Description
Magpul CTR Stock – Mil-Spec Model (Compact/Type Restricted) is a drop-in replacement buttstock for AR15/M16 carbines using Mil-Spec sized receiver extension tubes.
Designed for light, fast action, its streamlined A-frame profile prevents snagging and shields the release latch to avoid accidental activation.
The CTR Stock also features a supplemental friction lock system that minimizes stock movement for enhanced weapon stability and an ambidextrous QD sling mount compatible with any push-button sling swivel.
The Mil-Spec model includes a 0.3″ thick rubber butt-pad, ensuring a secure shoulder purchase and preventing slippage, even with body armor or modular gear.
