Melonite/Nitride/QPQ Treated: Read about this process being better than Chrome lined bores

These barrels have been treated with a Black Nitride treatment. The result of this process is markedly improved surface properties on ferrous metal parts while maintaining dimensional and shape stability. Metal components treated with Black Nitride have increased wear-resistance, fatigue strength, corrosion resistance, lubricity and cosmetic appeal. Often replacing the more Finicky  processes of hard chrome or nickel plating, Black Nitride gives better corrosion protection. Additionally, Black Nitride is commonly used as an alternative to high temperature conventional heat treatments such as Parkerizing or carbonizing.

Accuracy:

Our H-Bar Barrels are capable of 1/2" MOA 5 shot group at 100 Yards. This means all 5 shots will be touching.
