At our shop here in Jacksonville NC we have had approvals come back in as little as two days... Had one form 4 I submitted for a customer on a Saturday afternoon approved and being picked up by a customer at 1200 on Monday when we opened again. We do your entire NFA process in about 20 minutes in shop from the time you point at the can in the case and say I want that one to you walking out the door with a receipt, your form 4 submitted and fingerprints in the mail. We roll the prints at the shop and do your passport photos for the e-file while you are in shop.
We are currently doing about 8 to 10 NFA items a day from the shop, not including silencer shop transfers, which are honestly a huge pain in the ass for us anymore.
Our biggest issue right now is getting more cans into the shop from the distributors. The shortage of suppressors and the stuff to make them is going to become the problem now. We have already seen a dealer price increase on a bunch of stuff and watched some distributors decide that they are only selling stuff at retail or right near it right now. We will keep that in mind next sales downturn when you are blowing up our phone begging us to buy from you... just saying...But the shortage is real, if a place has the one you want, jump on it because we/they are probably gonna struggle to get another one in at this point for a bit. We currently have orders out for about 90k worth of cans, not sure when they are all going to arrive.
