My LGS has started getting ARs back in stock. A few weeks ago they had a waiting list for anything in 5.56. The price for a DPMS Sportical is $999.
Ammo and reloading supplies for the more popular calibers are still sold out. Double-stack handguns are still sold out with a few exceptions. OTOH, I have recently seen an M&P and Sig 229 in the 'used' case and a Shield in the new case.
To a much greater extent than most mechanical devices, firearms are terribly unforgiving of any overconfidence, complacency or negligence.
