Anyone is welcome to shoot anything I have for sale. I only have a couple of rules.
One, the time and place have to be convenient for me, not you.
and
Two, every round fired is on your dime.
I don't care if you want to shoot ten rounds or a hundred. If you don't like it, I'll take it home, clean it up, update the ad to reflect the new round count, and move on.
Knew there was a reason I liked ya.
I will add that on some (like I posted earlier) Guns a quick 5 shot trip is almost mandatory. My beloved Fal comes to mind. Some shoot and some do not. And there is not a thing a normal gunsmith can do to make it better.
