MDT LSS Gen3 Tactical Chassis System, Tikka T3x SA

• Modular LSS Gen3 platform: The action-mating chassis base uses the MDT LSS Gen3 system architecture, allowing the rifle to be configured around different furniture and application needs while keeping the core chassis interface consistent.
• Tactical fixed chassis layout: With a non-folding design and Carbine Interface buttstock mounting, this chassis gives the rifle a stable, straightforward setup suited to tactical shooting and range use.
• AICS magazine compatibility: Support for AICS-pattern magazines makes it easier to build around a widely used detachable box magazine standard for practical loading and reload management.
• AR-pattern ergonomics: Compatibility with AR-15 style grips lets shooters tailor grip angle and hand fit to their preferred shooting position, which can improve comfort and trigger control.
• M-LOK forend utility: The M-LOK forend provides a practical mounting surface for bipods, barricade accessories, and other support equipment without adding unnecessary bulk.

About the MDT LSS Series

MDT announced the LSS Gen3 chassis system on February 11, 2025 as a more flexible evolution of the company’s compact chassis concept. Within MDT’s lineup, the LSS Gen3 sits as a modular platform for shooters who want a lighter, more configurable alternative to a traditional stock while still keeping the rifle adaptable for competition, hunting, tactical applications, and general shooting. A key part of the series is its action-mating chassis base, which works with interchangeable handguards and buttstock interfaces so the rifle can be set up around different priorities.

The series is defined by that modular design philosophy. MDT offers Competition, Hunting, and Tactical forends for the LSS Gen3, giving the same core chassis a different feel and accessory layout depending on the role. MDT also states that handguards and buttstocks can be changed without affecting rifle zero, which is especially useful for shooters who want to reconfigure the rifle without starting over on setup. The platform is designed to accept AR-style grips and includes an ambidextrous magazine latch, reinforcing its focus on familiar controls, practical customization, and broad usability across modern bolt-action builds.

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

The MDT LSS Gen3 Tactical Chassis System, Tikka T3x SA is built for shooters who want to move a short-action Tikka rifle into a more modular, support-ready chassis format. Its tactical application focus is reflected in the fixed layout, the M-LOK forend, and the Carbine Interface at the rear, which together create a platform that is easy to configure around positional shooting, bipod use, and range work. For a rifle that may be used from barricades, bags, or improvised supports, that kind of layout matters because it gives the shooter more options for mounting accessories and refining fit.

The chassis is made from aluminium, with a listed weight of 1950.00 g and an overall length of 851.00 mm. That construction gives the rifle a more rigid foundation than a conventional stock, which can help maintain a consistent feel under recoil and during repeated shooting strings. The AICS Magazine Compatible design supports a widely used detachable magazine pattern, making the system practical for shooters who already run AICS-format magazines on other rifles. Compatibility with AR-15 Style Grips adds another useful layer of personalization, allowing the grip shape and angle to be chosen around the shooter’s hand size and preferred firing position.

The chassis also accommodates a maximum barrel diameter of 31.75 mm, which is relevant for heavier-profile barrel setups often chosen for precision and tactical builds. With a 348.00 mm forend length and a non-folding structure, this model emphasizes stability, straightforward handling, and a clean accessory interface rather than compact transport features.

About MDT

MDT Sporting Goods was established in 2009 and is based in British Columbia, Canada, with roots in Chilliwack. The company focuses on equipment for modern rifle setups, designing and manufacturing rifle chassis systems, magazines, buttstocks, and accessories for target shooting and hunting. Its wider catalog also includes bipods, scope bases, and scope rings, reflecting a specialization in the supporting hardware around precision rifles rather than general outdoor gear.

MDT identifies the TAC21 as its first chassis, and that early focus on chassis design still defines the brand. The company states that its chassis, magazines, and accessories are developed with input from competitive precision shooters, which helps explain the practical, modular approach seen across its product range. For shooters building a bolt-action rifle around modern ergonomics and accessory compatibility, MDT is best known for turning traditional actions into more adaptable precision platforms.
