An Upgrade For MOE Carbine Stocks For Enhanced Weapon Stability
The Magpul CTR Carbine Stock – Commercial-Spec is an upgrade for MOE Carbine stock that features a supplemental friction lock system that minimizes excessive stock movement for enhanced weapon stability.
The Compact/Type Restricted Stock is a drop-in replacement buttstock for AR-15/M16 carbines using Commercial-Spec receiver extensions. Designed for light and fast action capability, the streamlined A-frame profile avoids snagging and shields the release latch to prevent accidental activation.
Supplemental Friction Lock To Minimize Wobbling
Magpul CTR Carbine Stock – Commercial-Spec can be easily installed designed with a low-profile sloping cheek weld for a streamlined look and comfortable aiming. It delivers a solid installation that makes wobbling, rattling, play and noise virtually vanish.
An ambidextrous QD sling mount is added and will accept any push-button sling swivel. This 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.
