20" 6.8 SPC Stainless Heavy Contour Barrel AR15 Rifle Upper Assembly with 15" Rail and A2 Flash Hider
The 6.8mm SPC was designed to address the deficiencies of the ballistics of the 556 NATO cartridge currently in service with the armed forces of all NATO-aligned countries. The cartridge was the result of the Enhanced Rifle Cartridge Program. The 6.8 SPC was initially developed by Master Sergeant Steve Holland and Chris Murray, a United States Army Marksmanship Unit gunsmith, 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 goal was to create a cartridge that would bridge the gap between 5.56 mm and 7.62mm.
