The SR-25 (Stoner Rifle-25)^[1] is a designated marksman rifle and semi automatic sniper rifle designed past Eugene Stoner and manufactured by Knight's Armament Visitor.^[1]

The SR-25 uses a rotating bolt and a direct impingement gas system. Information technology is loosely based on Stoner'due south AR-10, rebuilt in its original vii.62×51mm NATO caliber. Upwardly to sixty% of parts of the SR-25 are interchangeable with the AR-15 and M16—everything but the upper and lower receivers, the hammer, the butt assembly and the bolt carrier grouping.^[ane] SR-25 barrels were originally manufactured by Remington Arms with its 5R (5 grooves, correct twist) rifling, with twist 1:11.25. The heavy 24-inch (610 mm) butt is free-floating, then handguards are attached to the front of the receiver and do non touch the barrel.

History [edit]

In the late 1950s, Eugene Stoner designed the AR-10 boxing burglarize to equip U.South. troops. Information technology was accurate for an motorcar-loading rifle, only it lost the competition to the M14 burglarize. The patent rights for the AR-10 and the AR-xv were sold to Filly's Manufacturing Company. Colt focused on the AR-fifteen, giving others the power to capitalize on the AR-10 organisation.^[2]

In the early 1990s, Stoner joined Knight's Armament Company. He connected his AR-10 blueprint work and joined it with the direct gas system of the AR-fifteen. The terminate result was the SR-25 (calculation together the numbers of the AR-x and AR-15) which improved the AR-10 design with M16A2 advancements and parts commonality. The original SR-25 was released in the early on 1990s and had a heavy gratuitous-floating 24 in (610 mm) lucifer grade barrel with a fiberglass handguard. It had a apartment pinnacle upper receiver with a Mil-Std 1913 rails for mounting optics and a 2-stage match grade trigger. The commodities carrier was similar to the AR-ten's, beingness chrome plated and having a captive firing pin retainer pin. The SR-25 was designed specifically to fire 168 gr (10.9 g) open up-tip match cartridges. Accuracy was guaranteed at or under i minute of bending. At starting time, AR-x type 20-round magazines were used, but they were after replaced by steel 20-round magazines resembling those used by the M16.^[2]

The U.s.a. Special Operations Command took interest in the SR-25, peculiarly its high magazine capacity and faster engagement time compared to bolt-action rifles. Afterwards some modifications, SOCOM adopted the SR-25 every bit the Mk 11 Modern 0 in May 2000. Changes included a shorter xx in (510 mm) barrel that could fire M118 and M118LR 7.62×51mm NATO rounds and had a quick detachable sound suppressor mount. An eleven.35 in (288 mm) free-floating handguard track system allowed mounting accessories. Flip-up front sights and adaptable redundancy iron sights were added, and an M16A2 stock and pistol grip were used.^[2]

Kickoff in mid-2011, SOCOM began divesting the Mk 11 Modernistic 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]

Design [edit]

The SR-25 enhanced friction match burglarize utilizes the newer URX II Picatinny-Weaver runway system, rather than the older Mk eleven gratis-floating RAS, on the top of the receiver to accept different telescopic mounts or a conveying handle with iron sights (front sight mounted on the rail located on the forward end of the non-modular handguard).^[four] The lucifer version is designed to shoot at a precision of 0.5 minutes of bending, which corresponds to 0.5-inch (13 mm) groups at 100 yards (91 yard).

The Mk eleven Mod 0 arrangement is chambered for 7.62×51mm NATO, and is designed for friction match-grade ammunition. The Mk xi organization includes the rifle, twenty round box magazines, QD (Quick Detachable) telescopic rings, Leupold Marking 4 Mil-dot riflescope, Harris swivel-base bipod on a Knight's mount, and QD sound suppressor, which is as well manufactured by Knight's Ammunition Co.^[1] Flip-up BUIS (Support iron sights) are attached to the modified gas block and upper receiver.

The Mk xi Mod 0 utilizes an Obermeyer 20 in (510 mm) friction match target butt, forth with a RAS (Rails Accessory System) fore-end made by KAC, consisting of an 11.35 in (288 mm) long match fore-wnd. The RAS allows for quick attachment/detachment of MIL-STD-1913 components. The aluminum fore-terminate makes no contact with the barrel forward of the receiver, allowing for improved accuracy. The Mk 11 Mod 0 has an empty weight of fifteen.3 lb (6.9 kg), and an overall length of 45.four in (115 cm). The civilian version, using the longer 24 in (610 mm) match barrel, is guaranteed to produce groupings of less than one in (25 mm) at 100 yd (91 grand), or 0.3 angular mil, using factory lucifer loads.

During the Republic of iraq State of war, the Us Marine Corps ordered 180 Mk 11 Modernistic 1 rifles. These were Mk 11s equipped with the upper receiver of the M110 Semi-Automatic Sniper Organisation. The M110 upper gave the Mk eleven Modern 1 a URX modular track system and a flash suppressor on the butt. These saw express use before they were phased out when the Marines chose to buy the Mk 11 Mod 2, which was simply the USSOCOM and U.S. Navy designation for the complete M110 burglarize.^[five]

The SR-25 Enhanced Friction match (E.M.) Carbine is very similar to the KAC M110 Semi-Automatic Sniper Organization,^[iv] though the M110 utilizes the newer URX Rail arrangement, a length-adjustable fixed buttstock, and an integrated flash suppressor. Starting in tardily 2011, USMC snipers began to supercede Mk 11 Mod 0 rifles with the M110 on a ane-for-one basis.
