MDT LSS Gen3 Chassis Base, Remington 700 LA

• Modular Gen3 architecture: The LSS Gen3 uses a central chassis base with interchangeable buttstock interfaces and forends, letting the rifle be configured for hunting, tactical use, competition, or general range work without replacing the core chassis.
• Zero-retaining component changes: The LSS Gen3 system is designed so handguards and buttstocks can be changed without affecting rifle zero, which makes it practical to adapt the rifle to different roles while keeping the optic setup consistent.
• Lightweight aluminium construction: At 998.00 g, the chassis keeps weight under control while providing the rigidity expected from a metal bedding platform, helping balance portability with stable action support.
• AICS magazine compatibility: Support for AICS-pattern magazines gives broad magazine choice and makes the chassis easier to integrate into established precision and field rifle setups.
• AR-style grip compatibility: Compatibility with AR-15 style grips and MDT pistol grips allows the rifle to be tailored to preferred hand angle and trigger reach, improving comfort over long shooting sessions.

About the MDT LSS Series

The MDT LSS series is built around a modular chassis concept that gives shooters a compact central base and the freedom to configure the rifle around the job at hand. In its Gen3 form, the system uses an action-mating chassis base with interchangeable handguards and buttstock interfaces, creating a platform that can move between competition, hunting, tactical applications, and general shooting with fewer compromises than a fixed-format stock.

A defining characteristic of the series is that handguards and buttstocks can be changed without affecting rifle zero. In practical use, that means a rifle can be adapted for a lighter field setup or a more support-oriented range configuration while preserving the established optic setup. The series is also designed to accept AR-style grips, giving shooters access to familiar ergonomics, and it incorporates an ambidextrous magazine latch for easier handling from either side. Within MDT’s lineup, the LSS Gen3 stands out as a flexible chassis family for shooters who want one rifle system that can be reconfigured rather than replaced.

About the MDT LSS Gen3 Chassis Base, Remington 700 LA

The MDT LSS Gen3 Chassis Base, Remington 700 LA is the core of a configurable rifle build for the Remington 700 long action. Rather than locking the shooter into a single stock and forend layout, this chassis base forms the central structure of the rifle and allows the rest of the system to be tailored around the intended role. That makes it well suited to shooters who want one long-action rifle that can serve in hunting, tactical, competition, or general shooting depending on how it is equipped.

The chassis is made from aluminium, which gives it the stiffness expected from a modern chassis while keeping overall weight to 998.00 g. That balance matters in practice: the rifle gains a more stable and repeatable action interface than a conventional stock, but without adding unnecessary bulk to a field rifle. The 322.00 mm chassis length and 31.75 mm maximum barrel diameter support a purposeful, compact center section that leaves the final handling characteristics to the chosen forend and buttstock combination.

Compatibility is one of this model’s strongest points. It accepts AICS magazines, making it easier to use proven detachable box magazine patterns, and it works with AR-15 style grips as well as MDT pistol grips, so grip angle and hand fit can be tuned to the shooter. Because the LSS Gen3 system is built around interchangeable components, this chassis base is especially useful for shooters who want to refine rifle balance, support-hand position, and overall handling without changing the action interface itself.
