Rise armament bcg - RISE Armament AR-15 Bolt Carrier Group (BCG)

The Rise Armament bolt carrier group is a farley good bolt carrier group but truthfully I expected it to be of better quality. The finish was really nice and it looks great but the three bore tolerances were loose as a goose making the gas system not as efficient as it should be. Remember this is only one example and doesn't necessarily mean that they are all this loose in the three bore tolerances.
