MDT LSS Gen3 Chassis Base, Ruger 10/22

• Gen3 modular chassis architecture: The LSS Gen3 uses an action-mating chassis base with interchangeable forend and buttstock interfaces, making it easier to configure the rifle for hunting, competition, tactical use, or general range work without rebuilding the entire platform.
• AR-style grip compatibility: Support for AR-15 pattern grips lets the rifle be tailored to hand size and shooting style, improving trigger reach and overall control in field and positional shooting.
• Ruger 10/22 magazine compatibility: Native compatibility with Ruger 10/22 magazines keeps magazine sourcing simple and preserves the familiar handling of one of the most common rimfire platforms.
• Aluminium chassis construction: The aluminium body gives the rifle a rigid bedding platform that helps maintain consistent action support while keeping weight to a manageable 998.00 g.
• 31.75 mm barrel clearance: The chassis accepts barrels up to 31.75 mm in diameter, giving builders room for heavier profiles suited to precision rimfire setups and sustained range sessions.

About the MDT LSS Series

MDT announced the LSS Gen3 chassis system on February 11, 2025 as a more adaptable evolution of the LSS concept. In MDT’s lineup, the series sits as a modular chassis platform for shooters who want to start with a compact action-mating base and then choose the furniture that best matches the rifle’s role. That makes it relevant across competition, hunting, tactical applications, and general shooting, rather than being tied to a single discipline.

A defining characteristic of the series is its use of interchangeable handguards and buttstock interfaces. MDT designed the system so that handguards and buttstocks can be changed without affecting rifle zero, which is especially useful for shooters who want one rifle to serve in different configurations. The LSS Gen3 also accepts AR-style grips and uses an ambidextrous magazine latch, reflecting a design approach focused on familiar controls, flexible ergonomics, and practical field adaptability. MDT also announced Competition, Hunting, and Tactical forends for the platform, reinforcing the series’ role as a configurable chassis family rather than a fixed one-piece stock.

About the MDT LSS Gen3 Chassis Base, Ruger 10/22

The MDT LSS Gen3 Chassis Base, Ruger 10/22 brings the LSS Gen3 concept to one of the most widely used rimfire rifle platforms. Built around Ruger 10/22 magazine compatibility, it is well suited to shooters assembling a more stable and configurable rifle for rimfire competition, small-game hunting, training, or general range use. The chassis format replaces the limitations of a conventional stock with a more rigid aluminium structure, giving the action a consistent foundation that supports repeatable handling and a more deliberate shooting position.

This model is particularly useful for builders who want to shape the rifle around their own needs. AR-15 style grip compatibility allows the grip angle and size to be selected for comfort and trigger control, which matters when shooting from barricades, prone, or improvised field positions. The 142.00 mm forend length keeps the base compact, while the chassis still provides clearance for barrels up to 31.75 mm in diameter, making it suitable for heavier rimfire barrel profiles often chosen for accuracy-focused builds. At 998.00 g and 322.00 mm in length, it remains manageable as the starting point for a practical rifle setup.

Because this is an LSS Gen3 chassis base, its real strength is how it supports a modular build path. It is intended for shooters who want the core of the rifle to stay constant while the surrounding configuration evolves for hunting, tactical-style training, or competition use.

About MDT

MDT Sporting Goods was established in 2009 in Chilliwack, British Columbia, Canada. The company focuses on designing, manufacturing, and selling rifle chassis systems, magazines, buttstocks, and accessories for target shooting and hunting. Its product range also includes bipods, scope bases, and scope rings, giving MDT a strong presence in the broader rifle-support equipment category.

A notable part of MDT’s history is that it identifies the TAC21 as its first chassis, which reflects how central chassis design has been to the brand from the beginning. MDT states that its chassis, magazines, and accessories are developed with input from competitive precision shooters, and that emphasis shows in products built around modularity, adjustability, and practical rifle setup. For a product such as the LSS Gen3 chassis, that background is directly relevant: MDT’s expertise lies in turning factory rifle actions into more configurable shooting systems.
