Scopes and mounts for WASR

I been looking to upgrade my WASR-10/63 with a scope. I saw that Classic Arms have a scope/mount combine for $60! Do anyone have experience with side rail mounted scope? It’s a tactical scope? Will my accuracy improve significantly?

Thanks

if you wanna do it right, buy the PU scope, it's the ONLY one ACTUALLY made for ak's. I mean come on, the russians made it, and it's for a gun, you know it's good :D
