KNIGHTS ARMAMENT UPPER RECEIVER KIT 5.56 NATO 11.5″ BARREL M-LOK

Knights Armament Upper Receiver Kit Features

The Knights Armament Upper Receiver Kit, SR-15 CQB MOD 2, features a 5.56mm NATO 11.5″ chrome lined barrel manufactured for military grade durability and is free-floated inside a URX4 M-LOK handguard. An improved E3 round-lug bolt design both enhances function and increases bolt life far beyond the industry standard. 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 Knights line of 5.56mm QDC Signature Reduction Devices.
