Proof research 300 norma 9 twist that measures just shy of 25" threaded 5/8x24 spun up by straight jacket armory. Comes with bolt and magazine so it is a full conversion kit. Special purpose rifles charges 2450 for this, I’m asking 1750 shipped for it. I have berger 215 factory ammo available as well if buyer is interested.
