Any Tips for 80% Lower Buffer tube Hole?
I have one of these I got from tannery shop, I also have his Tappered Reamer bit and the Monster Tap but have not attempeted to work on it yet.
I have built ARs from 100% lowers and AKs from kits so I have some different experience just not an 80% Lower.
I also have the drilling jig and the bits for those and the tap for the pistol grip but those don't scare me much.
So guys any tips on doing the buffer hole and threads?
I know it has to be straight and centered to work correctly, how do you guys accomplish that?
