The FAB Defense AR-15 GL-Core-M Grip and Gradus Stock Kit in black (brand part no. FXAR15KITB) bundles two of FAB Defense’s ergonomic AR-15 furniture pieces into one kit: the GL-Core-M pistol grip and the Gradus collapsible buttstock. FAB Defense designed the GL-Core-M grip with an internal storage core and a more vertical, ergonomic angle than a standard mil-spec grip, while the Gradus stock adds an adjustable cheek riser and multiple length-of-pull positions on a mil-spec tube. Selling them together as a kit lets builders upgrade both major touchpoints on their AR-15 in one order with matching black finishes.
