FN SCAR


     On October 15, 2003, the United States Special Operations Command (US SOCOM) issued an application for an assault rifle for special operations groups (SCAR). This request required a new combat rifle, adjusted to the future needs of the United States Special Forces, which differed from the generic needs of the American army covered by the new HK XM8. The key difference is that while the XM8 has a unique caliber, 5.56x45 mm NAT, the SCAR had to have variable caliber to cover different tactical needs. The initial requirements included two basic versions of the SCAR system, the SCAR Light (SCAR-L) with the 5.56x45 mm caliber and the SCAR Heavy (SCAR-H) with the most powerful 7.62x51 mm and should be easily to other calibers such as 7.62x39 mm of Soviet origin and probably to other calibers like the 6.8x43 mm Remington SPC, developed especially for the American special forces. The main idea is that special operations teams have a variety of tactical options, from SCAR-L CQC with 5.56mm caliber and short gun for urban combat to SCAR-H variant with long barrel for precision rifle use, others options are the use of enemy ammunition on missions behind the front line

     Both SCAR-L and SCAR-H have three versions, standard (S), close combat (CQC) and sniper (SV). All these variants, regardless of caliber and exact configuration have the same control system, handling and maintenance process and the same optional equipment, such as sights, laser pointers, etc. At the end of 2004 the US SOCOM announced that the winner of the contract was FN USA, a subsidiary company of the Belgian company Fabrique Nationale Herstal. By mid-2005 the first SCAR rifles were in the hands of US special forces. Since the US SOCOM uses "mark" designations such as the United States Navy the SCARs were officially designated as Rifle Mark 16 5.56 mm (SCAR-L) and Rifle Mark 17 7.62 mm (SCAR-H), it is expected that the Mk . 16 and the Mk. 17 will gradually replace the remaining US SOCOM rifles, such as the M4 carbine, the M16, the M14 and the Mk precision rifles. 25.

     In the end it turned out that the FN SCAR rifles were not based on previous weapons, but designed from scratch. In all variants of FN SCAR rifles operate by gas, with short stroke piston action with bolt locking rotation. The bolt of seven radial locking teeth that lock directly into the extension of the barrel. The receiver is made of two parts, upper and lower, connected with two crossed pins. The top is extruded aluminum, the bottom is made of polymer. SCAR-L and SCAR-H use similar top receivers that differ only in the size of the ejection window. Other different parts include specific caliber bolt, barrel, and lower receiver with integral compartment cover. The common parts between SCAR-L and SCAR-H are astonishingly 90%. The guns are quickly dismantled, and are held in the upper receiver with two cross screws. The barrel change procedure requires a minimum amount of tools, it only takes several minutes and there is no need to adjust the head space after the change.

     The trip unit with ambidextrous modes of safety and trip selectors allow isolated firing and fully automatic fire, with no provisions for bursts of limited length. The loading lever can be easily installed on either side of the gun, so the upper receiver has respective cuts on both sides. The top of the upper receiver is covered by a full-length Picatinny rail (MIL-STD 1913); Additional Picatinny rails are mounted on both sides and in the frame of the floating free handrail. The laterally folded polymer stock is adjustable for the length of the traction, and is shaped to provide rest to the cheek with the positive adjustable cheek support. The SCAR rifles feature removable, adjustable iron sights, with folding diopter-type folding on the rail receiver, and folding front sight gas block. Any additional type of observation equipment, required for current tasks, including telescope and night vision, can be installed with MIL-STD 1913 compatible media. The Mk.16 SCAR-L rifle will use improved M16 steel type loaders; the Mk.17 SCAR-H will use 20 patented cartridges with 7.62x51 NATO chamber or standard AK type M43 chargers proposed for the 7.62x39 chamber. Current prototype SCAR rifles do not have bayonet mounts, and probably never have one.
