A REVIEW OF BCM LOWER

bcn complete lowerAppeared it more than so over and over and will't locate the blem. Everytime I think I locate a little something off, it is just oil smudges. Greatest guess at this time is scuffs on castle nut, or The 2 little silver places during the flare from the magwell. 1mm dots at most. BCM QC isn't going to mess all around It appears.World
