i just finished mounting a scope on my sks today. this is my very first gun and my favorite! over the years ive had about a half a dozen different scopes & mounts. all have eather a poor fit, rattled loose, or were just a pain to deal with.. so i desided to go with a psop scope and a side mounted rail. i havent taken it out yet, but it already it seems much more rigid than the cover mounts. i like the military recitcle and rangefinder. i am a little sad i cant use stripper clips anymore. in case anybody is wondering, its a 1954 russian sks; with a 8x42 posp scope.
