It is now about 16 weeks. Takes the ATF about 2-3 Weeks to cash your check than another 12-13 weeks to get your paper work out. I have heard it is getting longer. The number of class three transfers has gone up 4 fold since November 2008. I just ordered a YHM .308 QD suppressor and this is what the dealer told me to expect.
Also if any of you are interested, he had a couple full auto M16 lowers pre-86. He wanted a little more that 12k each. A bit steep for me but he said they are increasing in price very fast.
Sounds like the wait is really going up. My last transfer from last summer was 56 days total time. I have paperwork in now for another suppressor. It has been 2 weeks since I mailed it. As they say, the waiting is the hardest part.
I sent in the paperwork for my MG in early February, approved May 20th. And that was with the paperwork being sent back twice for errors. I am about to submit for a new silencer I just bought, we will see if the wait time is the same or longer -although I really think it depends on your examiner (I always try to be very polite to my examiner and it has paid off a couple of times).
