The Magpul CTR Carbine Stock (MAG310-GRY) in Gray is a lightweight, high-performance collapsible stock designed as a drop-in upgrade for AR15, M4, and M16 carbines utilizing a Mil-Spec receiver extension (buffer tube). Engineered for stability, ergonomics, and durability, the CTR provides a secure, rattle-free fit while maintaining a streamlined and snag-resistant profile.

Featuring Magpul’s proven supplemental friction lock system, the CTR minimizes stock movement and wobble for improved shooting consistency and weapon control. The reinforced A-frame profile protects the release latch from accidental activation while enhancing strength without unnecessary bulk.

A comfortable sloping cheek weld and durable rubber butt-pad provide excellent shoulder purchase and consistent sight alignment, even during rapid manipulation or extended range sessions. Integrated ambidextrous QD sling mounts and dual sling loops allow flexible sling configurations for duty, defensive, and competition rifle setups.

The Gray finish offers a modern, neutral aesthetic ideal for two-tone rifle builds and professional configurations while maintaining Magpul’s rugged polymer construction and trusted reliability.

IMPORTANT: This CTR model is designed specifically for Mil-Spec diameter carbine receiver extensions. It will not fit commercial-spec buffer tubes.
