PLA small arms go through an exhaustive torture test in various simulated environments, possibly harsher testing than used by other militaries and private companies. So rifle reliability, since at least the Type 81, have been very good.Alright, this may be a bit weird to say but:
Outside of the bad coatings thing, I barely see any reports of the QBZ-191 functioning badly, which is good.
Granted, almost every modern day rifles function fine, but the QBZ-191 doesn't suffer from the rust(?) and zeroing issues of the AK-12 (So far at least) and doesn't have things like weight complaints or whatnot like the XM7.
As generic as it is, it's a pretty fucking good rifle all and all.
