The Magpul CTR (Compact/Type Restricted) – Mil-Spec model is a drop-in replacement buttstock for AR15 / M16 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 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 0.3" thick rubber butt-pad, which provides positive shoulder purchase to prevent slippage even with body armor or modular gear.
