FN SCAR

The Special Operations Forces Combat Assault Rifle (SCAR) is a gas-operated (short-stroke gas piston) self-loading rifle with a rotating bolt and a firing rate of 625 rounds/min. It is constructed to be extremely modular, including barrel change to switch between calibres. The rifle was developed by FN Herstal (FNH) for the United States 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 5.56×45mm NATO cartridge and the SCAR-H, for "heavy", fires 7.62×51mm NATO. Both are available in Long Barrel and Close Quarters Combat variants.
