Get ahold of rifle dynamics, they build a fantastic krink. Get on the saiga forum, they have a lot of ak info there.
I can't wait until I turn 21 so I can have RD build a krink for me, currently I'm saving for a RD production rifle
Some guys are doing form 1's on the draco pistols and turning them into sbr's, its a cheaper krink alternative. For RD to build one its heck of a wait and if my memory serves me correctly the RD krink builds go for 2500 bucks or more, you'd have to ask
