MDT LSS Gen3 Chassis Base, Tikka T3/T3x SA

• Modular Gen3 architecture: The action-mating chassis base is built around the MDT LSS Gen3 system, allowing compatible forends and buttstock interfaces to be changed as needs evolve while keeping the rifle in the same chassis family.
• AICS magazine compatibility: Support for AICS-pattern magazines gives this chassis broad magazine availability and makes it easier to configure a Tikka short-action rifle for hunting, general shooting, competition, or tactical use.
• AR-style grip interface: Compatibility with AR-15 style grips and MDT pistol grips lets the rifle be tailored to preferred hand angle and trigger reach, improving comfort during longer shooting sessions.
• Rigid aluminum construction: The aluminium chassis keeps weight to 998.00 g while providing the stiffness expected from a modern bolt-action chassis, helping the rifle feel stable without becoming unnecessarily heavy.
• Barrel clearance for modern builds: With support for a 31.75 mm maximum barrel diameter, the chassis base accommodates heavier barrel profiles often chosen for precision-oriented or multi-role rifle setups.

About the MDT LSS Series

MDT announced the LSS Gen3 chassis system on February 11, 2025, positioning it as a more flexible evolution of the LSS concept for shooters who want one chassis platform to cover different roles. The MDT LSS family is aimed at users who need a compact, modular bolt-action chassis for competition, hunting, tactical applications, and general shooting, rather than a fixed one-purpose stock.

A defining trait of the series is its action-mating chassis base combined with interchangeable handguards and buttstock interfaces. That layout gives the system room to adapt as a rifle changes from a lighter field setup to a more support-oriented range configuration. MDT also states that handguards and buttstocks can be changed without affecting rifle zero, which is a practical advantage for shooters who want to reconfigure the rifle without starting over on setup. The series is also designed to accept AR-style grips and uses an ambidextrous magazine latch, reinforcing its focus on familiar controls, modular ergonomics, and broad compatibility within the MDT ecosystem.

About the MDT LSS Gen3 Chassis Base, Tikka T3/T3x SA

The MDT LSS Gen3 Chassis Base, Tikka T3/T3x SA is built for shooters using a Tikka T3/T3x short action who want to move from a conventional stock to a more configurable chassis platform. Its role is not simply to hold the action, but to provide a rigid foundation for a rifle that may be used across competition, hunting, tactical, and general applications. That makes it suitable for shooters who want one rifle to cover several jobs without committing to a fixed stock layout.

The chassis uses an aluminium construction and weighs 998.00 g, balancing structural rigidity with manageable overall mass. At 322.00 mm in length, it forms a compact base that can be built out according to the intended use of the rifle. Compatibility with AICS magazines is especially important in practice, because it opens the door to a widely used magazine pattern for short-action cartridges and simplifies sourcing spares or setting up the rifle for different capacities.

Ergonomically, the chassis supports AR-15 style grips as well as MDT pistol grips, which allows the shooter to tune grip angle and hand position to the task. That matters when moving between field shooting, positional stages, and bench work, where comfort and trigger access can influence consistency. The 31.75 mm maximum barrel diameter also gives the chassis room for heavier barrel contours often chosen for precision shooting, while the non-folding layout keeps the structure straightforward and solid for users who prioritize simplicity over transport compactness.

About MDT

MDT states that its chassis, magazines, and accessories are developed with input from competitive precision shooters, which helps explain the brand’s emphasis on modularity, practical ergonomics, and compatibility across different rifle setups.
