It turns out that the $800 AK I saw was actually a completely fair price for that version and I should have bought it.
Today I ran across a Mini 14 and some fancy pants piston AR-10 type thing.
The Mini was $1600. The AR-10 thing was $3500.
I passed on both.
Yes, $800 is a very fair price for an AK right now. Most of them go for $1k + even for the lower-end AK's.
I got lucky and bought a Draco AK last week for $700 with 2mags. I don't consider it a panic buy as I've always wanted an AK47, and it was still a very good price considering the whole frenzy.
