The SR-25 (Stoner Rifle-25) is a semi-automatic sniper rifle designed by Eugene Stoner and made by Knight's Armament Company. The SR-25 uses a rotating bolt and a direct impingement gas system. It is loosely based on Stoner's AR-10 (and therefore on the AR-15/M16), rebuilt in its original 7.62x51mm NATO caliber. Up to 60% of parts of the SR-25 are interchangeable with the AR15/M16 - everything but the receiver, the hammer, the barrel assembly and the carrier/bolt. SR-25 barrels were originally manufactured by Remington Arms with its famous 5R (5 grooves, rounded) rifling, with twist 1:11.25 (1 turn in 11.25" (286 mm)). The heavy 24" (609 mm) barrel is free-floating, so handguards are attached to the front of the receiver and do not touch the barrel. The SR-25 match rifle has no iron sights, and all models have a Picatinny-Weaver rail system on the top of the receiver to accept different scope mounts or M16A4 carrying handle with iron sights (front sight mounted on the rail located on the forward end of the non-modular handguard). It is designed to shoot at a precision of 1 Minute of angle, which corresponds to 1-inch groups at 100 yards, or 6-inch groups at 600 yards, etc.
