MDT LSS Gen3 Worker Chassis System, Remington 700 SA

• Modular LSS Gen3 architecture: The chassis uses an action-mating base with interchangeable handguard and buttstock interfaces, giving the rifle a flexible foundation that can be adapted for hunting, general shooting, or a more specialized setup without replacing the core chassis.
• AR-pattern grip and carbine interface: Compatibility with AR-15 style grips and a carbine interface makes it easier to tailor grip angle, stock feel, and overall handling to the shooter’s preferred position and use case.
• AICS magazine compatibility: Support for AICS-pattern magazines gives access to a widely used detachable box magazine format, helping simplify reloads and magazine sourcing for practical field or range use.
• M-Lok forend layout: The M-Lok forend provides straightforward mounting for bipods, sling attachments, and other accessories while keeping the front end clean and adaptable to different shooting roles.
• Aluminium construction: The aluminium chassis body provides a rigid bedding platform with the durability needed for regular field and range use, helping the rifle maintain consistent handling and support under hard use.

About the MDT LSS Series

The MDT LSS series is built around a compact, modular chassis concept that gives bolt-action rifles a more adaptable layout than a conventional stock. MDT announced the LSS Gen3 chassis system on February 11, 2025, positioning it as a flexible platform for competition, hunting, tactical applications, and general shooting. Rather than treating the chassis as a fixed one-piece format, the system uses an action-mating chassis base with interchangeable handguards and buttstock interfaces, allowing the rifle to be configured around the shooter’s intended role.

A defining trait of the series is its compatibility with AR-style grips, combined with an ambidextrous magazine latch that supports practical handling from either side. MDT also introduced Competition, Hunting, and Tactical forends for the Gen3 platform, showing that the LSS line is meant to cover everything from lighter field rifles to more support-oriented range builds. MDT states that handguards and buttstocks can be changed without affecting rifle zero, which is especially useful for shooters who want to alter ergonomics or accessory space while keeping the rifle’s established setup intact. In practice, the LSS series suits users who want a chassis system that stays mechanically straightforward while leaving room for meaningful configuration changes over time.

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

The MDT LSS Gen3 Worker Chassis System, Remington 700 SA is a fixed chassis built for shooters who want the modular logic of the LSS Gen3 platform in a practical configuration for a Remington 700 short action. Its role is straightforward: provide a rigid aluminium chassis foundation that supports hunting and general-purpose rifle builds while preserving the ability to tailor the rifle’s contact points and front-end accessories to the task at hand.

The chassis combines an M-Lok forend with a carbine buttstock interface, which makes it easier to set up the rifle around preferred accessories and stock geometry. The M-Lok layout gives useful mounting space for items such as a bipod or sling hardware without forcing unnecessary bulk into the front end, while the carbine interface opens the door to a familiar rear-end format for shooters who prefer that style of adjustment and handling. AR-15 style grip compatibility adds another important ergonomic advantage, since grip shape and angle can have a noticeable effect on wrist comfort and trigger control during longer sessions.

Functionally, AICS magazine compatibility keeps the rifle aligned with a widely used detachable magazine standard, which is valuable for both convenience and practical field use. The chassis also accommodates a maximum barrel diameter of 31.75 mm, giving room for heavier barrel profiles often chosen for stability and heat management. At 1750.00 g and 685.00 mm in length, it remains a substantial but manageable fixed chassis option for shooters building a modern bolt-action rifle around dependable magazine function, accessory mounting flexibility, and familiar aftermarket grip and stock interfaces.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on designing, manufacturing, and selling rifle chassis systems, magazines, buttstocks, and accessories for target shooting and hunting. MDT identifies the TAC21 as its first chassis, which helps place the company’s background firmly in modern rifle support systems rather than in general outdoor equipment.

Today, MDT’s head office remains in British Columbia, Canada, and its catalogue covers chassis, stocks, magazines, bipods, scope bases, and scope rings. The brand is especially associated with modular rifle platforms developed with input from competitive precision shooters, which is relevant to products such as the LSS Gen3. That emphasis on practical rifle setup, accessory compatibility, and shooter-driven ergonomics has made MDT a recognized name among users building bolt-action rifles for precision shooting, hunting, and crossover field applications.
