16" 300 blackout Melonited - Pistol Length Gas System with a 15" SDX Rail, BCG & CH! This setup makes the ultimate 30cal AR15 for hunting or just
punching really large holes in things. The extended rail allows for a
longer sight radius, bipod attachment near the muzzle for added
stability and extra rail attachments space. These uppers feature a
pistol gas system for added reliability and flexibility in ammo
selection as the shorter system runs at higher pressures for the some
times finicky 300 blackout round. We have a very limited supply of these barrels and they won't last long at these sale prices, get yours while supplies last!Specifications:
