I'm not sure which stock I want to go with. How do the steel underfolders shoot? They seem awkward and kinda crappy, but they do look kind of cool. They look classic AK to me.

 

I'm building an AK from a flat in PA btw. I'm looking at 250-300 for a parts kit, some sort of flat for $30,then a barrel in the $150 ballpark.

Seeing as how it needs to be pinned to be legal in jersey, why not go classic Russian Red from Timbersmith?

Definitely agree with lunker...dealing with the lousy cheek weld etc is one thing if it could be functional...but if you want to shoot and enjoy the platform...I'd go solid stock wood or poly ..... But like they say fashion is pain..to each their own lol

Looks is everything.  Get the metal stock.  Looks way cooler though not comfortable to shoot.

I should have noted this is a PA rifle. Hence the flat. So I'm going to enjoy my bayo lug and flash hider and park it next to my M1 Carbine.

russian side folder win...

I am with vlad, side folder would be my choice.

Triangle sidefolder all the way. It will still be able to fold and the cheek weld is pretty good and it still gives you a nice look with folding action. Or you can go folding polymer stock like on an Arsenal.

 

The cheek weld on an underfolder sucks. Whoever said looks over comfort should probably rethink their opinion. If you're never going to shoot it and you really like an underfolder, then go for it. But if you're actually going to shoot it, I'd go in another direction.

 

Whatever you choose, make sure to research it because I know the rear trunnions vary from some of the folding/fixed stock models.

 

Also, don't forget about the few additional parts your missing in your list there.

Polymer side folder FTW....

SIDE FOLDER! with polymer modern furniture.

Underfolder:  Looks awesome, crappy to shoot. 
Standard stock:  Nothing special, awesome to shoot
Triangle folder:  Looks awesome, awesome to shoot.

Triangle wins.
