sr-25

The SR-25 (Stoner Rifle-25) is a designated marksman rifle and semi automatic sniper rifle designed by Eugene Stoner and manufactured 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, rebuilt in its original 7.62×51mm NATO caliber. Up to 60% of parts of the SR-25 are interchangeable with the AR-15 and M16—everything but the upper and lower receivers, the hammer, the barrel assembly and the bolt carrier group. SR-25 barrels were originally manufactured by Remington Arms with its 5R (5 grooves, right twist) rifling, with twist 1:11.25. The heavy 24-inch (610 mm) barrel is free-floating, so handguards are attached to the front of the receiver and do not touch the barrel.
