Market is soft right now for AK mags, i've been able to add some to my collection recently that two years ago would have been unaffordable.
Ammo prices are the main problem right now. AR's are cheap again, but 5.56 is not.
Everybody wants to make AK's now since the prices have steadily risen for the last 20 years, but the ammo is no longer affordable, so i'm guessing the price of AK's has about peaked, they'll have to get a lot cheaper if they want to sell a lot of them in the future + ammo price will need to fall as well.
