Hello, anyone have experience with an 80% AR lower build? thinking maybe polymer but no Idea at all of how they hold up. Suggestions please.

I’ve not built any but my preference would not be polymer. Can’t give you a good reason why as I have no experience with poly AR15 lowers but just preference.

Polymer lowers have been proven to
break under force such as a simple drop.
It’s not that polymer is bad but the weight of the components puts too much stress on the part.

A WWSD 2020 monolithic polymer lower may obviate that issue, but they aren't 80%.

I have poly upper and lower, but not 80% type. I've had it for 4 years and no issues with it! I haven't done any 80% at all, so no comment about those.
