I read it here somewhere, but I cant fnd it now. What is the procedure to making and verifing and registering a firearm? I have my pol, do I need a pal instead? Does anyone know where to find the details on what the exact rules are on home builds? I was seriously cosidering a .50 bmg single shot, like the one being built by the boys on this site. That gun makes my crotch swell a little. And my wife said " I think it would be a good investment....."; no ####, she really did. God bless her.
