Matador Arms MAG-X
The Matador Arms MAG-X is a magazine adapter that lets you convert any mil-spec AR-15 lower receiver to accept your favorite pistol magazines. Whether you run Glock® 17/19, Sig Sauer® P320™, or CZ® 75 mags, the MAG-X allows for quick and seamless conversion—no permanent modifications or special tools required. It’s the ideal solution for pistol-caliber carbine (PCC) enthusiasts looking to unify their AR and sidearm platforms with shared magazines.
Engineered for precision and ease of use, the Matador Arms MAG-X installs in seconds and locks into your AR-15 lower using the standard magazine catch. The unit is machined from lightweight aircraft-grade aluminum and finished with a durable anodized coating. For added strength and reliability, the integrated magazine catch and ejector are constructed from steel. The adapter also features a built-in magazine release, allowing for fast reloads while maintaining familiar AR-15 controls.
This adapter is designed to function with any standard AR-15 mil-spec lower in combination with a 9mm upper that utilizes a Glock-cut bolt. While the MAG-X is designed for easy drop-in installation, hand-fitting may be required for some FM-9 upper receivers. It is not compatible with CMMG radial delayed blowback systems and does not provide last-round bolt hold open.
The Matador Arms MAG-X is ideal for use with the Matador Arms MAT-9 Complete Upper Receiver, creating a seamless and efficient 9mm AR build. This pairing provides shooters with a robust, streamlined PCC that can accept commonly available pistol magazines while retaining the handling and modularity of the AR platform.
