Mike S.'s Review of Hughes Ballistics 5.56 HB Pro/M16 Bolt Carrier Group (BCG), Nitrided

The bolt on my BCG started chipping on the back of the lugs. When first installed, it head-spaced within tolerance. Rechecked the headspace when I noticed the chipping and a FIELD gauge would easily drop in. Bolt lugs measured .250" specs should be .278-.280" Bolt face recess measured .125", which is at the max for depth.
