The patent-pending Magpul CTR (Compact/Type Restricted) – Mil-Spec Model is a drop-in replacement butt stock for carbines using mil-spec 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.
Note: There are two basic types of M4 Carbine receiver extensions (buffer tubes): mil-spec and commercial-spec. If you have a commercial-spec extension on your rifle, make sure to order the Commercial-Spec CTR:
CTR Carbine Stock – Commercial-Spec. If you have one of the uncommon military tubes with an extended slant-back, please contact Magpul for the extended 0.55" rubber butt-pad (sold separately).
Made in U.S.A.
* Friction lock performance may vary depending on the receiver extension's dimensional tolerances.
