Our 5.56 chambered 7.5 inch USGI Profile Carbine Barrel is machined from 4150 Chrome Moly Vanadium steel with a Black Nitride Corrosion Resistant Finish and Black Nitride Corrosion Resistant coated M4 feed ramp extension.

4150 has a 0.50% carbon content and is used for barrels that need to be tougher, have more strength, and higher hardness than 4140 or 4130 can provide. It's a little less common and takes a little extra effort to machine but produces the right results.
