Outerwild Manufacturing produces our M16 BCG which is trusted by seasoned shooters and depended on by experienced builders. Our goal is to go above and beyond Mil-Spec expectations! Outerwild’s secret sauce: 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.
