The MOE Stock – Commercial-Spec Model (Magpul Original Equipment) is a drop-in replacement buttstock for AR15/M4 carbines using commercial-spec sized receiver extension tubes. Designed for light, fast action the streamlined A-frame profile avoids snagging and shields the release latch to prevent accidental activation. The Commercial-Spec Model includes an extended 0.55" rubber butt-pad to provide positive shoulder purchase and accommodates the longer, slanted back common to most commercial-spec tubes.
NOTE: There are two basic sizes of M4 Carbine receiver extensions (buffer tubes): mil-spec and commercial-spec. If you have a mil-spec extension on your rifle, make sure to order the Mil-Spec MOE.
Specifications based on extended-length (slant-back) commercial-spec carbine receiver extension and may vary depending on tube manufacturer.
Optional Rubber Butt-Pad, 0.30" and Enhanced Rubber Butt-Pad, 0.70" may ONLY be used with the uncommon standard-length (flat-back) commercial-spec carbine receiver extensions.
