Pro2a Tactical is the one of the only few to offer 7.62x39 AR-15 NR Side Charging Upper Assemblies. The 7.62x39 round is cheap to shoot, yet ballistically perfect for short/medium range hunting and self defence. It has slightly more energy than a 30-30 and a supersonic 300 Blackout and is a devastating round. Our BCGs come with the extended firing pin to ignite the hard Russian primers found on Russian ammo. Our 7.62x39 AR-15 NR Side Charging Complete Uppers with BCG pins right on to your standard AR-15 lower and together with 7.62x39 AR magazine, you are ready for the range or those pesky little wild boars. Pro2a Tactical's AR-15 NR Side Charging Uppers are made right here in the USA with the highest quality components and covered by our limited lifetime warranty.
