18" 6.8 SPC II Shaw Stainless Medium Barrel - 15" Rail - A2 Flash Hider - AR 15 Upper

18" 6.8 SPC II Shaw Stainless Medium Barrel AR15 Upper Receiver with 15" Rail and A2 Flash Hider

The 6.8mm SPC was designed to offer superior downrange lethality over the 5.56 NATO/.223 Remington in an M16-pattern service rifle with minimal loss of magazine capacity and a negligible increase in recoil. The 6.8 SPC round effectively bridges the gap between 5.56x45 and 7.62x51.
