6.8 SPC II AR15 Barrel 

The 6.8 SPC (6.8mm Remington Special Purpose Cartridge)was developed in collaboration with the US Army Marksmanship Unit to deliver improved lethality over the 556 NATO cartridge on the M16/AR15 platform.  The 6.8 SPC outperforms 556 NATO, 7.62x39, and 5.45x39 Soviet cartridges in most respects out to 500 yards.  6.8 SPC operates well in short-barrel, close quarters combat configurations in addition to long range situations, making it an extremely versatile round.  Magazines designed specifically for 6.8 SPC are recommended.

AR15Parts.com barrels are sourced from top US manufacturers including Ballistic Advantage, Shaw Barrels, Swan Machine, Wilson Arms, Wilson Combat, ZRO Delta, and others.
