History
In the late 1950s,
In the early 1990s, Stoner joined
United States Special Operations Command took interest in the SR-25, particularly its high magazine capacity and faster engagement time compared to bolt-action rifles. After some modifications, SOCOM adopted the SR-25 as the Mk 11 MOD 0 in May 2000. Changes included a shorter 20 in (510 mm) barrel that could fire M118 and M118LR 7.62×51mm NATO rounds and had a quick detachable sound suppressor mount. An 11.35 in (288 mm) free-floating handguard rail system allowed mounting accessories. Flip-up front sights and adjustable back-up iron sights were added, and an M16A2 stock and pistol grip were used.[2]
Beginning in mid-2011, SOCOM began divesting the Mk 11 MOD 0 from their inventory and replacing it with the SSR Mk 20, the sniper variant of the FN SCAR. The Mk 11 was completely replaced by 2017.[3]

The Mk 11 MOD 0 utilizes an Obermeyer 20 in (510 mm) match target barrel, along with a RAS (Rail Accessory System) fore-end made by KAC, consisting of an 11.35 in (288 mm) long match fore-end. The RAS allows for quick attachment/detachment of MIL-STD-1913 components. The aluminum fore-end makes no contact with the barrel forward of the receiver, allowing for improved accuracy. The Mk 11 MOD 0 has an empty weight of 15.3 lb (6.9 kg), and an overall length of 45.4 in (115 cm). The civilian version, using the longer 24 in (610 mm) match barrel, is guaranteed to produce groupings of less than 1 in (25 mm) at 100 yd (91 m), or 0.3
During the Iraq War, the United States Marine Corps ordered 180 Mk 11 MOD 1 rifles which were Mk 11s equipped with the upper receiver of the M110 Semi-Automatic Sniper System. The M110 upper gave the Mk 11 MOD 1 a URX modular rail system and a flash suppressor on the barrel. These saw limited use before they were phased out when the Marines chose to purchase the Mk 11 MOD 2, which was simply the USSOCOM and U.S. Navy designation for the complete M110 rifle.[5]
The SR-25 Enhanced Match (E.M.) Carbine is very similar to the KAC M110 Semi-Automatic Sniper System,[4] though the M110 utilizes the newer URX Rail system, a length-adjustable fixed buttstock, and an integrated flash suppressor. Starting in late 2011, USMC snipers began to replace Mk 11 MOD 0 rifles with the M110 on a one-for-one basis.
