I had AKs. I have an SA vz-58. It is much better, lighter, more accurate than the AKM clones I had, and just plain fun to shoot.
The vz-58 can be had from Czechpoint in either military original with the world famous beaver barf stock, Sporter or folding stock military, 10 round or 30 round capable.http://www.czechpoint-usa.com/products/rifles/762-x-39-mm/
They are listed out of stock on everything right now, but catching up. Magazines are not really expensive, and Czechpoint carries a LOT of accessories! Czechpoint is also the place to go for the side mount for the rear short rail optics rail, seen here on my wife's SA vz-58 5.56mm with AR magwell adapter,
I prefer the forward mounted red dot look myself on my SA vz-58 7.62x39mm, using FAB forearm, pistol grip and folding stock, all available at Czechpoint - surf through the Spare Parts section. Current optic is the well thought of Bushnell TRS-25, seems to work quite well,

$15 for 922 compliant mags. Not bad at all. LOTS of spare parts available that I've so far not needed, the rifle just keeps on going and going...
It will do what you want - here is a B-27 silhouette target shot at 200 yards, EOTech 1X red dot sight, not rested.
Shot like this,
I highly recommend the Israeli patrol sling, very nice item. I haven't been out to do this in a while - either bad wind or nobody I can trust to gear guard whilst I trudge downrange that far.
Other than that, the only non AK 7.62x39mm rifle would be the elusive Valmet, high dollar sporter, the Saiga, which is, of course, and AK with a slightly different look, the Century vz-2008, which, as noted above, seems to be the exception to the rule of Century made rifles are junk. Most members here with vz-2008s are very happy with them. All Czechpoint mags will fit Century vz-2008 rifles.
If you are willing to go bolt action, the CZ 527M 7.62x39mm carbine is unbeatable for a light rifle - LOVE mine.
