The Fab Defense GL-Core Impact Rifle Stock Black is a recoil-absorbing buttstock engineered to tame sharp recoil while maintaining a compact, modern profile. Built around an internal spring system with three selectable recoil settings, it lets you tune how much impact is soaked up at the shoulder, whether you are running light 5.56 loads or heavier buckshot. The rigid composite body and rubberized buttpad work together to provide a stable, repeatable cheek weld and consistent control shot after shot.

This model is designed for AR-15 and other carbines that use Mil-Spec or commercial carbine receiver extensions, making it a straightforward upgrade for many modern rifles. Its ambidextrous-friendly layout, ergonomic geometry, and easy length-of-pull adjustment make it well suited for range practice, training, and general-purpose rifle use where comfort and control matter over long sessions. The GL-Core Impact reflects Fab Defense’s focus on practical innovation and durable, shooter-focused design.
