That information coincides with another major rifle forum's information.
It appears as though stamps are coming back from 3/6-3/10ish.
Unfortunately, approval times seem to be continually creeping up. I wonder where or when that trend will stop and potentially reverse. I don't see that happening anytime soon. The ATF's hopeful projection that they would be at a 90 day approval period by the end of 2023 seems to be fanciful thinking.
I have a late July submission i'm waiting on and i'm crossing my fingers I'm at least still in a time frame where a seven month approval appears to be a thing.
