Product Information

The 6.8 SPC is a very unique cartridge. With nearly 40% more muzzle velocity than the standard 5.56, the 6.8 is offers a considerable improvement in power and range but still allows the shooter to maintain control during rapid fire. Changing your AR-15 over to the 6.8 SPC will yield superior long range capabilities, more energy and more knock down power. This barrel is pre-drilled for a 0.750" gas block and includes a complete bolt assembly.
