Knights Armament AR-15 SR-15 Carbine Mod 2 Upper Receiver Assembly 5.56x45mm 14.5″ Barrel URX 4 M-LOK Handguard

The Knights Armament 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. 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. This upper features the Knights Armament E3.2 Dual Ejector 5.56 Bolt for reliability.
