MDT LSS Gen3 Worker Chassis System, Tikka T3x LA

• Modular Gen3 architecture: The MDT LSS Gen3 uses an action-mating chassis base with interchangeable handguards and buttstock interfaces, so the rifle can be configured for hunting, general shooting, or a more specialized role without replacing the whole chassis.
• AR-style grip and carbine stock compatibility: Support for AR-15 style grips and a carbine interface gives shooters broad freedom to tailor grip angle, stock feel, and overall handling to their preferred shooting position.
• M-LOK forend: The M-Lok forend makes it easy to add bipods, sling mounts, and other accessories only where needed, keeping the rifle practical in the field without unnecessary bulk.
• AICS magazine compatibility: Compatibility with AICS-pattern magazines gives this chassis access to a widely used magazine standard, which helps simplify magazine selection for hunting and range use.
• Aluminium construction: The aluminium chassis provides a rigid platform for the action while keeping weight manageable, supporting consistent handling and a more stable shooting setup.

About the MDT LSS Series

MDT announced the LSS Gen3 chassis system on February 11, 2025 as a more adaptable evolution of the company’s compact chassis concept. The series is built around an action-mating chassis base with interchangeable handguards and buttstock interfaces, giving shooters a platform that can be configured for competition, hunting, tactical applications, and general shooting. That modular approach is central to the LSS identity: the chassis can be tailored to the rifle’s role instead of forcing one fixed layout on every build.

A defining feature of the series is its support for AR-style grips, combined with an ambidextrous magazine latch for practical handling from either shoulder. MDT also states that handguards and buttstocks can be changed without affecting rifle zero, which matters for shooters who want to update fit or accessory layout while preserving the rifle’s established setup. Within the Gen3 family, MDT offers Competition, Hunting, and Tactical forends, allowing the same core chassis to serve very different priorities, from lighter field carry to more accessory-focused precision use.

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

The MDT LSS Gen3 Worker Chassis System, Tikka T3x LA is built for shooters who want the handling advantages of a chassis on a Tikka T3x long action without moving to an oversized or highly specialized platform. Its stated applications of general use and hunting make sense for a rifle that needs to balance practical field carry with the more precise feel of a rigid aluminium chassis. The fixed layout keeps the system straightforward, while the carbine buttstock interface opens the door to a wide range of stock options that can change length, balance, and shooting posture to suit the rifle’s intended role.

The M-Lok forend supports a clean, efficient accessory setup. A shooter can mount a bipod, sling hardware, or other essentials without covering the chassis in unused rails, which helps keep the rifle streamlined for field movement. The chassis also accepts AR-15 style grips, an important ergonomic advantage because grip shape and angle have a direct effect on trigger reach and wrist comfort, especially during longer sessions or awkward shooting positions.

Magazine flexibility is another practical strength. With AICS magazine compatibility, the chassis uses a common magazine pattern that is widely favored for bolt-action chassis rifles. The design also accommodates a maximum barrel diameter of 31.75 mm, giving room for heavier barrel profiles often chosen for improved stability. At 1750.00 g and 685.00 mm in length, it remains substantial enough to provide a stable shooting base while still fitting the needs of a hunting-oriented long-action build.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on rifle chassis systems, magazines, buttstocks, and accessories for target shooting and hunting, and its product range also includes bipods, scope bases, and scope rings. MDT identifies the TAC21 as its first chassis, which places chassis design at the center of the company’s development history rather than as a side category.

MDT states that its chassis, magazines, and accessories are developed with input from competitive precision shooters, which helps explain the practical, modular character of its products. The company’s scope bases are CNC-machined from 6061-T6 aluminum and made to MIL-STD-1913 and STANAG 4694 specifications, reflecting a design approach built around compatibility, repeatability, and robust construction. Today, MDT continues to design, manufacture, and sell shooting equipment from its base in British Columbia, Canada.
