I just got a stamp back 368 days from when i filled my last paper form on July 12 to sbr a Yankee hill lower.  A couple days prior i got a request to fix my form because i put scorpion evo s1 instead of cz scorpion evo s1 that i submitted same day with the other lower.

My suppressors took an avg of 10 months.
So from last year to now i got:
Aac tirant 45
Gemtech mist 22
Griffin recce 7
Aac 556sd
Griffin rev 9mm
Sbr'd axts lower, 2 aero lowers, yankee hill billet lower, and cz scorpion.

This is horse $4!+! They did a defacto ban on NFA items overnight by refusing to approve forms.

See above.
