Magpul Original Equipment (MOE) is a high quality but economical solution for equipping your AR-15 pattern rifle. This carbine stock is designed for use with mil-spec sized buffer tubes. The streamlined A-frame design prevents snagging on clothing or equipment and shields the release latch to help prevent accidental collapse. A premium chrome-silicon spring is also used in the power lock mechanism to further prevent unwanted collapse. Included with the Mil-Spec model is a 0.30" rubber butt pad to provide a more solid shoulder mount, even with body armor or modular gear. Made in U.S.A.
