I was there as well today, and they did have plenty of staff, and the place is pretty much fully stocked. Wide seclection of handguns, rifles and AR's. They are taking steps to keep the customers happy, instead of creating ways to make the customers rich
For AR's they are limiting one firearm per person (which is allowing them to be in stock, what a great idea). They do have p-mags and .223 ammo in stock, the catch is you need to purchase a firearm to get them. When you purchase a firmarm, you are also allowed to purchase up to 4 p-mags and 1000 rounds of ammo. A very well run place, and I was happy to walk out with a AR.
I also stopped by the gander across the street and was able to get a case of 1600 rounds of CCI .22LR HV. This was the last case (as I purchased two additional cases yesterday at gander when I bought myself a pistol). They do still have about 6 cases of 1600 round cases of .22LR HP and at least 10 cases of 500 round .17 HMR.
