I have a WASR-10 that is a good rifle. Canted gas tubes and canted sight blocks are common on these rifles, so look carefully to be sure you get a good one. As long as you keep in mind that the AK is not a match rifle you should be pleased. They are utterly reliable; mags, ammo and parts are both cheap and plentiful; recoil is low; and accuracy is usually between 2 to 4 MOA at 100 yards.
If you are not familiar with the AK series of rifles, the butt will seem a little short but once you get used to it it's no big deal.
