AR-15 6.8 SPCII 12.5" Pistol Upper Assembly / Mlok /Triport

AR-15 6.8 SPCII 12.5" Pistol Upper Assembly / Mlok /Triport is the most economical way to upgrade your standard AR-15 rifle with the 6.8 SPC II modified caliber. The 6.8 SPC (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. The 6.8 SPC is extraordinarily accurate and reliable, and used by many special operations units. This barrel conforms to SAAMI specs for 6.8 SPC, Type 2. (6.8 SPC II has a 0.136" bolt face depth.) This is a highly accurate, precision machined, match grade barrel.
