6.8 SPC AR15 Upper Assembly / 6.8 SPC Complete Upper Receiver for AR15

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.  The 6.8 SPC bolt carrier group is compatible with 224 Valkyrie, however magazines designed specifically for 6.8 SPC are recommended.
