I am very pleased with my SKS (chicom) modification, I purchased a Fiberforce monte carlo stock
($41 at Cabella's) It looks good, a bit heavy, but my accruacy really improved, like 50-75%. @ 50yd I am very close to 1". (previous about 3") I was using UMC FMJ 123gr. But then I shot the Wolf steel HP and they shot much better also. (now I shoot resting on a bag standing up from hood of truck) with a cheap 5x scope. so a really good shooter with benchrest could probabally do better.
BTW I read somewhere that swapping stocks was difficult, didn't try, so I was ordering guns from my gunsmith and asked him if he woud do it, he said yes, $20. When I picked up he said it was very difficult, and moaned and growned. but he is a strange duck anyway. Just my experience.
