The SAR's, not the WASR's, were the ones that were the base for most of the canted sights and trigger slap complaints. Ive seen some that had some really bad canted front sights, and shot a couple that had terrible trigger slap.
Mine had a little of both, although I only ever corrected the slap, with a RSA replacement trigger. The sights while canted, really arent canted that bad, and it dont seem to affect accuracy.
If you do find yours has trigger slap, Red Star Arms makes a great replacement trigger. Its fully adjustable, and equal to and actually surpasses a "real" AK trigger. Unlike most AR's, AK's triggers are usually pretty nice, and even the ones with slap. They are painful to shoot with, but still way better than the average AR trigger.
I did try a Tapco G2 trigger on my WASR after hearing all the great reports. I must have got a bad one, as it was crunchy as all get out, and was actually unsafe. If you started to pull it back but didnt let it go, it would hang in that spot like a set trigger, and go off at the slightest touch the next time you put your finger near it.
Fit and finish on most SAR's Ive seen wasnt all that good, and my WASR, which is an early one, and looks like a SAR, was much better in pretty much all respects, including sights and trigger. The only real difference in overall appearance, is the WASR's lack of "dimples", and obvious "cut out" mag well. Most of the makers info on my SAR was "carved" (literally) into the metal with what looks like some sort of engraving pen in the hands of Katherine Hepburn. You can barely read what it says.
Accuracy and function wise, they both shoot great. Both have been accurate and reliable from day one, something I havent been able to say about some of the fancier, US made/assembled AK's Ive owned.
This is what my SAR looks like these days.....
And this is how it shoots at 200 yards (from a cross legged sitting position) using the "canted" irons, with ammo it likes........
