Well, my technical question has certainly generated a lot of heat. I have long enjoyed the insights and comeraderie shared on this forum. I have asked questions about gunsmithing and learned a lot. When I have known the answer to questions, I have shared them. This is what I think the forum is about. Actually, I expected a short reply telling me how to make a modification. One good answer I think I got was to change out the reciever.
Thank you very much for your replies, ideas and suggestions. I know they are well meant and I know from the past that responses from most of you are well worth reading.
Insults are never welcome. Maybe I got oversensive, but nobody ever thought that before, and there is absolutely no need for any insults to a true American hero you don't know, suggestions that this question is an effort to violate some law or regulation, or especially the wisecracks implying lack of honesty or criminal intent in the qustions or lack of character in the persons asking. A friend wrote asking me asking a question I didn't know about, and I honored you by bringing the question here. If you are offended by my question, please just don't reply. I know these days most have lost respect for the best men, but I have come to expect better here. I had hoped to just copy and forward the replies I got here, but obviously I won't do that now.
I've been bogged down in enforcing federal law and regulations for decades, and know how time consuming it is to personally research into an unfamiliar area. Really good info from agents can be mighty hard to get. So I ask and appreciate informed replys to these informal questions. I would never proceed without the acutal rule in hand and discussion with the authorities, no matter what I think of them. I did spend a while today researching the regs and the law on this subject, and was appreciative of the accurate info I got from some of you. We don't have to be right but it would be nice if we would be...well,...nice. I promise not to bash your questions even if I do know all there ever was to know about it, am seven feet tall and bullet proof. I won't insult you either.
The IRS regs in the National Firearms Act are pretty simple (Yep, IRS rules, mainly due to the original tax purposes I guess). Less easy to find was that you don't have to be an importer to import a firearm, and there are provisions for a soldier to import weapons even to his own address (not surplus). The cite for the 1986 rule accurately referenced by oldcspsarge is Title 27CFR, 479.105 in case anybody else wants to read it.
