MDT LSS Gen3 Worker Chassis System, Tikka T3x SA

• Modular LSS Gen3 platform: The action-mating chassis base works with interchangeable handguards and buttstock interfaces, making it easier to configure the rifle for hunting, general shooting, or a more tactical setup without replacing the entire chassis.
• AR-style grip and carbine stock compatibility: Support for AR-15 style grips and a Carbine Interface gives the rifle a familiar control layout and broad aftermarket fitment, helping shooters tailor grip angle, length of pull, and overall handling.
• AICS magazine compatibility: Compatibility with AICS-pattern magazines gives access to a widely used detachable magazine format, which simplifies reloads and makes it easier to match the rifle to common precision and hunting magazine options.
• Rigid aluminium construction: The aluminium chassis adds a stable bedding platform that supports repeatable action fit and consistent rifle behavior, especially useful when accuracy and durability matter more than a traditional stock feel.
• M-LOK forend interface: The M-LOK forend layout allows direct mounting of accessories such as bipods, rails, and support gear, so the rifle can be set up cleanly without unnecessary bulk.

About the MDT LSS Series

The MDT LSS series is built around a compact, modular chassis concept that gives bolt-action rifles a more adaptable layout than a conventional stock. MDT announced the LSS Gen3 chassis system on February 11, 2025, positioning it as a flexible platform for competition, hunting, tactical applications, and general shooting. Rather than treating the chassis as a fixed one-piece solution, the Gen3 system uses an action-mating chassis base with interchangeable handguards and buttstock interfaces.

That design approach matters in practice because it lets the rifle evolve with the shooter’s needs. MDT states that handguards and buttstocks can be changed without affecting rifle zero, which is valuable for anyone moving between field use, range work, and more specialized setups. The series also accepts AR-style grips and uses an ambidextrous magazine latch, combining familiar ergonomics with easier operation from either shoulder. Within the Gen3 family, MDT introduced Competition, Hunting, and Tactical forends, so the LSS line is aimed at shooters who want a chassis that can be configured around a specific role without giving up the core advantages of a rigid, magazine-fed precision platform.

About the MDT LSS Gen3 Worker Chassis System, Tikka T3x SA

The MDT LSS Gen3 Worker Chassis System, Tikka T3x SA is a fixed chassis for shooters who want the handling and modularity of a modern rifle chassis on a Tikka T3x short action. Its layout is suited to general shooting and hunting, where a stable action interface, detachable magazine use, and practical accessory mounting are more important than the traditional shape of a factory stock. The chassis is built from aluminium, which helps provide the rigidity expected from a precision-oriented platform while standing up well to regular field use.

The M-LOK forend gives the rifle a straightforward way to accept bipods, rails, and other support accessories, keeping the setup adaptable without adding unnecessary mounting hardware. With a 305.00 mm forend length and support for a maximum barrel diameter of 31.75 mm, the chassis is configured for practical barrel clearance while maintaining a compact overall footprint. The Carbine Interface opens the door to a wide range of compatible buttstock solutions, while AR-15 style grip compatibility lets the shooter tune grip shape and angle to personal preference.

Functionally, AICS magazine compatibility is one of the key advantages of this chassis system. It allows the rifle to use a widely adopted detachable box magazine pattern, which is useful for faster reloads and easier integration into existing precision-rifle setups. At 1750.00 g and 685.00 mm in length, this is a substantial but still field-usable chassis that prioritizes control, repeatability, and configuration flexibility over minimum weight.

About MDT
