The U.S. Special Operations Command SOCOM (Special Operations Command) for its next-generation assault rifle selected new modular and adaptive arms, under the program SCAR (SOF Combat Assault Rifle). SCAR is modified version of the famous assault rifle FNC. SOCOM wanted the possibility of using two different caliber so SCAR is planned in two versions, the SCAR-L (SCAR Mark 16 – Light) uses ammunition 5.56 × 45 mm NATO placed in an improved framework rifles M16 magazines and SCAR-H (Mk 17 SCAR – Heavy, heavy) with caliber 7.62 x 51 mm NATO within the framework of the new design capacity of 20 rounds. The aim is that these two versions of rifles replace the current five varieties of guns that are used in the operations of the U.S. Army Special Forces.

 

SCAR rifle uses a conventional concept and a system of loans with short gas piston and rotary hammer stopper. The system is similar to a machine gun FN Minimi / M249 SAW, and is less sensitive to fine sand, dust or other debris. It has the ability to easily set up a variety of accessories, such as various riflescopes, grenade launchers, flashlights and so on picatiny rails.

New weapon produces a renowned Belgian company FN (Fabrique Nationale) through its Herstal FNH USA company in the U.S. in two versions under the name SCAR, but there is also others that will be used by munitions 6.8 × 43 mm Remington SPC (especially developed for U.S. Special Forces ) and 7.62 × 39 mm M43. The possibility that the gun used by special forces shot SCAR 7.62 × 39 mm (bullet for AK-47 Kalashnikov) is associated only with the spread of the bullet and its availability in the areas of special operations forces. Rifle SCAR which will be adapted for the Russian ammunition 7.62 mm × 39 will receive an additional tube easier.

SOCOM operatives were looking for a higher caliber, and 7.62 × 51 mm, because it allows more murderous power at a greater distance. In the case of action in an urban environment stronger caliber also has certain advantages. Stronger the bullet easily penetrate obstacles such as walls and doors, and is more effective when shooting at vehicles.

SCAR assault rifle is constructed as a modular weapon that can easily and quickly be adapted for a variety of uses. Both SCAR-L and SCAR-H are initially available in three versions, Standard (Standard – S), melee (Close Quarters Combat – CQC) and sniper version (Sniper Variant – SV). At the same gun may be used different tubes and modify them, if necessary, with a determining factor for the replacement of the requisite specificity. Standard length of pipe for version SCAR-L will be 351 mm (13.82 inches) for close combat length 253 mm (9.96 “) and the sniper version, with a length of 457 mm (18″). Length of complete rifles in this release will move from a low of 612 mm (31.02 “) to a maximum length of 850 mm (34″). For a version of the SCAR-H will be available tube length 330 mm (13 “), 400 mm (15.75″) and 500 mm (19.68 “) when looking for maximum accuracy. The minimum length of this version is 798 mm (38.7 “), while the maximum is 1.021 mm (40.2″). Special operations forces will be able to change the tube if necessary to the task, although the decision on the type of pipe remains the responsibility of officers. The hose takes less than 5 minutes, with certain possible adjustments and changes in caliber. Variant of the SCAR-L will replace the gun for close combat M4A1, Mk 18 (Close Quarters Battle Rifle – CQBR) and the Mk 12 SPR, and SCAR-H M14 changes and sniper Mark 11th

Crate rifle is constructed of two parts, upper and lower, connected with two cross-pins. The upper part is made of aluminum, while the lower of the polymer. SCAR-L and SCAR-H use similar upper part of the case that differs only in the size of the hole to eject the shell.

In each version of SCAR rifles being integrated multipurpose MIL-STD 1913 rail (Picatiny) for flexible configuration of weapons for different missions. On the upper side of the front to the rear sight is set Picatinny Rails provides for setting optical sights, night-vision devices and surveillance cameras. Additional rails are placed on the sides and underneath the front of the rifle. All these tracks are designed as an integral part of improving the stability of the structure of the rifle before firing, holding insulation harmonic vibrations caused by automatic fire.

In SCAR rifle butt and telescopic and folding. A telescoping feature for adjusting various configurations personal equipment of soldiers, armor or clothing, which may require a change in the position of a rifle given to the distance between the user’s shoulders and triggers. Folding stock is more convenient, because it allows special forces to open fire and under civilian clothes when he made the butt, as well as fighting from vehicles, helicopters, parachute in similar situations. The user has the option to adjust the butt of his body, and achieve the best visibility, regardless of whether the optical sight installed or not.

Handrail rifle was developed using extensive anthropometric measures for determining the shape and size best suited for the soldiers. Available adapters allow a soldier to adjust the grip to your hand. Redesigned grip provides better handling and control. Fire selector moves from position to stall or semi-automatic and back in only 90 ° and is set for both right and left hand (the M4A1 regulator is necessary to rotate 180 ° and is not set for both hands). With ammunition box is configured for use with both hands and is protected from accidental removal. Also, the filling lever can be easily installed on one side or the other because it has the openings provided on both sides.

Rate of fire of only 600-650 grains per minute (900 grains of M4A1) facilitates management of arms and creates a shorter flash before firing. Enhancements to provide mechanisms that can solve many of the problems encountered in previous automatic rifles, including heating and exhaust gases. This rifle is much easier to clean and maintain than the M4A1.

Both variants of the SCAR L and H are 90% identical common components, which has never before achieved with such different calibers 5.56 × 45 × 7.62 mm and 51 mm. The only parts that are different for both variants are those that relate specifically to the caliber, or stuck pipe 5.56 mm or 7.62 mm, frame, shutter and aperture head bouncer. Common components for all models of guns are very important because they reduce the time required for training and adapting different versions required users for a variety of missions. At SCAR rifles are mounted variable, adjustable steel tombstones. Rear sight is mounted on the top rail of the front sight on the gas regulator.

Frames for bullets are different, but they are much improved compared to the previous. SCAR-L to use enhanced steel frame with a M16 rifle, while the SCAR-H use a new box with 20 bullets in the caliber 7.62 × 51 NATO framework or standard 7.62 × 39 M43 with AK (Kalashnikov). Each version of the SCAR rifle will be equipped with 10 frames.
Pipes are designed for a life cycle of 35,000 grains, and lives for the entire system to 90,000 grains. At the end of the cycle, or in the event of failure, the pipes can be replaced in a few minutes by unscrewing two bolts. Average number of grains between the two delays of 2,000 grains.

The empty weight of the SCAR-L is 3.08 kg, while the weight versions of the SCAR-H amount to 3.26 kg.

FN Herstal company developed a grenade launcher for the SCAR program. It is enhanced modular grenade launcher EGLM (Enhanced Grenade Launcher), which is mounted under the barrel, it opens on the side allows charging long 40 mm grenade, can be handled, and the right and left hand. Available butt of a Private EGLM. Fire Management is excellent and has a built-in laser rangefinder with automatic elevation.

When it is pointed EGLM low or high on the reticle glows red signal, and if it is centered on the target reticule glows green. For hidden targets, or those behind natural cover, hindsight gives the distance to the target. EGLM is compatible with the latest programmed 40 mm ammunition exploding in the air above the target.

Production of the different versions of SCAR rifles began in late 2005. , and the final distribution should be finished by 2011. year, or earlier. SOCOM is expected to deliver up to a total of 85,000 copies variants SCAR-L and 15,000 copies SCAR-H variants. SCAR rifle company will produce FN Manufacturing LLC.
