Do polymer lowers break?
The biggest question people have with polymer AR lowers isn’t usually the fit of the product, it’s the durability. If a polymer lower was going to fail, it would be there. While the recoil of a . 223 Rem/5.56 NATO is minimal, that part of the lower still bears a significant physical load.
