How does a polymer AR lower receiver compare to the standard aluminum?
A polymer lower is a type of firearm receiver that is made from a polymer material, as opposed to the traditional aluminum alloy. Polymer lowers are generally considered to be weaker than their metal counterparts, but they are also significantly cheaper and easier to manufacture. As a result, polymer receivers have become increasingly popular in recent years, especially among budget-conscious shooters.
Polymer lowers can be found in a variety of different colors and styles, and they are often marketed as being “drop-in” replacements for traditional metal receivers. However, it is important to note that not all firearms are compatible with polymer lowers, so please check with your manufacturer before making any changes. Thanks for reading!
