MDT LSS Gen3 Chassis Base, Remington 700 SA

• Modular Gen3 architecture: The MDT LSS Gen3 uses an action-mating chassis base with interchangeable handguard and buttstock interfaces, making it easier to configure the rifle for hunting, competition, tactical use, or general range work without rebuilding the entire platform.
• Zero-preserving component changes: MDT states that handguards and buttstocks can be changed without affecting rifle zero, which is a practical advantage for shooters who want to adapt the rifle to different roles while keeping their established optic setup.
• AICS magazine compatibility: Support for AICS-pattern magazines gives this chassis broad magazine availability and a familiar feeding standard for precision and bolt-action rifle builds.
• AR-style grip compatibility: The chassis accepts AR-15 style grips, allowing the shooter to tailor grip angle and hand position to the rifle’s intended use, whether that means a more vertical precision setup or a field-oriented configuration.
• Lightweight aluminium construction: With an aluminium body and a weight of 998.00 g, the chassis provides a rigid foundation for the Remington 700 short action while keeping overall rifle weight manageable.

About the MDT LSS Series

MDT announced the LSS Gen3 chassis system on February 11, 2025, positioning it as a modular rifle chassis platform for shooters who want one core system that can be adapted to different roles. The MDT LSS concept centers on an action-mating chassis base combined with interchangeable handguards and buttstock interfaces, so the rifle can be configured around the application rather than locked into a single layout.

Within MDT’s lineup, the series is aimed at users who move between competition, hunting, tactical applications, and general shooting. MDT also designed the platform to accept AR-style grips and uses an ambidextrous magazine latch, both of which support a familiar control layout and easier handling across different shooting positions. The availability of Competition, Hunting, and Tactical forends shows the design philosophy clearly: the LSS Gen3 is built as a flexible chassis family that lets the shooter prioritize support-hand placement, accessory mounting, or weight distribution according to the rifle’s job.

About the MDT LSS Gen3 Chassis Base, Remington 700 SA

The MDT LSS Gen3 Chassis Base, Remington 700 SA is built around the Remington 700 short action and gives that action a more configurable foundation than a conventional stock. Its role is not simply to hold the barreled action, but to create a stable starting point for a rifle that may be set up for field use, target work, or a more tactical configuration. Because it belongs to the LSS Gen3 modular system, it is especially well suited to shooters who want to build around one action and then tailor the rifle with different furniture as needs change.

The aluminium construction helps provide the stiffness expected from a chassis system while keeping weight to 998.00 g, which matters when balancing portability against stability. Compatibility with AICS magazines is equally practical, as it supports a widely used magazine pattern for bolt-action rifles and simplifies sourcing magazines for training or match use. The chassis also accepts AR-15 style grips and MDT pistol grips, giving more freedom to tune wrist angle and trigger reach for prone shooting, barricade work, or general hunting carry.

With a maximum barrel diameter of 31.75 mm, the chassis can accommodate substantial barrel profiles, which is useful for precision-oriented builds that benefit from heavier contours. The fixed, non-folding layout keeps the structure straightforward and solid, while the compact 322.00 mm chassis length makes it a clean base for a purpose-built short-action rifle.
