Very nice. Did the bolt pick up some color from the Moly? Only thing I do differently is use steel filings instead of micro balloons for anything around the recoil lug but shouldn't make any difference on the pillar as it shouldn't be a point of recoil contact. Did you use epoxy or Bondo for the checkering?
