The Magpul CTR (Compact/Type Restricted) - Commercial-Spec model is a drop-in replacement buttstock for AR15/M16 carbines using Commercial-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 CTR also features a supplemental friction lock system that minimizes excessive stock movement for enhanced weapon stability and an ambidextrous QD sling mount that will accept any push-button sling swivel. The Commercial-Spec model includes an extended 0.55" thick rubber butt-pad to provide positive shoulder purchase and accommodates the longer, slanted back common to most Commercial-Spec tubes.
Made in the USA.
