Should You Buy a Polymer AR15 Lower | Polymer VS Aluminum Lower Receiver Test | We Break Stuff Again
This video tests the durability of polymer AR-15 lower receivers against an aluminum counterpart. The primary failure point identified for polymer lowers is the threaded buffer tube receiver area, which can strip or crack under stress. While polymer lowers are significantly cheaper, the testing demonstrates a substantial compromise in robustness compared to aluminum receivers, making them unsuitable for demanding use or abuse.
