Ares Armor Barrel

---

Barrel: The featured barrel which is 16 inches in length is made from 4142 Steel, has a 1:10 twist, is Black Nitride coated and has a Carbine length gas system.

Black Nitride Process: This finishing process is a surface conversion process in place of industrial hard chrome and is therefore inherently free from nodules, flaking, pits, stripping, or anode burrs. The process results in chemical and structural composition changes that can be described as a case hardening to a depth of 0.005� of the alloy leading to increased surface hardness, lower coefficient of friction, enhanced surface lubricity, improved running wear performance, increased sliding wear resistance, enhanced corrosion resistance and heat resistance over industrial hard chrome. The process is a surface conversion and does not add material to the internal dimension of the bore. With hard chrome, the bore must be manufactured oversized or honed and electro-polished to make the interior dimension oversized making room for the chrome plating. This plating is inconsistent which is the reason sniper or target barrels are typically not chromed. It has proven superior as a surface finish to phosphate with oxidization when subjected to MIL-STD-810f salt fog/spray testing and is a scratch resistant flat black finish.
