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 friction-less surface finish. To ensure long-term reliability and corrosion resistance, Outerwild partners with industry-leading finisher: H&M. Their Blacknitride+™ finish delivers the utmost durability and improved lubricity for our BEST-IN-CLASS BCG that is 100% American Made!

Quality Bolt
These are good quality bcg's. I've run quite a few of them across many rifles with zero issues. Highly recommend, especially for the price.
