At a retail level, at least in my area, nothing is selling in any meaningful quantities.
ARs, in particular, are absolutely dead.
We've had almost half of the local gun shops fold up within the last year -- most of them since October. When people stopped buying guns, they also stopped buying ammo, holsters, slings, gun cases, extra barrels, magazines, etc...
The only things keeping my preferred LGS in business right now are:
1. Using Gunbroker to part out his stockpile of "junk" guns that he had stored in the back room.
1.a. GB consignments for customers that don't want to set up a seller's account.
2. Transfers - primarily from people like me that find cheap crap on the internet, or have a friend make a crazy low offer to sell their old projects, because they want them to go to a good home.
Today, I did see a new Heritage Rough Rider get sold to another customer. That was the first new firearm sale that I have seen anywhere in town since ... December(?).
(I was trading a Cobra derringer for a Tacticooled-out H&R 58 .30-30 "long range sniper rifle".
