Magpul CTR Stock Fits AR-15 Adjustable Black

The Magpul CTR Stock Fits AR-15 Adjustable Black (MAG310-BLK) is a mil-spec drop-in replacement buttstock engineered for AR15/M16 carbines using standard mil-spec receiver extension tubes. The CTR—Compact/Type Restricted—delivers a streamlined profile that eliminates snagging hazards common to bulkier stocks while providing ambidextrous Quick-Detach sling mounting compatibility. This is the buttstock of choice for operators prioritizing compact form factor without sacrificing stability or control.

The A-frame design shields the release latch from accidental activation—a critical feature during high-stress tactical movement or breaching operations. A supplemental friction lock system minimizes excessive stock rattle and movement, reducing unwanted noise and maintaining weapon stability under recoil. The black composite construction resists corrosion and environmental degradation, making it suitable for extended field deployment in varied climates. At 0.75 lbs, the CTR adds minimal mass while maintaining the rigidity needed for consistent cheekweld and shoulder control during precision fire or rapid engagement.

This stock serves law enforcement entry teams, military personnel, competitive shooters, and civilian AR platform builders who demand reliability in confined spaces—vehicle entries, urban environments, or any scenario where a traditional full-length stock creates liability. The adjustable length of pull accommodates body armor, variable plate carriers, and shooting apparel without requiring alternative stocks. Magpul CTR stocks have become standard across tactical units specifically because they balance speed of deployment with ergonomic consistency.

The CTR occupies the middle ground in the AR buttstock market: more compact than full-length A2 or M4 stocks, yet offering more adjustability and features than fixed carbine stocks. Its proven track record across professional end-users and end-consumer builds reflects Magpul's iterative design philosophy—solving real problems discovered in the field rather than pursuing theoretical perfection.
