MDT LSS Gen3 Tactical Chassis System, Remington 700 SA

• Modular Gen3 architecture: The LSS Gen3 uses an action-mating chassis base with interchangeable handguards and buttstock interfaces, making it easier to configure the rifle for tactical use while keeping the setup adaptable as needs change.
• AR-style grip compatibility: Support for AR-15 style grips lets shooters tailor grip angle and hand position, which helps build a more natural firing position for prone, bench, or positional shooting.
• AICS magazine compatibility: The chassis accepts AICS-pattern magazines, giving access to a widely used detachable box magazine format that supports faster reloads and broad magazine availability.
• M-LOK tactical forend: Its M-LOK forend provides practical mounting space for bipods, barricade accessories, lights, or other mission-specific equipment without adding unnecessary bulk.
• Aluminium chassis construction: The aluminium body provides a rigid platform for the Remington 700 short action, helping maintain consistent action support while standing up to hard field and range use.

About the MDT LSS Series

The MDT LSS series is built around a modular chassis concept that gives bolt-action rifles a more adaptable layout for tactical, hunting, and general shooting roles. With the LSS Gen3 generation introduced in 2025, MDT expanded the system with a chassis base that works with interchangeable handguards and buttstock interfaces, allowing the rifle to be configured around different applications rather than locking the user into a single format.

A defining characteristic of the series is its practical compatibility with AR-style grips and its use of an ambidextrous magazine latch, features that bring familiar handling and efficient magazine changes to a precision bolt-action platform. MDT also developed the Gen3 family around multiple forend styles, including Competition, Hunting, and Tactical variants, so the same core chassis system can be tailored for different priorities such as accessory mounting, weight distribution, or field handling. Another important part of the LSS concept is that handguards and buttstocks can be changed without affecting rifle zero, which makes the platform especially useful for shooters who want to refine rifle fit or mission setup over time.

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

The MDT LSS Gen3 Tactical Chassis System, Remington 700 SA is designed for shooters who want to turn a Remington 700 short action into a more configurable precision or tactical rifle platform. Its fixed chassis layout emphasizes rigidity and repeatable action support, while the Gen3 architecture adds flexibility through interchangeable components. In practical terms, that means the rifle can be set up around a specific role today and still remain adaptable as accessories, support gear, or shooting style evolve.

The M-LOK tactical forend is central to that role. With a 348.00 mm forend length, it provides useful space for mounting a bipod, tripod interface, barricade stop, or other accessories often used in supported and positional shooting. The chassis also accepts AR-15 style grips, which is important for shooters who want to fine-tune grip angle and hand placement for better trigger control. Combined with the Carbine Interface buttstock attachment, the system leaves room to build a rifle around preferred stock geometry and rear support characteristics.

Magazine handling is equally practical. Because the chassis is AICS Magazine Compatible, it works with one of the most common detachable box magazine patterns used in precision rifle shooting. The 31.75 mm maximum barrel diameter also supports heavier barrel profiles often chosen for stability and heat management. With its aluminium construction, 1950.00 g weight, and 851.00 mm overall length, this MDT chassis balances structural strength, accessory support, and the modularity expected from a modern tactical bolt-action chassis.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on equipment for precision-oriented rifle shooting, designing and manufacturing rifle chassis systems, magazines, buttstocks, and related accessories for target shooting and hunting. Its product range also includes bipods, scope bases, and scope rings, reflecting a broad specialization in rifle support hardware rather than general outdoor gear.

A notable part of MDT’s history is the TAC21, which the company identifies as its first chassis. MDT also states that its chassis, magazines, and accessories are developed with input from competitive precision shooters, which helps explain the strong emphasis on modularity, compatibility, and practical rifle ergonomics across the lineup. For chassis products such as the LSS Gen3, that background is especially relevant: MDT’s design approach centers on giving bolt-action rifles a more stable, configurable interface for modern precision and tactical applications.
