This week Fro stopped out for some gunsmith work. The paperwork finally cleared on his full auto Uzi, and he needed my help to modify one of the barrels.
He bought an aftermarket 9mm barrel rather than adding suppressor threads to the hard-to-find OEM barrel. The quality isn't as good as the OEM piece, so it would jam occasionally.
I loaded it in the lathe and opened up the chamfer where the bullets enter the barrel. All fixed!
Then we all shot it!
I made a proper bowl on my stump out of .06" thick annealed aluminum.
More tucks around the edge to shrink it even further.
Finished. It's not perfect, but it's just a practice piece.
