MDT LSS Gen3 Buttstock Interface, XTN Short

• Modular rear-end conversion: This interface lets an MDT LSS Gen3 chassis accept an XTN buttstock, making it easy to tailor the rifle for hunting, range work, or a different shooting position without changing the core chassis.
• Short XTN format: The XTN Short configuration is intended for compact LSS Gen3 setups, helping maintain a practical length of pull when paired with MDT buttstocks designed around the short interface.
• Aluminium construction: The aluminium body keeps the part light enough for a modular rifle build while still providing the rigidity needed for a secure buttstock mounting point.
• Precision-fit chassis component: As a dedicated LSS Gen3 interface, it is made to fit the chassis base cleanly, so buttstock changes can be done with a factory-style fit rather than improvised adapters.
• Built for evolving rifle setups: This adapter suits shooters who want one chassis to cover several roles, allowing the back end of the rifle to be changed as the application shifts from compact field use to a more adjustable precision-oriented configuration.

About the LSS Gen3 Series

The MDT LSS Gen3 series is built around a modular chassis concept that gives shooters more freedom to configure a rifle around a specific task. Within MDT’s lineup, the LSS Gen3 sits as a flexible platform for users who want a modern chassis system without committing to a single fixed layout. It is aimed at shooters who may move between hunting, general range use, tactical applications, and precision shooting, and who value the ability to reconfigure the rifle as their needs change.

A defining characteristic of the series is its interchangeable architecture. MDT designed the LSS Gen3 around a core chassis base that can accept different handguard and buttstock arrangements, including XTN, carbine, and other interface options. That approach allows the rifle to be adapted for a lighter field setup or a more feature-rich precision build while keeping the same central chassis. The series also follows MDT’s practical design philosophy: straightforward fitment, durable materials, and compatibility with accessories that let shooters refine ergonomics, balance, and support equipment to suit their style.

About the MDT LSS Gen3 Buttstock Interface, XTN Short

The MDT LSS Gen3 Buttstock Interface, XTN Short is a purpose-built adapter for shooters who want to run an XTN-interface buttstock on an MDT LSS Gen3 chassis while keeping the rear of the rifle compact and properly proportioned. Its role is simple but important: it creates the correct mounting point between the chassis base and the chosen buttstock, turning the LSS Gen3 into a more adaptable platform for different shooting disciplines.

The short XTN layout is especially useful when the goal is to avoid unnecessary overall length. That matters on rifles intended for field carry, transport in tighter spaces, or builds where a compact rear profile improves handling. At the same time, using the XTN pattern opens the door to MDT buttstocks that offer a more precision-oriented feel than a basic fixed rear section, making this interface relevant to shooters who want better fit and control from the shoulder.

Its aluminium construction supports that role well. The material keeps weight reasonable at 1000.00 g while still providing the solid connection expected from a structural chassis component. In practice, that means the buttstock interface is not just a spacer or cosmetic part; it is a key element in how the rifle balances, shoulders, and maintains consistency. For anyone building an LSS Gen3 around modularity, this interface is the part that makes an XTN-based stock configuration possible in a clean, factory-matched way.

About MDT

MDT Sporting Goods was established in 2009 and grew out of a focus on practical rifle enhancement for shooters who wanted more capability from factory actions. MDT began in Chilliwack, British Columbia, Canada, and the company continues to operate from British Columbia, Canada. Its product development centers on rifle chassis systems, magazines, buttstocks, and accessories for target shooting and hunting.

A notable part of MDT’s history is the TAC21, which the company identifies as its first chassis. Since then, MDT has expanded into a broad catalog that includes rifle chassis, stocks, magazines, bipods, scope bases, and scope rings. The brand is closely associated with precision rifle shooting, and it states that its chassis, magazines, and accessories are developed with input from competitive precision shooters. That background is directly relevant to parts such as the LSS Gen3 buttstock interface, where fit, modularity, and practical rifle setup matter as much as the material itself.
