The operations this jig covers are as follows:
Drill Barrel Hole
Drill and Tap Barrel Clamp holes
Drill Bolt Stop
Drill Trigger Assembly holes
Drill and Tap Stock retention hole
Cleaning Rod Hole (optional)
While the tasks are easier to complete with the 80% TM-22 it is extremely critical that the jig and your drill press is level. Do not remove the jig in between operations on the side you're currently working from. This is especially important for the barrel & barrel clamp holes. They must be precisely placed. Also, do not drill all the way through the receiver on he bolt stop & trigger assembly, these are required to be flipped as the drill will walk.

You will also need to find a long drill for the charging handle retainer or use a sharpened punch. We recommend sharpening a long punch and hitting it through the barrel hole.
