Description
This carrier is machined by Outerwild from Mil-Spec 8620 Steel with a Manganese Phosphate finish that provides long-lasting resistance to corrosion. The interior is hard chrome lined creating a mirror-like, exceptional finish that is trusted by seasoned shooters and depended on by experienced builders. Outerwild’s secret sauce for our favored BCGs is that they are 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.
