What success have you had with Yugoslavia SKS stocks
I agree, our Chinese Type 56, Russian SKS45 and Yugo 59/66A1 all are in original wood and we have never considered changing to anything ese. My Yugoslavian SKS is as heavy as a Garand but I'll deal with it.In my opinion you spend $$$ on a replacement stock that most likely will perform poorly, there are ATI, Choate, etc all are equally lousy. Your Yugo stock is a dense wood and it has a rubber butt bumper and properly inlet, the fit and finish on the inletting is excellent, they are longer(slightly) than most SKS stocks and rugged as heck. They offer a good cheek weld for iron sights; if you plan on using a scope there are alternatives..
Polymer stocks on SKSs suck, they do not tend to offer a good barrel/action fit tightness and most likely will need to be fit. Save your $ and buy more ammo! The stock you have unless messed up will work fine..
