There are some Russian mounts for AK style rifles that are offset to the left. It was found a long time ago that this is NOT ideal, so nobody offers are mount for telescopic optics that is offset. You can mount a scope directly on top, but then have a red dot offset to the side. You need to have the scope itself directly over the bore line, or you can't accurately adjust windage or use horizontal holdovers.
Hitting a chest size target with a red dot at 200yds is easy with some practice, but it's a LOT easier with magnification. You definitely need a 2MOA dot to do it, though. Anything larger gets difficult.
