SP4™ Extreme Wear Coating Technology is here! White Label’s parent company, Outerwild produces thousands of M16 BCGs which are 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: WE PRECISION GRIND. We machine and grind our BCGs to perform for tens of thousands of rounds. We grind the outside dimensions, and ALL three interior dimensions. The Extreme Wear Coating technology, SP4™ is applied to the bolt carrier, bolt, firing pin, gas key, cam pin, extractor, and gas rings. This thin film has the thickness of three (3) microns and a hardness of 3,000 on the Vickers scale. SP4™ advanced surface engineering capability reduces friction, improves wear resistance, increases reliability and is corrosion resistant while extending the life cycle of critical components.
Our BCGs with SP4™ Extreme Wear Coating are Polished to a Mirror-Like Finish and are #1 in Hardness, #1 in Flexibility and Elasticity and #1 in Low Coefficient of Friction (.01)
