I may not have. I don't even know what a SBR permit is. What is it?
Oh, just googles "SBR" permit and it looks as tho it's an abbreviation to legally allow purchase and ownership of one suppressor.
You better believe I did. Since I own a corporation I didn't have to get fingerprinted in Georgia nor did I have to get a letter from the local Sheriff. Just $200 stamp, forms filled, and 2 month wait.
I enjoy the suppressor a lot. I wish I could buy another for a .35 cal barrel. I've also tried to get a permit for use of a suppressor on coyotes. The local warden for my county said he did not know of one [but there could be] but he understood why one would like to use one for coyote control. I own an exterminating company and am often asked about coyote control. Trapping is the recommended service and I sub it out.
I have found that some rare 'permits' can be aquired for pest control. I once had a Federal permit to kill morning dove out of season in an aircraft hangar. I don't remember exactly but it was for either 24 or 48 HOURS. I had to report any leg bands, number killed, etc. The Federal USDA animal control division can get some 'odd and rare' permits if a need arises! The Fed USDA employee I know gets to do deer kills on airports, and islands off the coast of GA and other SE states.
I operate LEGALLY.
