It is perfectly suited for use at the range, in a 3-Gun match, or in the field pursuing game.
What is Melonite barrel treatment?
Melonite® is a thermochemical treatment for improving the surface properties of steel parts. It exhibits predictable and repeatable results in the treating of low and medium carbon steels, alloy steels, stainless and austenitic steels, tool and die steels, cast and sintered iron.
What are CHF barrels?
The CHF method provides exceptional control of the bore and groove dimensions, resulting in excellent dimensional accuracy and tolerance. A cold hammer forged barrel has smoother barrel surfaces compared to other barrel manufacturing methods such as button rifling and cut rifling.
Why is a chrome lined barrel better?
While chrome lining offers superior corrosion resistance to various external weather conditions, it also serves to significantly reduce throat erosion, allowing shooters to enjoy sub-MOA accuracy potential for as much as 20,000 rounds of normal use with factory match ammunition.
