The Magpul CTR Carbine Stock (MAG310-BLK) is a lightweight, premium collapsible stock designed as a direct upgrade for AR15, M4, and M16 carbines utilizing a Mil-Spec receiver extension (buffer tube). Engineered for stability, durability, and ergonomic performance, the CTR provides a secure, rattle-free fit while maintaining a compact, snag-resistant profile.

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

A comfortable sloping cheek weld and durable 0.30" rubber butt-pad provide excellent shoulder purchase and consistent cheek alignment during rapid fire, training, or duty use. Integrated ambidextrous QD sling mount compatibility and dual sling loops allow flexible sling configurations for defensive, tactical, and competition rifle setups.

The classic Black finish offers a professional, duty-ready appearance that pairs seamlessly with modern AR platforms, making it one of the most trusted stock upgrades for both factory rifles and custom builds.

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