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

The Magpul CTR (Compact/Type Restricted) – Mil-Spec or Commercial Model is a drop-in replacement buttstock for AR15/M16 carbines using mil-spec sized receiver extension tubes. 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 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.
