Hi,
I am looking into purchasing a sound suppressor for my ar-15, and I am unclear on what forms i need to submit to be permitted to do so.
A buddy of mine said he had to get a class 3 permit for his p22, but from what I have read you do not need to do that.
Just looking for some insight, I’m quiet confused on the situation. Don’t really want the wife to find out how much money I will be spending on this either. 
Do I need to submit forms 1 and 4, or just 4?
Thanks,
Mark
There’s no such thing as a Class III permit.
Because it’s a lot to type:

I think he was saying that his friend got a Class3/SOT License?
Which thre is such a thing. This was pulled from the link you posted:
“NFA weapons are also sometimes called class 3
weapons, because a class 3 SOT (see below) is needed to deal in NFA
weapons.”
and
“The classes of SOT holders:
Class
1 - importer of NFA firearms
2 - manufacturer of NFA firearms
3 - dealer in NFA firearms”
That would be a pretty long and expensive process for someone, just to own a few NFA items.
BTW, thanks for the link, I didn’t have that one. Do you mind if I use it on a another forum also?
It’s not my website I just found it a long time ago.
Many people think that you get some kind of permit/license to own NFA items. There is no license to own, licenses are for FFL dealers to sell/transfer NFA items. NFA items are taxed (one time) to own, the recipient pays the tax. You’ll use a Form 4 to transfer an existing NFA item from a dealer or individual. If you want to manufacturer your own NFA item (i.e. short barreled rifle) then you would submit a Form 1 and once approved (you’ll get one of the Form 1s back which will have your tax stamp on it) and then you could manufacturer it.
Only licensed FFL (Title 1) dealers pay an additional tax (SOT) to become NFA licensed manufactures or NFA dealers.
Acquiring a NFA item isn’t like getting a permit to carry a handgun.
