I've decided my next build is going to be a 300 blk sbr with a silencer. I've researched the process of getting a silencer but I want to have it pinned to the barrel. That way I can buy one stamp. Can someone direct me to a gunsmith that can pin it to the barrel? I also need an attorney that specializes in nfa trusts. I may end up just getting two stamps but I want to at least talk to a gunsmith about it first. Thanks as always for your help!
