As said above, everything AK went up (as well as everything "black" or semi-auto really). BUT IMO SLR-101's were under-priced in the first place, at least compared to any other milled AK going currently.
When was the last time anyone can remember seeing a Milled Pre-Ban AK for under a grand? Uh, not in years right... Shit the nearest comparison is the SA-M7 which was already $1600 and not built on a true Bulgarian receiver like a 101.
I was honestly really surprised to see the 101's priced at as grand in the first place. I wish I'd bought more than the one I did buy... I said to myself "self, this is an insane deal and you will probably regret not buying at least 5 of these". I was right, and I wish I'd bought as many as I had money for at the time for $949!
One of my LGS just told me they had one coming in next week for $1159 and that I could put money down to hold it if I wanted to. It hurt doing it knowing that 6 weeks ago I could have nailed another one (or 5) for a couple hundred less /ea, but what are you gonna do? I wasn't gonna piss and moan over a couple hundred more bucks when there's a real good chance there won't be any more of them anywhere near that price, or for any price at all.
Milled Bulgy's are just too nice not to have a few. I've got an SA-93, SLR-95, and the SLR-101S and love them all so much!
