So, I bought a suppressor recently, and am going through the form 4. Steve (Cold Hand Arms) walked me through it and it seems easy enough. I decided that since I have to go to the Sheriffs office to get fingerprinted, I might as well SBR one of my lowers so I can get that 10.5 I have always wanted. Enter the Form 1. Here's my plan, I just need to know what steps are out of order and have a few additional questions. I have: ATF Form 1 ATF Form 4 4 passport photos Two checks for $200 each 4 FBI / ATF fingerprint cards (the ones with the ATF address on them) I am planning to go to the Sheriffs office tomorrow and get fingerprinted. After these 4 cards are filled out, I take them home and mail them off the ATF (separately, form 1 and form 4) with the check(s). After they receive them, they will contact the local Sheriff and have them sign them and send it a copy back to me. At that point I can pick up my suppressor (form 4), and I can also get my lower engraved properly and order a 10.5. Is this correct? or does the sheriffs office do more? Do I have to get it signed? etc... I need to know the flaws in this plan... hehe I read somewhere that the papers have to be "copied" as double sided? Is this still true?
