JeffersonDarcy,
I had a WASR...and I had a lot of fun with it! I only sold it to get into a "non-ban" rifle. Mine DID NOT have a canted sight and get it sighted in was no issue...it shot with reasonable accuracy for a Romanian, was reliable and cheap enough to throw around.
The mag problem is very easy to fix and you can do it two ways. You can file a little off the mag release (where it contacts the mag) or you can take a little off the mags where they contact the mag release. JUST BE CAREFUL THAT YOU TAKE OFF THE MINIMUM THAT YOU NEED TO GET A GOOD FIT OR YOU'LL HAVE THE OPPOSITE PROBLEM...SLOPPY MAG FIT!
Yes the finish is rough...I think it's just black paint. I painted some old beater mags with high temperature flat black paint from the local hardware store, and it matched the rifle perfectly. I think you could just spray on high temp paint on the whole rifle if so inclined, but I never bothered.
The furniture varies on these rifles, so if that matters to you then don't buy one sight unseen (i.e. like having your FFL order one from SGN). However, if you look around you'll find one with decent wood.
For a beater, you can't beat a WASR...I had great fun cooking the cheap paint off the barrel!
