I have a couple of questions for folks that really know about rifles that use the 7.62x39 ammo. I own a sks and love it and I'm thinking about increasing the accuracy so 1) Would installing a scope accomplish this? suggestions! 2) I know there are other bolt action makes of this caliber cz,ruger,remmington are there any others and can you comment on the actual use to it's accuracy and reliability at 100yds.
