I've got a stripped lower that I need to assemble and I know that I can get by almost anything under the sun to assemble it. However this lower has a tax stamp with it so I want to make damn sure I don't break anything when assembling the trigger guard. This isn't the first lower I've assembled but since doing the first lower I have lost the punches I used.

What punches, roll pin holders, and roll pin pusher do you recommend. I'm positive I'll be building more than this one lower so I want something that will last.
