A gas-operated, magazine fed, semi-automatic rifle with a collapsible synthetic buttstock. The receiver is two-piece, with an upper and a lower, a right hand ejection port with hinged cover, a plastic pistol grip, a charging handle at top rear and a MIL-STD-1913 rail on the top. The barrel is a free-floating design with a perforated tubular handguard with rail mounts, and a short muzzlebreak at the end. The receiver, pistol grip and buttstock have been spray-painted in a tan/brown camouflage pattern.
The Mk 11 Mod 0 was adopted by US Special Operations Command in May 2000. The rifle is based on the SR-25 designed by Eugene Stoner and manufactured by Knights Armament Company (KAC). The design of the rifle combines aspects of both the AR-10 and AR-15 designs with more modern technology. The weapon is a semi-automatic, gas operated, 7.62mm NATO caliber precision rifle with a free-floating 20” match grade barrel, MIL-STD-1913 rail mount equipped handguard and upper receiver, and a Crane designed adjustable buttstock. The rifle originally came with a Leupold Mk 4 telescope, a Harris bipod and KAC quick-detach sound suppressor. The rifle was painted in a camouflage pattern by Naval Special Warfare personnel during its use by operational units.
This rifle was carried by then-Senior Chief Britt “Slab” Slabinski while serving as Team Leader of MAKO 30 during the Battle of Takur Ghar in support of Operation Anaconda. Op Anaconda was the first major ground combat operation in Afghanistan during Operation Enduring Freedom. Master Chief Petty Officer Slabinski was awarded the Medal of Honor on May 24, 2018 for his actions in Afghanistan during Operation Anaconda in 2002.
