I want something that I can use a normal cheek weld with.
Also, I would like things to be as centered as possible on the rifle.

RS Regulate is the best US mount hands down

Here are a few other options http://russianoptics.net/mounts.html

Stay away from UTG

I'm very pleased with my RS Regulate mount and trijicon ta50.

However I think you should expect a slight chin weld unless you change your stock or use something like a stock pack.
It's not horrible, but you can't get on the stock like you do with iron sights.

I read a few people mentioning Ultimak and the Attero Arms mount are cowitnessed and the lowest possible right now.
Also saw the new Aimpoint shotgun sight from Vickers Tactical on youtube, I really hope someone adapts that to an AK like the Attero mount, looks perfect.
