Our 5.56 chambered 16 inch Primus(tm) Profile Mid-length 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.

The Primus(tm) profile is Hughes Ballistics patent pending innovation that improves cooling, reduces overall weight and moves the center of gravity back towards to shooter to increase control.

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.
