If the build comes together okay, they can be fine. I've had some. I actually still have a couple. But the plastic can stretch/tear/split when hammering in a roll pin. I know this, because I've had it happen. And then your $50-100 polymer lower evolves into a conversation piece about your poor taste. I've also seen some issues (other folks' builds) with mags either not releasing or locking up properly.
So I have a pretty limited level of experience, and yet have seen a high percentage of problems. I will never buy another polymer lower myself. They can in fact be fine
. But there are too many potential issues, and too many reasons to build on aluminum instead.
BTW- NFA is a better option than ATI in my opinion, but I've seen problems with each. The ATI poly lowers are actually finished nicer than NFA, but they're absolute junk. Neither makes sense when you can get outstanding aluminum lower for $90-180...including trendy name brands, fancy finishes, and billet.
