Magpul CTR Carbine Mil-Spec AR15 Stock


The Magpul CTR Stock (Compact/Type Restricted) 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 CTR also features a supplemental friction lock system that minimizes wobble* for enhanced weapon stability and accuracy. 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.

Made in U.S.A.

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

    Definitely a step up from a standard M4 stock. Nice and solid when locked and still very sleek

    I love this stock, and it's the only one I'm aware of that limbsaver makes a recoil pad for. Makes a huge difference for lr-308 builds.
