FN SCAR

The FN SCAR (Special Operations Forces Combat Assault Rifle) is a gas-operated (short-stroke gas piston) self-loading assault/battle rifle with a rotating bolt. It is constructed with modularity in mind. The rifle was developed by Belgian manufacturer FN Herstal (FNH) for the United States Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition.[11] This family of rifles consist of two main types. The SCAR-L, for "light", is chambered in 5.56×45mm NATO cartridge and the SCAR-H, for "heavy", is chambered in 7.62×51mm NATO.
