MDT LSS Gen3 Chassis Base, Tikka T1x

• Modular LSS Gen3 architecture: The chassis base is built around MDT’s Gen3 system, letting the rifle be configured with different buttstock interfaces and forend styles to suit hunting, competition, tactical or general shooting roles without changing the core action fit.
• Lightweight aluminium construction: At 998.00 g, the chassis keeps overall rifle weight under control while adding the rigidity needed for more consistent support than a conventional factory stock.
• AICS magazine compatibility: Support for AICS-pattern magazines makes magazine selection straightforward and gives the rifle access to a widely used detachable box magazine standard.
• AR-style grip compatibility: The chassis accepts AR-15 style grips and MDT pistol grips, making it easier to tailor grip angle and hand position to the shooter’s preferred setup.
• Barrel clearance for upgrades: With support for barrels up to 31.75 mm in diameter, the chassis leaves room for heavier-profile rimfire builds intended for precision practice or match use.

About the MDT LSS Series

The MDT LSS Gen3 series is a modular chassis family introduced in 2025 for shooters who want one rifle platform to cover more than one role. In MDT’s lineup, the LSS Gen3 sits as a flexible system that combines a compact action-specific chassis base with interchangeable furniture, rather than locking the rifle into one fixed stock format. That makes it relevant for competition, hunting, tactical applications, and general shooting, especially for owners who want to adapt the same rifle over time.

A defining characteristic of the series is its action-mating chassis base paired with changeable handguards and buttstock interfaces. MDT designed the system so these external components can be swapped without affecting zero, which is a practical advantage for shooters who move between field and range setups. The series also uses AR-style grip compatibility and an ambidextrous magazine latch, giving it familiar ergonomics and easier handling from either shoulder. Within the LSS Gen3 family, MDT offers dedicated Competition, Hunting, and Tactical forends, so the system can be configured around balance, accessory mounting, or carry comfort depending on the rifle’s intended use.

About the MDT LSS Gen3 Chassis Base, Tikka T1x

The MDT LSS Gen3 Chassis Base, Tikka T1x gives the popular rimfire action a more rigid and configurable foundation for training, small-game use, and precision rimfire competition. Its main advantage is not simply that it replaces the factory stock, but that it moves the rifle into a true chassis format with broader compatibility for grips, magazines, and future furniture changes. For shooters using the Tikka T1x as a trainer for centerfire precision rifles, that matters because the rifle can be set up with controls and ergonomics that feel closer to a larger match or tactical platform.

The chassis is made from aluminium, which helps provide the stiffness needed for stable action support while keeping weight to 998.00 g. That balance suits a rimfire rifle well: substantial enough to support positional shooting and barrel upgrades, but still manageable for field carry. Compatibility with AICS magazines broadens magazine options, while support for AR-15 style grips and MDT pistol grips allows the shooter to tune wrist angle and hand placement for prone, bench, or improvised positions. The chassis also accommodates a maximum barrel diameter of 31.75 mm, which is useful for heavier-barrel T1x builds aimed at accuracy work. With its fixed base layout and non-folding design, this model focuses on simplicity, rigidity, and a clean starting point for a purpose-built rimfire chassis rifle.
