So lets make it easy on OS. We all send our money orders/checks and a self address stamped envelope. He makes no commitment to order until he has 40. He doesn't get 40 he puts your payment back in your envelope and mails it back. This is if he is willing to do it.
I was in the same boat as you. Guy who works at my local range offered to meet me on his day off and brought 3 different ones with him. Bought myself a mak-90 off of here less then a week later.
