Process to legally make your short shotgun legal
Step #1 Get a Form 1 (in duplicate) and two fingerprint cards and two 2x2" Passport Photos
Step #2 Have your local chief of police or Sheriff sign the back of your completed Form 1
Step #3 Mail your completed forms, signed by your local Chief Law Enforcement Officer, your two fingerprint cards and two photos to the ATF with a US Postal Money Order for $200.00
Step #4 While you are waiting on your approved stamp, send your receiver to an engraver and have your FULL NAME, CITY and STATE Engraved on it, you will have to have the location of this engraving listed on your FORM 1
Step #5 Wait for the approved stamp, 90 days to 12 months, depending on ATF
Just a Tip, An UNREGISTERED Short Barrel Shotgun or Rifle or ANY unregistered NFA weapon will get you an Automatic Ten Year Jail Sentence and a $250,000 fine. DO NOT LOOSE YOUR RIGHTS by not paying the fee and doing the right thing. The Tax is a one time tax and thats it, NO CLASS 3 License is required, no FFL is required, you can do it yourself.
SO DO NOT ASSEMBLE OR HAVE PARTS IN SAME LOCATION UNTIL FORM IS APPROVED
A Good Engraver to use, who is reputable and cheap and quick turn around :
(It cost me $60.00 shipped to have my 870 SBS engraved)
