The FN SCAR-L, Special Operations Forces Combat Assault Rifle Light, was adopted by US SOCOM in 2009 to replace the M4 Carbine in special operations service. The short-stroke gas piston system avoids the direct-impingement heat and gas fouling of the M4, and the adjustable stock and reciprocating charging handle provide ambidextrous operation.
