Snipes Armory's first bullpup rifle, the BBR is a 7.62mm beast despite being shorter than a M4 CQBR (with stock fully extended). The bolt mechanism is unique in that in addition to moving backwards, it moves up ever so slightly to counter muzzle rise. The magazine release is located on the forward grip/enlarged trigger guard to allow for easier magazine changes, and the charging handle, pistol grip, rear sight and magazines are compatible with most AR-10 parts. This allows easier customization of the rifle.
