A compact, light 300 BLK upper, with better cooling.
Davidson Defense took the best aspects of the 300 Blackout cartridge even further with this 8.5" upper. It sports a uniquely skeletonized, free-float M-LOK and Picatinny handguard with a stubby compensator for improved accuracy and recoil control. Its short barrel and fast twist rate provide stability and reliable cycling for both supers and subs.
