AR15 Bolt Carrier Groups

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! The Outerwild 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.

Proudly manufactured in America!
