KNIGHTS 31949 SR15 E3 Mod 2 5.56x45mm NATO Black 14.5"

The SR-15 E3 Mod 2 series' 5.56 mm NATO barrel is 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 5.56 mm 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 5.56 mm QDC Signature Reduction Devices.
