The accuracy and precision of Satern barrels is surpassed by no one in the firearms industry. The 6.8 SPC II (6.8x43mm) was developed by the United States Army Marksmanship Unit to offer superior downrange lethality over the 5.56 NATO/.223 Remington in an AR pattern service rifle with minimal loss of magazine capacity and a negligible increase in recoil. 6.8 SPC BCG and magazines are required. This barrel conforms to SAAMI specs for 6.8 SPC, Type 2. (6.8 SPC II has a 0.136" bolt face depth.)
