I’m looking at an SBR Uzi build myself but man this wait is killing me. I popped for a form 1 VZ-61 a month or so ago and swore after that I wouldn’t file until I saw some improvment. The worst is when it hits the FBI no one has answers, no one can speed it up, no one can find out why. It’s literally floating in space. Even BATFE answers the phone, returns your call, and spends time explaining things as best they can. The FBI just shuts the door on your face. That being said I’m most definitely not the only 12-13 month approval dude. Several of my buddies at the gun store I work at were 12-13+ months as well. One of our cop buddies who has never ever been in any trouble has had 2 stamps come back in 6 months.True, I was looking more into a IMI Uzi build which in that case to make it look correct you'd have to register the receiver first then install the 8" barrel.
