I saw an adapter that allows the use of an AR stock on an AK rifle. I just do not remember where i saw it now. I'm pondering going that direction on my AK. I'm wanting to shorten the length of pull, but I do not like the OEM style AK stocks. I was thinking along the lines of a 6 position AR stock. My question is, do the adapters work, if so how well? Also where can you buy them, and are they stock specific?
