Hello, I am an Active Duty Soldier stationed at Fort Campbell, KY. I am currently filling out a Form 1, to create an SBR. I have everything filled out, I just need to know a few things. I am at stationed a Fort Campbell, KY but live in Clarksville, TN, which is right across the KY/TN state line. Which address do I put on the Form 1, and I'm assuming if I put address in Clarksville, TN on the Form 1, I will be visiting the Montgomery County Sheriff for him to sign off on the Form 1? Also, how will it work if I want to cross the state line to go shoot at a range in KY? Would I be better off just keeping the SBR in TN? Any and all help is appreciated. I tried searching for .MIL + NFA stuff, but came up short.
