I have a new Molot vepr (unmodified) and put a Texas Dogleg scope mount on it. The gun with dogleg mounted peep site will group 1/2" all day with Wolf at 25yrds. Mount is solid. It will group 1" or 1.5" at 50 yrds (5 shot groups). My CAI and Saiga (both iron sites) will do the same with wolf at those ranges. I wear bifocals so thats my limit. I put cheap necstar scope on it (2x7) and at 100 yrds, 1st shot is 5" lo and it climbs until 5th shot 4-5" high. Horizontal is good never more then 1.5" either side.Scope locktited and like 25th one I,ve mounted.I have had different shooters get same results. I have eliminated all the variables but gun and scope. So here is the rub, couple guys at range tell me there Aks shoot fine until warm/ hot then groups climb like 5"-7". I know and have heard of POI changeing after gun hot but 5"-9" at 100yrds? Anybody ever hear that AKs in particular really change radically more then bolt actions etc when hot? Is it just a shit scope or is AK more heat sensitive then most rifles.
