I was trying to make it simple as possible there are two forms. First is a form 1 that is what you fill out to personally make an NFA weapon except MG's they are banned for us to make. Then there is a Form 4 which is what you fill out to transfer an already existing NFA weapon to yourself.
Both forms require the same process there is no difference as far as your end go's. If you purchase something from somebody out of state then you have to have a dealer like Alan transfer it in state then form 4 it to you.
The best thing for you to do is decide what you want and when your ready there is plenty of us here that can walk you through it. We have Ryan, Karl, Me, Alan, MP5, Muzzleflash and Richard just to name a few.
