The tax stamp / license is very difficult to get, or so I've heard. It's not like the ATF 4 form, for purchasing a silencer, that I've seen at many gun stores.
no, it’s the exact same process as buying a silencer. fill out form 4 send $200 and wait
They're both classified as Class III weapons and the stamp process is the same for both the silencer and the auto rifle.
I recently took possession of my first silencer. It took over five months from the time I first applied for the stamp until the silencer finally arrived in the mail.
Finger prints, passport photo, ATF forms, approval from local law enforcement.....
The merchant I purchased it thru was great. They guided you thru the whole process, providing links to the govt. and sending you the finger print kits.
