Saltwater Arms M16 Bolt Carrier Group—Billet Extractor, 5.56, Nickel Boron

Saltwater Arms M16 Nickel Boron Bolt Carrier Group is the perfect BCG for your next build. Saltwater Arms parent company, Outerwild 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. The nickel boron coating is applied by industry leading plater, WMD. The NiB-X coating offers a very slick surface that provides long-term reliability and corrosion resistance.
