I guess that would depend on your definition of "decent". I've never had a side mount scope, but I'm sure you could zero it on target without the need for hold over. On an AK type rifle, I don't think a scope is even necessary. If I had to have some kind of optic on an AK rifle, it would more than likely be a 40mm red dot of some sort and should still be very effective out to 100yds. But I might search out some form of top mount system unless the AK was already fit with a side mounting system. Just my opinions.
