The BCG showed up quick. It appears to be made to spec. Staking was done correctly. I have only run about 40 rounds of 300 BLK ,20 sub and 20,supersonic. then pulled it out of that rifle and ran a hundred or so .556 through another rifle on the one BCG. It head spaced perfect and ran great for those few rounds. I bought two BCGs, one for each rifle, and lost one somewhere around the house.
