The MDT LSS Gen3 FDE Short LOP XTN Interface is a precision‑engineered buttstock interface designed to integrate seamlessly with the LSS Gen3 chassis system while offering a short‑length‑of‑pull (LOP) configuration for shooters who prefer a more compact, responsive setup. Finished in rugged Flat Dark Earth, this interface provides a robust connection point between the chassis and your choice of buttstock, allowing for ergonomic adjustment and improved handling without sacrificing structural integrity. Built from high‑quality materials and machined to tight tolerances, the XTN interface maintains a solid, repeatable attachment that supports consistent shooting performance. Perfect for shooters who want a lightweight, adaptable platform with a shorter reach back to the trigger, this interface enhances the modular capability of the LSS Gen3 system while allowing easy evolution of stock components over time.
