This is how I roll with my stuff. I have been able to buy some nice toys, including full-auto guns and a Barrett Light.50. I will never tell some one they can't try out something because they don't have $$ or something I want to shoot. If you see something you want to shoot, ask with what you think is a fair deal, and see what happens. A full-auto M-16 is a 10-15k gun, so for me (or any one) to not be able to share a mag is BS. HOWEVER, one day, some one my want to try your toy (we have all been there) so be ready to share. Pay it forward, especially if there are kids.
