PRECISION GROUND. We machine and grind our BCGs to perform for tens of thousands of rounds. We grind the outside dimensions and ALL three interior dimensions of our carrier, giving our BCGs a near frictionless surface finish. The polished nickel boron coating is applied by the industry leading plater, WMD. The NiB-X coating provides a very slick surface that makes for easier cleaning and increases reliability. Properly built, no corners cut.
