For sale are several AR15 16" barrels in 5.56 NATO caliber. Made from CrMoV, 1:7 twist, mid-length gas system with .750" gas hole, medium profile, and most are finished in a nitride black coating. I have a couple available cerakoted in FDE, Burnt Bronze, and OD Green. Black nitride are $150 each, and cerakoting barrels are $220. Very high quality barrels that are hard to find! Won't last long!
