White Label’s parent company, DRG 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! White Label Armory’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, giving our BCGs a near frictionless surface finish. To ensure long-term reliability and corrosion resistance, WLA 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!
