At least 3 more AR lowers, 1 more upper receiver, spare bolt carriers and such. Lots of mags, ammo and reloading components.
I do intend to get a quality AK47, to go with my sks that takes ak mags. I have a lot of mags that I purchased when I had an ffl before the ban at under 4 bucks apiece, + 2, 75 round drums. Mags are cheap right now, so if you see a deal even on something you don't own, pick up a few for trading fodder. I bought 6 glock 20, 10mm mags for 15.00 apiece before the ban in the anticipation of buying one, then the ban hit. I later sold those mags for 65.00 apiece when the going rate was over 75.00, I'm not greedy, let the other guy make a buck as long as I got mine. Just like the under 4 buck AK mags, now going for 10-14 bucks, not a bad return on investment, I truly did buy a lot of them.

A wise man once told me, it's not how many guns you have, it's how much ammo you have for them. At that time I probably did not have more than a couple hundred rounds per gun, and less for my hunting rifles. You can bet that has sure changed.
