-terror weapon. Some German elite law-enforcement groups, like GSG or KSK-9, participate in this development, and since its introduction the PSG-1 had been adopted by various police forces in Europe and Americas. It is way too heavy and somewhat too gentle for military use, so it never seen any military use. Instead, HK developed two more sniper weapons. The first, that actually preceded the PSG-1, was the G3-SG1, an accurizedand scope-fitted version of the basic G3 automatic rifle for German Army. And Ianthe mid-1980s HK also developed a derivative of the PSG-1, called MSG-90, for export military sales. The PSG-1 is still offered by the HK, and is one of the most expensive factory-made sniper rifles on the market, hitting the $10.000price tag in the basic package.
Technically, the PSG-1 is no more than a heavily modified G3 rifle. It features the same roller-delayed blow back action, derived from earlier CETME rifles, and the same stamped steel receiver with separate detachable trigger unit. The heavy barrel is precisely made by the cold hammer forging process with polygonal rifling for improved accuracy and longer life. Special trigger unit features semi-automatic only hammer group and the adjustable trigger with trigger pull of about 1.5 kg (3 lbs). The ergonomically shaped pistol grip features an adjustable palm stop. Plastic butt stock is also adjustable for height and for length of pull. Another non-typical feature of the PSG-1 is the "silent bolt closing device", actually similar to the forward assist, found on M16rifles. This is apparently to be used in situations where a complete silence must be maintained until the shot is fired. The devise is no more that apushbutton, located just behind the ejection port, and linked to the bolt carrier by the ratchet-like device. The rifle is fed using standard 20-rounds G3magazines or special 5-rounds magazines. There's no open (iron) sights on thePSG-1. Instead, it is fitted with the Hendsoldt 6X42 fixed power telescope sight with illuminated reticle. The scope has built-in range adjuster that works in ranges from 100 to 60 meters, so 600 meters is considered the maximum effective range. Most strangely, the PSG-1 had no integral bi pod. Instead, it is often used with the separate rest, mounted on the compact tripod.

The entire idea behind the CheyTac LRRS (Long Range Rifle System) is to provide long range soft targetinterdiction (read: anti-personnel sniper) rifle package, with maximum effective range, but relatively compact and light. To achieve this goal, the professor John D. Taylor designed the .408CheyTac cartridge. Being mid-way in size between the mighty .50BMG and already established long-range favorite .338Lapua, the .408 features a streamlined bullet with advanced patented design. This design allows the standard 419 grain (27.15gram) bullet to retain its supersonic velocity at the ranges beyond 2000 meters (2200 yards). At the ranges beyond 700 meters the .408 bullet has more energy than the standard .50BMG ball bullet. The .408 cartridge also is lighter than.50BMG cartridge by about 1/3, and generates less recoil. 
The original CheyTacIntervention M100 rifle is based on the Wind runner .50 caliber take down rifle fromEDM Arms. Current Intervention M200 sniper rifles still are based on Windrunnerdesign, but with several modifications. The Long Range Rifle System also includes CheyTac tactical computer (commercial PDA with Cheetah ballistic software), Night force NXS 5.5-22X scope, and Kestrel 4000 wind/temperature/atmospheric pressure sensors, linked to the PDA. The Tactical Computer with sensors andinternal ballistic database provides all necessary data for long range fire.CheyTac papers state that the entire System is capable to deliver sub-Accuracy at the ranges of up to 2500 yards (2270 meters).
The Intervention M200is a manually operated, rotating bolt rifle. The retractable buttstock allowsfor adjustment of the length of pull, and can be fully collapsed for storage andtransportation. The barrel can be quickly removed for replacement, or storage and transportation. The butt contains integral real monopod, which is hinged,and can be folded up when not in use. The heavy, fluted barrel is free floated,and its rear part is enclosed by tubular shroud, which serves as a mount for integral folding bi pod and carrying handle. Barrel is provided with effective muzzle brake, which can be replaced with OPS INC suppressor (silencer). M200rifle is fed using detachable single stack magazines, which hold 5 rounds. Top of receiver is fitted with permanent Mil Std Pica tinny rail. Standard scope is Nightforce NXS 5.5-22X, which can be upgraded with AN/PVS-14 Night Vision module and AN/PEQ-2 IR laser. No iron sights are provided with M200 rifle.
CheyTacAssociates also offers a less expensive, non-take down single shot rifle in .408caliber, the Intervention M310. This bolt action rifle with adjustable polymer stock is suitable for long range sport shooting, as well as for police long range snipers.

F90 assault rifle, also known as EF88 (enhanced F88) is an evolution of the F88 assault rifle, which was adopted by Australian and New Zealand armed forces during late 1980s. The original F88 rifle is a licensed copy of the Austrian Steyr AUG rifle, and it was produced in Australia at Australian Defense Industries factory in Lithgow. Today this same factory is operated by the Thales Australia, which developed EF88 / F90 rifle as a next weapon for Australian army, as well as for export.
While internally and externally the F90 is still close to Steyr AUG, it has many distinctive upgrades and changes, developed by Thales to fulfill current and near-future requirements of Australian armed forces. The Thales F90 rifles were first displayed to the public in mid-2012, and initial production is scheduled for 2013.
The resulting weapon is said to be much more reliable and comfortable than original F88 / Steyr AUG rifle. It is also noticeably lighter: standard F90 with 50 cm / 20” barrel is about 0.5 kg / 1.1 lbs lighter than standard F88 rifle; with new 40mm underbarrel grenade launcher installed, resulting weapon is more than 1.6 kg / 3.5 lbs lighter than F88 rifle equipped with M203PI grenade launcher.
F90 / EF88 assault rifle is gas operated, selectively fired weapon of bullpup layout. It uses polymer housing with improved shape of buttstock (including the new buttpad and added comb for better cheek-weld). Gas operated, short-stroke, rotary bolt action is similar to that of original Steyr AUG, but the gas block is modified. Aluminum alloy receiver is also modified to improve reliability and reduce weight. Ejection ports and ejection covers also modified to ensure reliable extraction under all conditions.
Unlike all previous versions of the Steyr AUG, the F90 has non-removable barrels, cold-hammer forged and externally fluted. Standard F90 rifles are offered with 50 cm / 20” barrels; other versions include carbines with 40 cm / 16” barrel and CQB variants with 36 cm / 14.1” barrel. Other clearly visible changes include extended Mil-Std (Picatinny) rail at the top; bottom rail has replaced original folding forward grip of the Steyr AUG / F88. Third accessory rail is mounted on the right side of the weapon. Trigger guard is redesigned to accept new, specially designed 40mm Underbarrel Grenade Launcher. This lightweight add-on weapon can be quickly attached directly to the bottom rail of the host rifle, and then easily removed when not required. Less visible changes include addition of the bolt hold-open device to facilitate faster reloads. F90 will feed from the same proprietary translucent magazines, made from polymer as the original Steyr AUG / F88 rifles, although optional STANAG-compatible version is said to be available in the near future. Basic sighting is provided by Trijicon ACOG optical sights with 1.5X or 3.5X magnification, although sights can be easily changed, thanks to MilStd mounts.

The FN FAL (Fusil Automatique Leger - Light Automatic Rifle) is one of the most famous and widespread military rifle designs of the XX century. Developed by the Belgian Fabrique Nationale company, it was used by some 70 or even more countries, and was manufactured in at least 10 countries. At the present time the service days of the most FAL rifles are gone, but it is still used in some parts of the world. The history of the FAL began circa 1946, when FN began to develop a new assault rifle, chambered for German 7.92x33mm Kurz intermediate cartridge. The design team was lead by Dieudonne Saive, who at the same time worked at the battle rifle, chambered for "old time" full-power rifle cartridges, which latter became the SAFN-49. It is not thus surprising that both rifles are mechanically quite similar. In the late 1940s Belgians joined the Britain and selected a British .280 (7x43mm) intermediate cartridge for further development. In 1950 both Belgian FAL prototype and British EM-2 bullpup assault rifles were tested by US Army. The FAL prototype greatly impressed the Americans, but the idea of the intermediate cartridge was at that moment incomprehensible for them, and USA insisted on adoption of their full-power T65 cartridge as a NATO standard in 1953-1954. Preparing for this adoption, FN redesigned their rifle for the newest T65 / 7.62x51mm NATO ammunition, and first 7.62mm FALs were ready in 1953. Belgium was not the the first country to adopt their own rifle in 1956. Probably the first one was a Canada, adopting their slightly modified version of FAL as C1 in 1955. Canadians set to produce C1 and heavy barreled C2 squad automatic rifles at their own Canadian Arsenal factory. Britain followed the suit and adopted the FAL in 1957 as an L1A1 SLR (Self-loading rifle), often issued with 4X SUIT optical scopes. Britain also produced their own rifles at the RSAF Enfield and BSA factories. Austria adopted the FAL in 1958 as a Stg.58 and manufactured their rifles at Steyr arms factory. Various versions of FAL were also adopted by the Brazil, Turkey, Australia, Israel, South Africa, West Germany and many other countries. The success of the FAL could be even greater if Belgians would sell the license to W.Germany, which really liked to produce the FAL as a G1 rifle, but Belgians rejected the request. Germany purchased the license for Spanish CETME rifle and as a result of this H&K G3 rifle became probably the most notable rival to FAL.

During the time, FAL was built in numerous versions, with different furniture, sights, barrel lengths etc. There are, however, four basic configurations of FAL rifle: FAL 50.00, or simply FAL, with fixed buttstock and standard barrel; FAL 50.63 or FAL "Para", with folding skeleton butt and short barrel; FAL 50.64 with folding skeleton butt of "Para" model and standard length barrel; and the FAL 50.41, also known as FAL Hbar or FALO - a heavy barreled model which was intended primary as a light support weapon. There are also two major patterns of FALs around the globe: "metric" and "inch" FALs. As the names implied, these were built in countries with metric or imperial (inch) measure systems. These patterns are slightly different in some dimensions, and magazines of metric and inch pattern sometimes could not be interchanged. Most "inch" pattern FALs were made in British Commonwealth countries (UK, Canada, Australia) and have had folding cocking handles and were mostly limited to semi-automatic fire only (except for Hbar versions like C2). Most "metric" pattern rifles had non-folding cocking handles and may or may not have select-fire capability, but as with other light select-fire weapons chambered for 7.62x51mm NATO round, the controllability of the full auto fire is disappointing and shots spread in burst is extremely wide. But, regardless of this, the FAL is one of the best so known "battle rifles", reliable, comfortable and accurate. It is somewhat sensitive to fine sand and dust but otherwise is a great weapon.

The only countries still producing the FAL rifles until the present time are the Brazil and, most surprisingly, the USA. Brazil adopted the FAL under the name LAR and manufactured it at the IMBEL facilities. The USA produced a small amount of FALs as the T-48 at H&R factory in early 1950s for Army trials, but at the present time a number of private US Companies is manufacturing various versions of FAL rifles using either surplus parts kits or newly manufactured parts. Most of these rifles are limited to semi-auto only and are available for civilian users. Probably most notable US manufacturer of FAL modifications is the DS Arms company, which produced its rifles under the name of DSA-58.

The FN FAL is a gas operated, selective fire or semi-automatic only, magazine fed rifle. It uses short piston stroke gas system with gas piston located above the barrel and having its own return spring. After the shot is fired, the gas piston makes a quick tap to the bolt carrier and then returns back, and the rest of the reloading cycle is commenced by the inertia of bolt group. The gas system is fitted with gas regulator so it could be easily adjusted for various environment conditions, or cut off completely so rifle grenades could be safely launched from the barrel. The locking system uses bolt carrier with separate bolt that locks the barrel by tipping its rear part into the recess in the receiver floor. The receivers initially were machined from the forged steel blocks, and in 1973 FN began to manufacture investment cast receivers to decrease production costs. Many manufactures, however, stuck to the machined receivers. The trigger housing with pistol grip is hinged to the receiver behind the magazine well and could be swung down to open action for maintenance and disassembly. The recoil spring is housed in the butt of the rifle in fixed butt configurations or in the receiver cover in folding butt configurations, so the folding butt versions require a slightly different bolt carrier, receiver cover and a recoils spring. The cocking handle is located at the left side of the receiver and does not move when gun is fired. It could be folding or non-folding, depending on the country of origin. The safety - fire selector switch is located at the trigger housing, above the triggerguard. It can have two (on semi-automatic) or three (on select-fire rifles) positions. The firing mechanism is hammer fired and use single sear for both semi-automatic or full automatic fire. Barrel is equipped with long flash hider which also serves as a rifle grenade launcher. Design of flash hider may differs slightly from country to country. The furniture of the FAL also can differ - it could be made from wood, plastic of various colors or metal (folding buttstocks, metallic handguards on some models). Some models, such as Austrian Stg.58 or Brazilian LAR were fitted with light bipods as a standard. Almost all heavy barrel versions also were fitted with bipods of various design. Sights usually are of hooded post front and adjustable diopter rear types, but can differ in details and markings. Almost all FAL rifles are equipped with sling swivels and most of rifles are fitted with bayonet lugs.

During the late 1980s and early 1990sfamous Belgian company FN Herstal began the search for its next entry into the assault rifle world. The aim this time was to produce a modern, modular weapon, and this ultimately resulted in the FN F2000 rifle, which was first displayed in public in 2001. The F2000 offers all of the most popular features of the modern assault rifle, such as a compact bullpup layout, completely ambidextrous handling, and a modular design with plenty of options and add-ons already available, which allow the rifle to be “tailored” for any particular mission or tactical situation. For example, for peacekeeping operations F2000 could be fitted with less-lethal M303 underbarrel module, which fires tear gas or marker projectiles using pre-compressed air. On the other hand, the F2000 could be fitted with various 40 mm FN EGLM grenade launchers and a proprietary computerized fire control system, instead of the standard low-magnification optical sights.So far FN F2000 rifle found only few buyers, including Armed forces of Sloveniaand Belgian Special operations forces. Nevertheless, it is one of most promising assault rifles on the market.
 Quite recently FN also introduced a civilian version of F2000, known as FS2000.It has a somewhat longer barrel and is limited to semi-automatic fire. Otherwise it is the same excellent weapon, with great ergonomics and 100% ambidexterity.
The F2000 rifle is a gas operated, rotating bolt, selective-fire weapon, featuring a polymer stock with a bull-pup layout. Itutilizes a short-stroke gas piston and a 7-lug rotating bolt which locks into the barrel extension. The unique feature of the F2000 rifle is its patented front ejection system: the spent cases, extracted from the chamber, travel from the rear part of the gun to the ejection port near the muzzle via a special ejection tube and fall out of the gun at the safe distance from the shooters' face. This is achieved using a special swinging guide, which enters the way of the closing bolt, and directs the spent case, which is held on the bolt face, to the ejection tube, while, at the same time, lower lugs of the bolt are stripping a fresh cartridge from the magazine. The cocking handle is mounted well forward on the left hand side, just above the fore grip, and it can easily be operated with the right hand when the gun is held left-handed. The selector switch is mounted at the bottom of the trigger guard. All of these features combine to make the F2000 the first genuinely ambidextrous bullpup, able to be used with equal ease by right and left handed shooters without requiring any adjustments. In its standard configuration, the F2000 is perfectly balanced around the pistol grip.
 The stock has built-in standard rails on the top of the weapon (for different sights and scopes etc) and a mounting point ahead of trigger guard, where additional modules may be installed (such as grenade launchers, non-lethal modules etc). In the basic configuration, the upper rail mount is fitted with a 1.6X magnification optical sight, and the lower mounting point is covered by a removable handguard. At the current time, the F2000 rifle may be upgraded, depending on the mission, with FN's 40 mm low-velocity grenade launcher (on the lower mount, instead of the handguard), or with M303 non-lethal module; other options are handguards with built-in laser pointers or flashlights. The standard low-magnification combat scope, which has a back-up open sights on its top cover, may be replaced by any other scope onPiatiny-style mount, or with FN's proprietary computerized fire control module with laser rangefinder, for both the rifle and 40 mm grenade launcher.

The US Special Operations Command(US SOCOM) issued a solicitation for the procurement of SOF CombatAssault Rifles (SCAR)on October 15th, 2003. This solicitation requested a new combat rifle,specially tailored for the current and proposed future needs of the US Special Forces,which are somewhat different from latest generic US Army requirements,which are being fulfilled by the newest Heckler-KochXM8 assaultrifle. The key difference in basic requirements between XM8 and SCAR is that, while XM8 is a single-caliber weapon system, tailored for5.56x45mm NATO ammunition, the SCAR should be available in various different calibers.Initial SOF requirements included two basic versions of SCAR system - the SCARLight(SCAR-L), available in 5.56mm NATO, and the SCAR heavy (SCAR-H), which should be initially available in significantly more powerful 7.62x51 NATO chambering, andshould be easily adaptable in the field to other chamberings. These other chamberings initially include the well-spread 7.62x39 M43 ammunition oftheSoviet / Russian origins, and probably some others (like the proposed 6.8x43 Remington SPC cartridge, especially developed for US Special Forces).The keyidea of SCAR rifle system is that it will provide the Special Forces operators with wide variety of options, from short-barreled 5.56mm SCAR-L CQC variation,tailored for urban close combat, and up to long range 7.62x51 SCAR-HSnipervariant, as well as 7.62x39 SCAR-H, which will accept "battlefield pickup" AK-47/AKM magazines with 7.62 M43 ammunition, available during the operations behind the enemy lines.Both SCAR-Land SCAR-H shall be initially available in three versions, Standard(S), Close Quarters Combat (CQC) and Sniper Variant(SV; now it is dubbed Long Barrel - LB). All these variants, regardless the caliber and exact configuration, willprovide the operator with the same controls layout, same handling and maintenance procedures, and same optional equipment, such as sights,scopes, andother current and future attachments.
Late in 2004 USSOCOM announced, that the winner for the initial SCAR contracts is the FN USA, an US-based subsidiary of the famous Belgian company Fabrique Nationale Herstal. prototype rifles were manufactured by FN Manufacturing Inc, US-based subsidiary to FN Herstal; This company will also handle series production of rifles. Starting mid-2005, first SCAR rifles went to end users in US Special Operation Forces. Since USSOCOM uses Navy-type "mark" designations, SCAR rifles were officially designated as 5.56mm Rifle Mark 16 (SCAR-L / Light) and 7.62mm Rifle Mark 17 (SCAR-H/ Heavy).It is believed that Mk.16 and Mk.17 rifles will gradually replace most rifle systems now in service with US SOCOM forces, such as M4 carbines, M16 rifles, M14 rifles and Mk. 25 sniper rifles.
As it turned out, FNSCAR rifles are notbased on any previous weapons but designed from the scratch. In allvariants FN SCAR rifles feature gas operated,short stroke piston action with rotating bolt locking. Bolt has seven radial locking lugs that lock directly into the barrel extension.
  Receiver is made from two parts, upper and lower, connected with two cross-pins. Upper part is made from extruded aluminium, lower part is made from polymer. SCAR-L and SCAR-H use similar upper receivers that differ only in the size of ejection port. Other different parts include caliber-specific bolt, barrel, and lower receiver with integral magazine housing. Parts commonality between SCAR-L and SCAR-H is astonishing 90%. Barrelsare quick-detachable, and held in the upper receiver with two cross-bolts. Barrel change procedure requires minimum amount of tools, takes just several minutes and there is no need to adjust the headspace after the change.
  The trigger unit with ambidextrous safety-fire mode selectors witch allows for single shots and full automatic fire, with no provisions for limited-length bursts mode. The charging handle could be easily installed on either side of the weapon, so the upper receiver has respective cuts on both sides. Top of the upper receiver is covered by the full-length integral Picatinny rail (MIL-STD 1913); additional Picatinny rails are mounted on both sides and under the free-floating handguards. Side-folding polymer buttstock is adjustable for length of pull, and is shaped to provide positive cheekrest with adjustable cheek support. SCAR rifles are fitted with removable, adjustable iron sights, with folding diopter-type rear sight on the receiver rail, and folding frontsight onthe gas block. Any additional type of sighting equipment, necessary for current tasks, including telescope and night sights, can be installed using MIL-STD 1913 compatible mounts.
 Mk.16 SCAR-L rifle will use improved M16-type magazines, made of steel; Mk.17 SCAR-H will use proprietary 20-round magazines in 7.62x51 NATO chambering, or standard AK-type magazines in proposed 7.62x39 M43 chambering. Current prototypes of SCAR rifles do not have bayonet mounts,and, probably, will never have one.

The development of the new assault rifle, that should eventually replace in service the ageing M16A1, CAR-15 and IMI Galil assault rifles, began in Israel in the 1991. The new rifle was developed by the Israel Military Industries (IMI, now privatized as IWI - Israeli Weapons Industries Ltd) company, in close cooperation with the Israeli Defense Forces (IDF). This new rifle received the name of "Tavor" and the designation of TAR-21 (Tavor Assault Rifle, for 21st century). The new rifle first appeared on public in the1998,and it had been tested by the IDF during 1999-2002. Initial issue of Tavor rifles to IDF showed some teething problems, but by now the Tavoris already in widespread use by IDF, and it seems that many earlier problems are worked out. It is also in limited use with Special Operation forces of India and Georgia. 
In general,the TAR-21 represents the mainstream of the present assault rifle developments. It shares all the "modern"features, already tried and proved successful by previous designs, like the bullpup layout, polymer housing, optical sights as a prime sightinge quipment,modular design with several different configurations (from very short submachine gun and up to standard assault rifle and a para-sniper accurized rifle with heavy barrel). So far it seen not much real action, and it is hard to judge if it is really a success, and only time will show that. 
The IWI also developed and manufactures a civilian, semi-automatic only version of the Tavor rifle, which looks much like the Tavor Micro rifle but with longer barrel. This version has already been exported to several European countries and Canada.
The Tavor TAR-21 is a gas operated, selective fire, magazine fed assault rifle of bullpup configuration. It is available in several configurations,which differ in the barrel lengths and accessories. The basic configurationis the TAR-21 assault rifle with the 460mm (18.1 in) barrel. Next are the compact assault rifle, called CTAR-21, with the barrel 380 mm (15 in) long, and themicro assault rifle, with the barrel of only 330 mm (13 in) long,called MTAR-21. The latter rifle also featured a redesigned front part of the housing, with charging handle placed further back on receiver,for a more comfortable hold of the short weapon. Micro-Tavor also can be converted to 9mm pistol ammunition (9x19) with installation of the caliber conversion kit, which includes a new barrel, bolt group and a magazine adapter.
 TAR-21 utilizes a now-common long piston stroke, rotating bolt action, with the gas piston rigidly attached to the bolt carrier. Gas cylinder is located above the barrel and is completely enclosed by the gun housing. The rotating bolt is similar to one found in the M16 rifle and has seven lugs. The ejection ports are made on both sides of the weapon, and the right or the left side ejection can be selected by installing the bolt with the ejector mounted on the right or on the left,respectively(and, of cause, this change requires the gun to be partially disassembled). The bolt carrier rides on the single guide rod, with the return spring unit located above it, behind and inside the hollow gas piston rod. The charging handle is located at the front left side of the gun and does not reciprocate when gun is fired. The charging handle slots are cut on the both sides of the gun housing,so it can be installed on either side of the weapon, as required. The trigger unit is more or less conventional, with the ambidextrous fire mode selector /safety switch located above the pistol grip.
 The TAR-21 has no separate receiver. Instead, all parts are mounted within the high impact-resistant plastic housing, reinforced with steel inserts where appropriate. The access toall the internal parts is controlled by the hinged buttplate, which can be swungdown for internal inspection and disassembly.
 Early production TAR-21rifles had no open sights, but this has been fixed with introduction ofthe folded front and rear sights on current production models. Tavor rifles are fitted with the standard Picatinny-type accessory rail on the top of thegun. Early guns had Israeli-made ITLMARS as standard sight, which is a complicated and expensive reflex-type sight with the built-in laser pointer. For the night time operations the MARScould be complemented with the ITL Mini N/SEAS compact night vision device. Current manufacture Tavor rifles (except for Sniper version)are usually fitted with less expensive Meprolight red-dot sight. Snipervarsions usually are fitted with Trijicon ACOG optical sight with 4X magnification.
 The TAR-21 utilizes the STANAG-compliant, M16 type magazines, with standard capacity of 30 rounds.
  TAR-21 in its basic configuration can be fitted with 40mm M203 underbarrel grenade launcher.

 2001 concept of the AICW system

 2003 concept of the AICW system

 2005 testing prototype AICW VX3 weapon

Caliber: 5.56x45mm NATO + 40mm
 Action: Gas operated, rotating bolt + Metal Storm patented stacked-projectile caseless
 Overall length: 738 mm
 Barrel length: n/a
 Weigth: 6.48 kg unloaded, w/o sight; 7.85 kg loaded w/o sight (30 5.56mm + 3 40mm rounds); 9.9-9.9 kg loaded w. electronic sight
 Rate of fire: 650 rounds per minute (for 5.56mm barrel)
 Capacity: 30 rounds (5.56mm) magazine plus 3 40mm rounds in the G/L barrel

The AICW (Advanced Infantry Combat Weapon) is a joint development of the Australian DSTO (Government operated Defence Science and Technology Organisation), and private companies Metal Storm and Tenix Defence. This development has been carried out since the turn of 21st century, closely following the concept of the American XM29 OICW system. Overall, AICW represents the modular weapon system that combines the 5.56mm rifle/carbine copmponent as a host (basic) platform with 40mm multi-shot grenade launcher (G/L) module and multi-purpose electro-optical sighting system, which can be used to fire either rifle or G/L component, and also can provide recon data to external "consumers" such as tactical computers.
 The host rifle component of the AICW is the updated Australian-made F88 rifle, which is a license-built Steyr AUG.However, the basic F88 rifle has been extensively modified to accept other elements of the system - for example, receiver has been upgraded to receive the G/L module at the top, and the buttstock has been enlarged to accomodate G/L electronic fire contol module. Other changes include modification to the safety and trigger arrangements - AICW system has a single trigger for both weapon components (5.56 and 40mm), and a three position (safe - rifle - G/L) safety/selector switch at the side of the pistol grip.
 The most interesting part of the AICW weapon is the multi-shot Metal Storm 40mm grenade launcher, which looks like a single 40mm G/L barrel but contains three 40mm projectiles stacked one behind the another. These projectiles are launched using the electric ignition impulses, provided by the fire control module built into the buttstock of the host rifle. Since the muzzle velocity of these projectiles is slightly more than usual for 40mm handheld G/L (95m/s instead of 75m/s), host rifle incorporates the recoil reduction buffer, that allows the Metal Storm G/L barrel to recoil against the spring, decreasing the peak recoil impulse.
 The top of the receiver hosts the multi-role sights of various type and make. At the AICW VX3 live fire demonstartions that took place in the summer of 2005, AICW prototypes were displayed with ITL Viper multi-purpose rifle sight (that incorporates laser range-finder and digital compas), or with Vinghog Vingsight Fire Control System. At the present time (late 2005) AICW prototypes have not yet fired 40mm grenades with live warheads, nor incorporated an airburst facility. However, it is stated that it is possible to easily adapt most of the existing 40mm grenade warheads to the Metal Storm technology, including air-bursting grenades that are now in development in several countries.
At the present time AICW weapons are available only as the "3rd generation technology demonstartors", that completed first live-fire trials (as a complete system) in the summer of 2005. Current Australian MOD plans state that ADF may start to purchase AICW systems in around 2010-2012.

The Steyr AUG (Armee Universal Gewehr - Universal Army Rifle) had been indevelopment since the late 1960s, as a replacement for venerable but obsolete Stg.58 (FN FAL) battle rifles for Austrian army. It was developed by the Austrian Steyr-Daimler-Puch company (now the Steyr-Mannlicher AG & Co KG) in close conjunction with Austrian Army. The major design is attributed to the three men - Horst Wesp, Karl Wagner and Karl Möser, who developed most of the rifle features. From the Austrian Office of Military Technology the project was supervised by the Colonel Walter Stoll. The new rifle has been adopted by the Austrian Army in 1977, as the Stg.77 (Assault rifle, model of 1977), and production began in 1978. Since then, the AUG gained serious popularity, being adopted by the armed forces of Australia, Austria, New Zealand, Oman, Malaysia, Saudi Arabia, Ireland and some others. It also was widely purchased by various security and law enforcement agencies worldwide, including the US Coastal Guard. The Steyr AUG can be considered as the most commercially successful bullpup assault rifle to date. Since the 1997, the Steyr-Mannlicher produced an updated version of the AUG, the AUG A2.
 In around 2005, Steyr-Mannlicher introduced the most recent version of AUG, the AUG A3. This version is characterized by addition of four Picatinny-type accessory rails - one at the top of the receiver, and three around the barrel, in front of the receiver - at both sides and below it. Therefore there AUG A3 has no standard / integral sighting equipment; instead, any open, telescope or night vision sights can be installed on the upper rail, using appropriate mountings. Lower rail can be used to mount various attachments like tactical front grips, flash-lights, and a specially designed 40mm grenade launcher. Side rails can be used for equipment like laser-aiming devices.

 Some said that the AUG rifle was revolutionary in many respects when it first appeared, but this is not true. In fact, the AUG is a clever combination of the various previously known ideas, assembled into one sound, reliable and aesthetically attractive package. Let's look at this a little closer. Bullpup configuration: The Steyr AUG is not a first military bullpup ever devised. In fact, British Enfield EM-2 and Soviet Korobov TKB-408 bullpup assault rifles precede the AUG by some 25-30 years. The French  FAMAS bullpup also appeared on the scene at the very same time, as the AUG did. Plasticfirearm housing: Another Soviet experimental bullpup design, Korobov TKB-022, had the plastic housing as early as in 1962, and the  FAMAS rifle, again, has this same feature at the same time as AUG did. Telescope sight as a standard: The British  EM-2 bullpup rifle of late 1940s, as well as the experimental Canadian FN FAL prototypes of early 1950s, also featured a low-magnification telescope sights as their prime sighting equipment. A modular design: First systems, consisting of various firearms based on the same receiver and action (automatic rifle, light machine gun, carbine) were originally developed in 1920s in France by Rossignol and in Soviet Russia by Fedorov. Considering all said above, one must agree that the AUG was a logical development of various well known ideas,and a really successful one.
In general, the AUG is known for good ergonomics,decent accuracy and a good reliability.
Technical description.
 The Steyr AUG is a gas operated, magazine fed, selective fire rifle of bullpup layout.

 AUG is built around the aluminium casting receiver, with steel reinforcement inserts. One such insert is used to provide the locking to the removable barrels and the rotating bolt, thus relieving the receiver from most of the firing stress. Other inserts are used as a bearings for the bolt carrier guide rods.

 The AUG uses a short piston stroke, gas operated action, with the gas piston mounted inside the compact gas block, which is fixed to the barrel. The gas cylinder is offset to the right from the barrel. Gas piston has its own return spring, contained inside the gas block. The gas system features a three positions gas regulator, which allows for two open positions (for normal and fouled conditions) and one closed position (for launching the rifle grenades). The gas block also contains a barrel fix / release lock and a front grip hinge. Each barrel has eight lugs, that lock into the steel insert in the receiver, and there's four basic barrel patterns for the AUG: standard rifle barrel is 508 mm (~20 in) long. "Compact" or "Submachine gun" barrel is 350 mm (13.8 in) long, "Carbine" barrel is 407 mm (16 in) long, and the heavy / LMG (light machine gun) barrel is 621 mm (24.4 in) long. On each rifle barrels can be exchanged in the matter of seconds. Each barrel is fitted with the flash hider, and the heavy 621 mm barrel also is fitted with lightweight folding bipods. There's no bayonet lug on Austrian service rifles, but it can be installed if required.

 Barrel replacement procedure, as noted above, takes only few seconds (assuming that the shooter has the spare barrel handy). To remove the barrel, one must take off the magazine, and clear the rifle by operating the cocking handle. Then, grasp the barrel by the front grip, push the barrel retaining button at the gas block, and rotate the barrel and pull it out of the rifle. To install a new barrel, simply push the barrel down into the front of the receiver all the way and then rotate it until it locks. The rifle now is ready to be loaded and fired.

 The bolt system consists of the bolt carrier, which has two large hollow guide rods, attached to its forward part. The left rod also serves as a link to the charging handle, and the right rod serves as the action rod, which transmits the impulse from the gas piston to the bolt carrier. The rotating bolt has 7 locking lugs, claw extractor and a plunger-type spring loaded ejector. Standard bolt has its extractor on the right side, to facilitate right-side ejection, but the left-side bolts (with mirrored positions of extractor and ejector) are available for those who need left-side ejection. The two return springs are located behind the bolt carrier, around the two string guide rods, that are located inside the bolt carrier guide rods. The cocking handle is located at the left side of the gun and normally does not reciprocate when gun is fired, but it can be solidly engaged to the bolt group if required by depressing the small button on the charging handle. On the latest AUG A2 variant, the charging handle was made folding up and of slightly different shape. The AUG action features a bolt stop device, that holds the bolt group open after the last round of ammunition from the magazine is fired. To release the bolt after the magazine replacement, one must pull the charging handle.

 The hammer unit is made as a separate assembly and almost entirely of plastic (including the hammer itself). Only springs and pins are steel. The hammer unit is located in the butt and is linked to the sliding trigger by the dual trigger bars. The safety is of the cross-bolt, push-button type and located above the pistol grip. There's no separate fire mode selector on the AUG rifles. Instead, the trigger itself is used to control the mode of fire. Pulling it half the way back will produce single shots, while the full pull will produce automatic fire. The enlarged triggerguard encloses the whole hand and allows the gun to be fired in winter gloves or mittens.

 The standard sighting equipment of the Steyr AUG rifle is the 1.5X telescope sight, with aiming reticle made as a circle. This circle is so dimensioned so its visible inner diameter is equal to the visible height of the standing man at 300 meters range. The adjustment knobs on the sight are used only for zeroing. The sight housing, which is integral to the receiver on the AUG A1 models, also features an emergency backup iron sights at the top of the telescope sight housing. Some early production AUG rifles of A1 pattern were fitted with receivers that had an integral scope mounts. On the AUG A2 models, the standard scope mount can be quickly removed and replaced by the Picatinny-type mounting rail.

 The housing of the AUG rifles, integral with the pistol handle and triggerguard, is made from the high impact-resistant polymer, and is usually of green (military) or black (police) colour. The housing has two symmetrical ejection ports, one of which is always covered by the plastic cover. The rubber-coated buttplate is detachable and, when removed, opens the access to the rifle internals, including the hammer unit and the bolt group. The buttplate is held in position by the cross-pin, which also serves a s a rear sling swivel attachment point.

 The AUG is fed from the detachable box magazines, that hold 30 (standard rifle) or 42 (light machine gun) rounds. The magazines are made from semi-translucent, strong polymer. The magazine release button is located behind the magazine port and is completely ambidextrous (some said that it is equally NOT comfortable for either hand use).
