Magpul CTR Mil-Spec AR15/M16 Rifle Stock - Flat Dark EarthE - The Magpul CTR (Compact/Type Restricted) Mil-Spec is a drop-in replacement buttstock for AR-15/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 (friction lock performance may vary depending on the host receiver extension's dimensional tolerances) and an ambidextrous QD sling mount that will accept any push-button sling swivel. The Mil-Spec model includes a standard 0.3in thick rubber butt-pad, which provides positive shoulder purchase to prevent slippage even with body armor or modular gear. Made In The USA
