Infantry rifle : FN SCAR. (M.LA)

The SOF Combat Assault Rifle,[3] or SCAR, is a modular rifle made by Fabrique Nationale de Herstal (FNH) for the U.S. Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition. This family of rifles consist of two main types. The SCAR-L, for light, is chambered in the 5.56x45mm NATO cartridge and the SCAR-H, for heavy, fires 7.62x51mm NATO ammunition. Both are available in further variants such as Long Barrel or CQC (Close Quarters Combat). The FN SCAR system completed low rate initial production testing in June 2007 and was scheduled for limited fielding in the fall of 2007.[4]

Overview
The SCAR is available in two calibers, and in versions for short and long range combat. It emerged as the winner of a US SOCOM competition to find a new rifle for special forces begun in 2003. Other competitors included entries by Colt and the Robinson Arms XCR. Heckler & Koch had submitted the XM8 as a general issue replacement for the M4 and M16 for the US Army, but the program was canceled.
The SCAR is manufactured in two main versions; Light (SCAR-L, Mk 16 Mod 0) and Heavy (SCAR-H, Mk 17 Mod 0). The L version fires 5.56x45mm NATO using improved M16 rifle magazines. The H fires the more powerful 7.62x51mm NATO from a newly designed 20-round magazine (this full-sized cartridge makes the SCAR-H a battle rifle). Different length barrels will be available for close quarters battle and for longer-range engagements. The initial solicitation indicated that the SCAR-H would also be chambered for the 7.62x39mm M43 cartridge. However, FN is not currently offering other calibers
