The Magpul CTR Carbine Stock Mil-Spec (MAG310-MCB) is one of the most popular and trusted AR-15 and M4 carbine stocks on the market. Finished in Magpul Coyote Brown, this stock combines a compact, tactical profile with Magpul’s signature durability and innovative features. Designed specifically for Mil-Spec buffer tubes, the CTR (Combat TR) Carbine Stock offers a secure, wobble-free fit thanks to its integrated friction lock system, making it a top choice for tactical operators, competitive shooters, and civilian gun owners alike.
Friction Lock System
One of the standout features of the Magpul CTR Carbine Stock is its friction lock mechanism. This system allows the shooter to tighten the stock against the buffer tube, significantly reducing play and movement. The result is a rock-solid platform that maintains consistent cheek weld and point of aim, even during rapid fire or dynamic movement. This feature sets the CTR apart from many standard carbine stocks that can develop looseness over time.
The Magpul CTR Carbine Stock Mil-Spec (MAG310-MCB) delivers a compact, durable, and highly functional upgrade for AR-15 and M4 platforms in Coyote Brown.
Compact and Tactical Design
The CTR Carbine Stock features a slim, streamlined profile that reduces weight and minimizes the chance of snagging on gear or in confined spaces. Despite its compact size, it provides a comfortable and stable shooting position. The stock includes a rubber buttpad that helps absorb recoil and provides a non-slip surface against the shoulder, improving comfort during extended shooting sessions.
Mil-Spec Buffer Tube Compatibility
This model is engineered to fit standard Mil-Spec buffer tubes, ensuring broad compatibility with the majority of AR-15 and M4-style rifles. The secure locking mechanism and friction lock system work together to deliver a tight, reliable fit that won’t shift under recoil or hard use. Whether you’re building a new rifle or upgrading an existing one, the CTR installs quickly and performs consistently.
