What a deal.......
All parkerized barrels start with 4140 Gun Barrel quality steel. Heat Treated and Stress Relieved to a hardness of Rockwell C 28-32. Or they use the 416 Gun Quality Stainless Steel for our Stainless Steel Barrels.
Our barrels are built on CNC equipment to completely machine the barrel. We drill, ream, rifle, turn, chamber ream, pin the Barrel Extension, drill the gas hole, and mill the flutes, all on late model CNC Equipment. There are 20 CNC machines in the Barrel Department, plus CMMs, in the lab. The Barrels are manufactured under the ISO 9002 Quality System, and each barrel goes through a Final Inspection before shipping.
The Military Specifications are just a starting point for the dimensions used.
Classic Firearms has sold thousands of these barrels and we fully endorse and stand behind them. They are fantastic.
