What does one need to do to buy a full auto gun(select fire Ar mainly) I know you fill out some paper work and give the ATF a good chunk of change, but what else? DETAIL DETAILS

About $12,000+ for the gun, $200 for the tax stamp, and fill out the appropriate paper work.

I believe you also have to get the local approval of a law enforcement member, perhaps Sheriff or Police Chief??
As I understand it. Since the amnesty by the Government some years ago, all the old unlicensed fully auto military firearms turned in were issued papers, declaring them legal after the proper licensing,. Every used full auto firearm MUST have papers or is automatically illegal and my understanding is there is no way for it ever to be made legal by the Gov. This of course has caused the prices to increase greatly. Of course, you can probably buy a new one, licensing and such. Limited supply always forces prices up.
But, this has not stopped collectors from buying, only becomming more selective. I understand a papered GOV WW II Bar was presently on sale for $36,000, in very good condition. WOW. Can see how I screwed up again by not collecting the full auto military after the war. For those who did, now have a very tidy retirement sum.. But only being 8 years old.

Find the gun you want. You'll need to have the transaction done through a properly licensed dealer too. he'll be able to guide you but it's pretty simple. You'll need information about the firearm on your forms and an approval from the chief law enforcement officer in your area. That along with finger prints and the $200 are sent with the completed forms to the ATF. Upon the return of the tax stamp, you pay the dealer and it's yours.
Remember, to think ahead. Once you sign and accept the gun, you have that money tied up and not easily liquidated back into $ unless you take a large loss. Feeding one isn't cheap so plan for the expense of ammo as well. Also, make sure you have a place to shoot it. Many ranges don't allow them so unless you plan to buy it and not use it, make sure you have a spot to shoot it.
