Knights Armament Company, SR-15, 14.5″ Carbine Mod2, Complete Upper Receiver

The SR-15 E3 MOD 2 series’ 5.56mm NATO barrel is manufactured for military grade durability, and is free-floated inside a URX4 M-LOK handguard. Included in this upper receiver group is Knight’s new E3.2 bolt. Dual ejectors ensure clean and consistent ejection even when a traditional high-backpressure suppressor is used. Refined Lug geometry and optimized material selection ensures lug durability in excess of even the industry-leading KAC E3 bolt. A viton o-ring prevents extractor vibration and lift, and a hard chrome exterior simplifies cleaning and maintenance. The 5.56mm 3-Prong Flash Eliminator interferes with propellant gas combustion forward of the muzzle to significantly reduce flash signature, will not ring upon firing or when struck, and is compatible with the Knight’s line of 5.56mm QDC Signature Reduction Devices.
