Knight’s Armament SR-25 E2 16″ APC M-LOK Rifle KM 31955

The Knight's Armament Company SR-25 E2 APC (Advanced Precision Carbine) in 16-inch M-LOK configuration is the commercial evolution of the rifle that gave birth to the U.S. Army's M110 Semi-Automatic Sniper System. This is not a clone or inspired-by build: it is produced directly by KAC to the same exacting standards as their military contracts. The E2 designation reflects the second-generation enhanced bolt system with a high-pressure dual ejector that dramatically improves reliability in both suppressed and unsuppressed configurations across adverse conditions.

The 16-inch medium-contour barrel wears KAC's proprietary 5R rifling with a 1:10 twist optimized for 7.62 NATO, and ships with a KAC QDC Dual-Port Brake that is directly compatible with KAC's full line of 7.62mm Signature Reduction Devices for suppressed shooting. The URX6 free-float handguard features seven sides of M-LOK attachment points and a continuous top MIL-STD-1913 rail for optics and accessories. The E2 APC represents the definitive 16-inch 7.62 NATO semi-automatic precision carbine, built to the standard that all others are measured against.
