The Fab Defense GL-Core M CP Buttstock with Built-In Magazine Carrier brings practical innovation to the AR-15/M4 platform. This survival-focused stock integrates a concealed 10-round AR15/M16/M4 magazine carrier while adding an adjustable cheek piece for a more consistent and comfortable cheek weld. Its reinforced polymer construction and clean, snag-free profile are designed for dependable performance on modern rifle builds.

Beyond the integrated magazine storage, the GL-Core M CP features an anti-rattle mechanism that locks the stock securely on either Mil-Spec or commercial buffer tubes, helping maintain a solid feel during shooting. The rubber butt pad improves shoulder grip and control, making it well suited for range use, training, and general-purpose rifle setups where reliability and readiness matter. Fab Defense’s attention to detail and thoughtful design choices are evident throughout this compact, feature-rich buttstock.
