I contacted my congressional rep and had their office contact the ATF and FBI. My background check with the FBI was completed a day after contact and then suppressor in hand a week later.
I believe I'd still be waiting if I hadn't reached out to my rep.
Hey brother, it's been a long time! Hope all is well!
I just went that same route yesterday after 155 days of waiting on my eForm 1 to be approved for my AR pistol.
I got a quick reply from Tony Gonzales' office and sent them the necessary paperwork to look into my case.
Given the average turnaround for eForm 1s is 45 days according to the ATF, there is no reason whatsoever for a delay in processing and approving my application.
Time will tell if my case worker is able to clear the log jam!
