MDT LSS Gen3 Worker Chassis System, Remington 700 LA

• Modular Gen3 architecture: The LSS Gen3 uses a central chassis body with a separate forend and buttstock interface, making it easier to configure the rifle for hunting, general shooting, or a different support setup without replacing the whole chassis.
• Carbine buttstock interface: This version is built around a carbine-style rear interface, giving the rifle a familiar, adaptable layout and broad compatibility with carbine-pattern stock solutions.
• AICS magazine compatibility: Support for AICS-pattern magazines makes the chassis practical for shooters who want a widely used detachable box magazine standard with strong aftermarket support.
• AR-15 grip compatibility: The chassis accepts AR-15 style grips, allowing the shooter to tailor grip angle and hand fit for better comfort and trigger control.
• Aluminium construction with M-LOK forend: The aluminium chassis provides a rigid foundation for the action, while the M-LOK forend keeps accessory mounting flexible for bipods, rails, and other field equipment.

About the MDT LSS Series

The MDT LSS series is a modular rifle chassis family built around the idea of adapting one core platform to different shooting roles. MDT announced the LSS Gen3 in 2025 as a system that combines an action-mating chassis base with interchangeable handguards and buttstock interfaces, giving shooters a more flexible alternative to a fixed one-piece layout. In the MDT lineup, the LSS sits as a practical crossover design for hunting, tactical use, competition, and general shooting, rather than being limited to one narrow discipline.

A defining characteristic of the series is its ability to accept different forend styles and rear interfaces while keeping the same central chassis. AR-style grip compatibility and an ambidextrous magazine latch reflect a design philosophy focused on familiar controls and straightforward handling. The Gen3 concept also emphasizes easy reconfiguration, with MDT presenting the platform as one where handguards and buttstocks can be changed without disturbing the rifle’s zero. That makes the LSS series especially relevant for shooters who want one chassis system that can be set up for lighter field use, supported range work, or a more utility-focused rifle build.

About the MDT LSS Gen3 Worker Chassis System, Remington 700 LA

The MDT LSS Gen3 Worker Chassis System, Remington 700 LA brings the Gen3 concept to a long-action Remington 700 footprint, making it a strong fit for shooters building a practical hunting rifle or a general-purpose bolt-action around a proven action pattern. Its layout combines a rigid aluminium chassis with a carbine buttstock interface, giving the rifle a modern stock architecture that is easy to tailor to the intended role.

The chassis uses a 305.00 mm M-Lok forend, which keeps the front end streamlined while still allowing direct attachment of accessories such as bipods, rails, and support equipment. For a field rifle, that matters because the shooter can add only what is needed and keep unnecessary bulk to a minimum. The chassis also accepts AR-15 style grips, which helps refine hand position and trigger reach in a way that a traditional stock often cannot. Combined with AICS magazine compatibility, the system supports a widely adopted detachable magazine format that suits both hunting and range use.

With a maximum barrel diameter of 31.75 mm, the chassis leaves room for substantial barrel profiles, while the non-folding design favors simplicity and consistent handling. At 1750.00 g and 685.00 mm in length, it offers a solid, stable base for a long-action rifle without moving into the bulk of a dedicated competition chassis. The result is a chassis system that prioritizes modularity, familiar ergonomics, and practical adaptability for shooters who want a cleaner, more configurable rifle platform.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on rifle chassis systems and the supporting components around them, including magazines, buttstocks, bipods, scope bases, and scope rings. Its first chassis was the TAC21, and that early emphasis on modernizing bolt-action rifle ergonomics still defines the brand today.

MDT is best known for developing products for target shooting and hunting, with design input drawn from competitive precision shooters. That background is especially relevant in a chassis product such as the LSS Gen3, where action fit, magazine function, accessory mounting, and shooter interface all matter as much as raw strength. The company’s product range reflects a practical engineering approach centered on modularity, compatibility, and repeatable rifle setup.
