I have been wanting to get a 7.62 x 39 upper for a while, I ordered the bbl & bolt from model 1 sales and the rest of the stuff from rock river. all the parts showed up today and I put it together. the only fly in the ointment is that the bbl threads are 1/2" x 36 tpi, so the flash hider won't fit. I was going to rethread the muzzle but decided to do it right and get another flash hider.
I can't wait till tomorrow to do a mag dump into the bullet trap to see what kind of flames come out the front!!
the next step will be to take the 16" 5.45 x 39 upper I have and whack the bbl and have a set of uppers for my shorty. I want to build a box to hold the spare uppers, mags, optics and other goodies that go with the gun.
