Got a tracking number for the AK pistol (finally). Should be at Freakshows tomorrow. I will try to call him again tomorrow. Seems there is some concern, from another calgunner, as to how exactly he will convert it to a single shot. From what I have gathered he will remove gas piston, pin a mag to one round, and put a mag lock on it.
Don't know exactly if he is going to block the gas tube somehow. Don't know if it is really necessary.
