NICE what ya building? I was going to get paperwork to rebuild a 22 mag rifle that the barrel was damaged on in a theft, but for $200 for the stamp it wasnt cost effective to do so. I can get what I had in mind to do with it, off the shelf for the $200 I would have spent on the stamp. I was going to shorten it to 12" and build a costom stock to turn it into a silloette pistol, with some redfield reciever peep sights, but like I said, not cost efective. So I won't bother, I just junked it instead.
Now get busy,,,,, we need some more gun build posts here.
