I've been helping out with the end of year inventory the past couple of days. There's lots less to inventory than there was on 14 December 2012. You would think that the run on semi-automatic firearms, "high-capacity" magazines and such would be over. Heck, we don't have much of that stuff. But, no, it continues. People are taking one look at the bare walls and some are changing "direction" by purchasing ammunition for guns they do have or buying reloading components. Often, they walked in looking for one thing and decided that anything was better than nothing given what will happen (and they believe that severe restrictions WILL happen). The racks and cases are starting to go bare except for single-shot shotguns and bolt-action rifles. Many places are apparently completely out of .22 LR ammunition and so many customers we don't normally see are coming in search of rimfire ammo and surprised that we actually have some.
We are also located near a major manufacturer of the forgings used for AR-15 uppers and lowers. As we understand it they have gone back to full shifts on production of those products. We have also been told that the magazine manufacturers have stepped up production of magazine bodies in an attempt to fill their stocks before an actual ban takes place.
