I Bought mine in June 2020, still waiting for approval. I call ATF every few months, I’m told it takes about 7 months, I point out it has been 10. My dealer told me it has been 12 for most of his customers. Dreadful.
When i did my three seperately my wait was 9 months but was done under the previous President... now i'm sure it is 12 months maybe longer idk as probably many are rushing to get one now with a differing mentality in charge.
Sent early Aug
Check cashed mid Sept
Approved early Feb
Stamp arrived last week, don't know if it sat on a desk somewhere or the USPS lost it for 8 months
