The Fab Defense GL-CORE AR15/M4 Buttstock for Mil-Spec and Commercial Tubes OD Green delivers a solid, repeatable shoulder interface in a compact skeletonized profile. Its integrated cheek weld and ergonomic rubberized buttpad work together to keep the rifle stable while promoting fast, natural shouldering on both training and duty-style carbines.

This GL-CORE configuration is tailored for AR-15 and M4 platforms using either Mil-Spec or commercial buffer tubes, making it a versatile upgrade for a wide range of rifles. The interchangeable tube adapters help eliminate wobble, while the sleek OD Green housing minimizes snag points for smooth handling during range sessions, classes, or general-purpose use. Fab Defense’s attention to detail and durable fiberglass-reinforced polymer construction reflect the brand’s reputation for thoughtful, shooter-focused design.
