I submitted 3 form 4's on 01/05, one on 1/12 and the last one on 1/16. All are but 1 are going on the same trust, and none have been approved yet. On the reddit NFA thread it seems like several are getting approved in less than 10 days. Curious if my late additions have slowed the process down for me or if there is no rhyme or reason on how the ATF approves things.
