Knight's Armament produces the SR-25, 7.62 caliber precision rifles from the solid foundation of the original 7.62 AR-10 rifle the Mr. Eugene Stoner developed in the 1950's. In 1989, Mr. Stoner joined with Knight's Armament and developed the SR-25 by combining his classic AR-10 and AR-15 platforms. KAC's current SR-25 features a free-floating barrel rifle system that, from the very beginning, was conceptualized as a precision target rifle. This platform is currently the primary firearm of thousands of military sniper units. KAC's Stoner rifles, such as the MK 11 and M110SASS series, has long been considered to be some of the most accurate and reliable semi-automatic 7.62mm rifles ever produced.
Knight's Armament has 21 years of experience in 7.62mm development, refinement, and service. The SR-25 was first conceptualized with its primary function being a sniper rifle. It delivers remarkable shooting accuracy with .5 MOA being attainable in a multiple target environment. The MK11 MOD0 and the M110 have embodied this experience and helped drive our company's renowned pursuit of perfection ultimately leading to the Enhanced Match Series of SR-25's.
The new Enhanced Match (E.M.) Rifle combines some of the best characteristics from the combat proven MK11 MOD0 and the M110 military rifles. The E.M. Rifle's Free-Floating barrel is a clone of the legendary MK11 MOD0's, but its Upper Receiver Extending (URX) forend with integral folding front sight was developed for the Army's XM-110 Rifle. The E.M. Rifle's ambidextrous magazine release was also a noteworthy XM-110 feature and the lightweight butt-stock is the same as the MK11 MOD0's. The SR-25 is widely used among the most elite special forces units around the world being first deployed and used by the US Navy Seals.
