How does a polymer AR lower receiver compare to the standard aluminum?
Mike Answered question August 28, 2022
Polymer Lower is the term given to describe a synthetic polymer material that is used as the lower receiver portion of an AR-15-style rifle. It is a lightweight and durable material that can be easily molded into the desired shape. Polymer Lowers are often chosen for their ease of use and because they do not corrode like traditional steel receivers.
