Designed for light, fast action the streamlined A-frame profile avoids snagging and shields the release latch to prevent accidental activation.

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 should grip to prevent slippage even with body armor or modular gear. Made in the U.S.A.
