Details & Specs

A multi-caliber, mil-spec, AR-15 Lower Receiver, manufactured in the USA from high-impact proprietary composite polymer. This state-of-the-art polymer allows for superior strength while weighing a mere 4.3 ounces. The AR1 eXtreme is by far the strongest composite polymer Lower on the market today. Comes with a lifetime warranty…and of course, it’s Proudly American, like all things FMK.

It's all backed by FMK's Lifetime Warranty

All FMK firearms and components are backed by a lifetime warranty against defects in material and workmanship (for the original owner). If you DO find a defect, FMK will either repair or replace the firearm or component at absolutely no cost to you. That's the mark of a company that believes in its products.
