Outerwild M16/AR15 Bolt Carrier Group—Billet Extractor, 5.56, Nitride

INTRODUCING OUTERWILD’S Custom M16 BCG manufactured and assembled in house in Lake Zurich, Illinois. All our BCGs are PRECISION GROUND—they are machined and ground to perform for tens of thousands of rounds. We grind the outside dimensions and ALL three interior dimensions of our carrier, giving these 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, 10 times stronger than it was originally with improved lubricity. All this delivers our BEST-IN-CLASS BCG that is 100% American Made! Trusted by seasoned shooters and depended on by experienced builders, Outerwild’s complete bolt carrier group goes above and beyond Mil-Spec expectations!
