The MDT LSS Gen3 FDE Pistol Interface Assembly is a precision‑engineered buttstock interface designed specifically for the MDT LSS Gen3 chassis system, giving shooters a modular way to attach and swap buttstocks on their rifle build. This interface unit provides a rock‑solid connection between the chassis and a variety of compatible buttstock options — whether you’re mounting a fixed stock or a carbine‑style unit — so you can adjust ergonomics, balance, and overall handling to suit competition, hunting, or tactical applications. Constructed from high‑strength materials and finished in a durable Flat Dark Earth color, it ensures dependable performance in rugged use and lets you evolve your rifle configuration without compromising stability or fit. When paired with the rest of the LSS Gen3 chassis system, this interface offers flexibility and adaptability as your shooting needs change over time.
