need a good scope mount   wich one and where to buy

That all depends on what you want to do with it and how much you're willing to spend.

For a normal rifle scope, you could get a Belarus BP-01 and still use you iron sights:  BP-01

Or you could spend a lot more and get a KVAR mount:   KVAR's mounts


If you're mounting a red-dot or you want a low mount, you could get a BP-02:  BP-02

or if you're not afraid to do a little work , you could get an Ultimak: Ultimak,


As for places to order, I've personally ordered from Freedom Optics and Ultimak.
But finally, don't forget to check the EE under Optics & Sight Equipment  and  AK Mags, Parts & Accessories.

thank for the help
