Everything looked good 'till that last pic - bummer! Probably won't make you feel any better, but I have a small (but growing) collection of "NFG" parts, too!

With the extra volume from boring, you more than likely will need a stronger hammer spring (or a stock spring with RVA turned in a bit) to take advantage of the larger volume of air you are trying to dump.

Good luck! Keep us posted,
