MDT LSS Gen3 Chassis Base, Savage Axis SA

• Modular chassis architecture: The MDT LSS Gen3 uses an action-mating chassis base with interchangeable buttstock interfaces and forends, so the rifle can be configured for hunting, tactical use, competition, or general range work without replacing the core chassis.
• AR-style grip compatibility: Support for AR-15 style grips and MDT pistol grips makes it easier to tailor grip angle and hand position to the shooter, improving comfort and trigger control across different shooting positions.
• AICS magazine compatibility: The chassis accepts AICS-pattern magazines, giving the Savage Axis short action a widely used detachable box magazine standard that is practical for both field use and structured shooting disciplines.
• Rigid aluminium construction: Its aluminium body provides a stable bedding platform while keeping weight to 998.00 g, helping the rifle stay manageable without giving up the consistency expected from a chassis system.
• Barrel clearance for modern builds: With support for up to 31.75 mm barrel diameter, the chassis suits heavier barrel profiles often chosen for precision and crossover rifles, allowing more flexibility when building around accuracy-focused components.

About the MDT LSS Series

MDT announced the LSS Gen3 chassis system on February 11, 2025, positioning it as a flexible platform for shooters who want a lighter, more adaptable rifle chassis than a conventional one-piece stock. The MDT LSS family is built around an action-mating chassis base that works with interchangeable handguards and buttstock interfaces, giving the system a modular structure rather than a fixed layout. That matters for shooters who move between hunting, tactical training, general range use, and competition, because the rifle can be reconfigured around the same core fitment.

A defining trait of the series is its support for AR-style grips and its ambidextrous magazine latch, both of which reflect MDT’s focus on practical handling. MDT also introduced dedicated Competition, Hunting, and Tactical forends for the Gen3 generation, allowing the same chassis family to be tuned toward steadier barricade work, lighter field carry, or broader all-round use. Another important part of the design is that handguards and buttstocks can be changed without affecting rifle zero, which makes the LSS Gen3 especially useful for shooters who want one rifle system to cover multiple roles without starting from scratch each time.

About the MDT LSS Gen3 Chassis Base, Savage Axis SA

The MDT LSS Gen3 Chassis Base, Savage Axis SA is built for shooters who want to move a Savage Axis short action into a more rigid, magazine-fed chassis format while keeping the rifle adaptable to different roles. Its core advantage is not just that it replaces a factory stock, but that it creates a more structured foundation for the action, helping the rifle feel more stable in positional shooting, field use, and supported precision work. Because it is part of the LSS Gen3 system, it also serves as the starting point for a modular build rather than a fixed-end configuration.

The chassis is made from aluminium and weighs 998.00 g, which keeps the base light enough for practical hunting and general-purpose rifles while still giving the solid feel expected from a chassis platform. Compatibility with AICS magazines is especially important in use, because it opens the rifle to a common detachable magazine standard that is widely preferred for reload speed, availability, and cross-platform familiarity. The ability to use AR-15 style grips or MDT pistol grips further improves ergonomics, letting the shooter choose a grip shape and angle that better suits prone shooting, bench work, or more upright field positions.

With support for barrel diameters up to 31.75 mm, this chassis base also accommodates heavier-profile builds that benefit from added stiffness and heat capacity. Its application range of Competition, General, Hunting, Tactical reflects how the design is meant to bridge disciplines: light enough to carry, structured enough for precision-oriented shooting, and modular enough to evolve with the rifle over time.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on rifle chassis systems, magazines, buttstocks, and related accessories for target shooting and hunting, and it has built its reputation around products that bring modularity and precision-oriented ergonomics to bolt-action rifles. MDT states that its chassis, magazines, and accessories are developed with input from competitive precision shooters, which helps explain the practical, shooter-driven layout seen across its product range.

Today, MDT designs, manufactures, and sells rifle chassis systems alongside stocks, bipods, scope bases, scope rings, and magazines. The company identifies the TAC21 as its first chassis, and that early emphasis on chassis design remains central to the brand. In this category, MDT is particularly known for building systems that let shooters adapt rifle fit, accessory mounting, and magazine format to specific shooting disciplines without abandoning the original action.
