A gas-operated, magazine fed, semi-automatic rifle with a collapsible synthetic buttstock. The receiver is two-piece, with an upper and a lower half, 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 a Rail Interface System and a short muzzle break at the end that allows the quick attachment of a sound suppressor. The receiver, pistol grip and buttstock have been spray-painted in a tan/brown camouflage pattern. The barrel assembly is a replacement installed by Naval Special Warfare personnel and is not camouflaged.
The SR-25 was designed by Eugene Stoner and manufactured by Knights Armament Company (KAC) in the early 1990’s. 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 Naval Surface Weapons Center, Crane-designed adjustable buttstock. The rifle would have been equipped with a Leupold Mk 4 telescope, a Harris bipod, an AN/PEQ-2 infrared illuminator and a KAC quick-detach sound suppressor. The SR-25 was adopted as the Mk 11 Mod 0 by US Special Operations Command in May 2000.
This example was carried by then-Senior Chief Britt “Slab” Slabinski in Afghanistan during 2002.
