Description

Introducing the Outerwild M16 Nickel Boron Bolt Carrier Group — this is the perfect BCG for your next build, easy maintenance meets reliability and good looks! Our M16 BCGs are trusted by seasoned shooters and depended on by experienced builders. Our goal is to go above and beyond Mil-Spec expectations! Our 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. The nickel boron coating is applied by industry leading plater, WMD. The NiB-X coating offers a very slick surface that gives the shooter long-term reliability combined with resistance to corrosion even in the harshest environments.
