MDT LSS Gen3 Tactical Chassis System, Remington 700 LA

• Modular Gen3 architecture: The LSS Gen3 uses a central chassis with interchangeable furniture interfaces, making it easier to configure the rifle for tactical use while keeping the core action fit consistent.
• AR-style grip and carbine interface: Compatibility with AR-15 style grips and a Carbine Interface gives shooters broad freedom to tune grip angle, length of pull, and rear-end setup to suit position shooting or field carry.
• M-LOK tactical forend: The M-Lok forend layout supports lights, bipods, barricade accessories, and other mission-specific add-ons without forcing unnecessary bulk onto the rifle.
• AICS magazine compatibility: Support for AICS magazines makes the chassis practical for precision and tactical rifle builds, with access to a widely used detachable box magazine pattern.
• Aluminium construction: The aluminium chassis keeps the platform rigid and stable, helping the action sit in a solid structure that supports repeatable performance under hard use.

About the MDT LSS Series

The MDT LSS Gen3 series is a modular chassis family introduced in 2025 for shooters who want a compact, configurable foundation for precision, tactical, hunting, and general rifle builds. Rather than treating the chassis as a fixed one-piece format, MDT built the system around an action-mating center chassis that works with interchangeable handguards and buttstock interfaces. That approach gives the LSS Gen3 line a different role in the MDT range: it is aimed at shooters who want one platform that can be adapted to different applications without replacing the entire chassis.

A defining characteristic of the series is its support for AR-style grips, paired with an ambidextrous magazine latch and a choice of forend styles for different priorities. MDT offers Competition, Hunting, and Tactical forend options within the family, allowing the same core chassis concept to be set up for positional shooting, lighter field use, or a more enclosed tactical configuration. Another practical advantage of the LSS Gen3 design is that handguards and buttstocks can be changed without affecting rifle zero, which makes the series especially appealing to shooters who want to reconfigure the rifle around a specific role while keeping the action and optic relationship unchanged.

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

The MDT LSS Gen3 Tactical Chassis System, Remington 700 LA applies the LSS concept to a long-action Remington 700 footprint, giving builders a modern chassis option for precision and tactical rifle projects based on a widely known action pattern. In this version, the emphasis is on a stable aluminium core, a tactical forend layout, and broad compatibility with common accessories and furniture standards. That makes it well suited to shooters who want a rifle that can be configured around supported shooting, barricade work, or general range use rather than a traditional stock format.

The M-Lok tactical forend provides practical mounting space for bipods and other accessories while maintaining a clean, adaptable front end. At the rear, the Carbine Interface opens the door to a broad range of compatible buttstock solutions, while AR-15 style grip compatibility lets the shooter tailor hand position and trigger reach more precisely than with a fixed conventional stock. The chassis is also AICS Magazine Compatible, an important advantage for users building around detachable box magazines that are already common in precision rifle setups.

With a max. barrel diameter of 31.75 mm, the chassis is configured to accept substantial barrel profiles often chosen for stability and heat management in slower, deliberate shooting strings. Its 1950.00 g weight reflects a design that prioritizes rigidity and control over minimum carry weight, while the 851.00 mm overall length and non-folding layout keep the structure straightforward and mechanically simple. The result is a tactical chassis system built around modularity, action support, and familiar accessory standards.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company designs, manufactures, and sells rifle chassis systems, magazines, buttstocks, and accessories for target shooting and hunting, with its head office remaining in British Columbia. MDT is particularly known for building products around the needs of precision rifle shooters, and it states that its chassis, magazines, and accessories are developed with input from competitive shooters.

Within the rifle support and shooting-accessory category, MDT has built its reputation on modular chassis systems and the surrounding ecosystem needed to complete a rifle setup. Its range includes rifle chassis, stocks, magazines, bipods, scope bases, and scope rings, and the company identifies the TAC21 as its first chassis. That background is directly relevant to the LSS Gen3, which reflects MDT's long-standing focus on adaptable rifle platforms for practical field and range use.
