Posted 15 May 2017 (edited) I have one parts set for the U.S. MK12 20mm automatic gun. The kit includes a NOS barrel, complete bolt assembly, new extra stripped bolt body, overlapping receiver sections, barrel nut, gas piston, buffer, and other parts shown. The receiver sections are from two different guns and overlap. The feeder was damaged during the demil, but could possibly be repaired or a Lahti magazine could be modified to feed the rounds (20X110mm). Also included are 300 NOS links. There is no muzzle attachment, or ammunition included. I dug out the literature I have on the guns and will include copies. Buyer pays shipping. If you are in MO, OK, or TX, I can possibly arrange for it to be dropped off if you are not in a hurry. Trades are possible, but cash is king. All NFA rules apply.
