The Magpul CTR (Compact/Type Restricted) - Mil-Spec Model is a drop-in replacement butt stock for 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 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.
