Why get an AR-15 skeletonized BCG? Reduced weight equals faster cycling and felt recoil to get you back on your target faster. Great for 3 gun competitions. We didn’t skimp on shoddy tool marks and rough finish like some of our competition (you know who we are talking about 😉 ). a standard BCG weights around 11.6 oz, we reduced 3 oz (that the same as your mil-spec stock buffer) Our QPQ nitrided finish will last longer with reduced wear and tear as well as making cleaning a snap. Our efforts here was to make a great quality skeletonized Bolt Carrier Group for a great price.
