Knights Armament (KAC)
Knight's Armament FF RAS (SR-25 MK11 MOD 0). Rail is approximately 12 1/4" long including the barrel nut. Free floats the barrel. Picatinny rails on all four sides allow endless possible mounting solutions for accessories such as sling mounts, vertical forearm grips, flashlights and more.
The Mk11 sniper rifle saw duty in Afghanistan, Iraq and other theaters during the War on Terror. The Mk11 Mod0 was first introduced as a variant of the SR25 rifle by Knights Armament to the US Navy and SOCOM in 2000. The rifle was designed to use the 7.62mm NATO Mk118 match grade ammo with a 20" Obermeyer 5R barrel.
The RAS comes with three 11 rib panels to help protect the rails from damage. Will not fit the Armalite AR-10. Installation available, special tools required.
