The patent

-pending Magpul ACS (Adaptable Carbine/Storage) – Commercial-Spec Model is a drop-in replacement butt-stock for AR15/M16 carbines using commercial-spec sized receiver extension tubes. A streamlined, anti-snag profile shields the release latch to prevent accidental activation and the extra-power lock mechanism uses a premium chrome-silicon spring to avert auto-collapse failure by resisting spring relaxation. Similar to the Magpul CTR™, the ACS also features a supplemental friction lock system that minimizes wobble* for enhanced weapon stability and accuracy. Dual, rear accessible, water-resistant battery storage tubes and an integral storage compartment in the butt of the stock provides multiple storage options. The ACS comes standard with a 0.30" thick rubber butt-pad which provides positive shoulder purchase to prevent slippage even with body armor or modular gear.

Made in U.S.A.


* Friction lock performance may vary depending on the receiver extension's dimensional tolerances.

Magpul Original Equipment (MOE) is a line of firearm accessories designed to provide a high-quality, economical alternative to standard weapon parts. The MOE line distinguishes itself with a simplified feature set, but maintains Magpul engineering and material quality.

The Magpul MOE Stock – Mil-Spec Model is a drop-in replacement butt-stock for AR15/M16 carbines using mil-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 extra-power lock mechanism uses a premium chrome-silicon spring to avert auto-collapse failure and maintains strength by resisting spring relaxation. The Mil-Spec Model includes a standard 0.30" rubber butt-pad which provides positive shoulder purchase to prevent slippage even with body armor or modular gear.
