MDT LSS Gen3 Competitor Chassis System, Tikka T3/T3x LA

• Competition-focused forend: The Competitor configuration uses a 387.00 mm forend with both Arca and M-Lok interfaces, giving the rifle a stable support platform for bipods, tripods, barricade work, weights, and other match accessories.
• Modular LSS Gen3 architecture: The chassis is built around MDT’s action-mating base with interchangeable components, so the rifle can be configured around a specific discipline while keeping the familiar fit and handling of the system.
• XTN buttstock interface: The rear interface accepts compatible buttstock options, making it easier to tailor balance, length, and rear support characteristics to a competition rifle setup.
• AICS magazine compatibility: Support for AICS-pattern magazines gives access to a widely used magazine standard, which simplifies loadout planning for precision and practical shooting applications.
• AR-15 grip compatibility: The chassis accepts AR-15 style grips, allowing the shooter to choose grip angle and shape that better suit prone work, positional shooting, or personal ergonomics.

About the MDT LSS Series

The MDT LSS Gen3 series is a modular chassis family introduced in 2025 for shooters who want one rifle platform that can be adapted to different roles. Within MDT’s lineup, it sits as a flexible system for competition, hunting, tactical use, and general shooting, built around an action-specific chassis core rather than a one-piece fixed-format design. That approach lets the user choose the handguard and buttstock interface that best match the rifle’s purpose.

A defining characteristic of the series is its emphasis on practical modularity. MDT designed the LSS Gen3 so that handguards and buttstocks can be changed without affecting rifle zero, which matters for shooters who want to reconfigure a rifle for different stages, support methods, or carry requirements without rebuilding the entire setup. The series also accepts AR-style grips and uses an ambidextrous magazine latch, both of which support easier handling across a wide range of shooting positions. With dedicated Competition, Hunting, and Tactical forend options, the LSS Gen3 family is aimed at shooters who value a chassis that can be tuned around the job instead of forcing one layout to do everything.

About the MDT LSS Gen3 Competitor Chassis System, Tikka T3/T3x LA

The MDT LSS Gen3 Competitor Chassis System for Tikka T3/T3x LA is configured for shooters building a long-action rifle around match-oriented support and accessory use. Its 387.00 mm Competitor forend provides more usable mounting space and a steadier front-end feel than a minimal chassis layout, which is especially helpful when the rifle is used from barricades, tripods, bags, or bipods. The combination of Arca and M-Lok interfaces makes it easier to move quickly between support methods while still leaving room for accessories such as weights, rails, or barricade stops.

The chassis uses an aluminium construction that gives the rifle a rigid bedding platform and a more consistent foundation for precision shooting. For a Tikka T3/T3x long action, that matters in practice because the chassis is not just a stock replacement; it is the structural core that ties the action, magazine system, grip, and rear interface into one repeatable setup. AICS magazine compatibility keeps the rifle aligned with a common precision-rifle magazine standard, while the XTN buttstock interface leaves room to choose a rear section that suits the rifle’s balance and intended use.

AR-15 style grip compatibility is another practical advantage. Grip shape and angle have a direct effect on trigger reach and wrist position, particularly in prone and supported positions, so the ability to fit a preferred grip helps the rifle feel more natural over long strings of fire. Altogether, this chassis is aimed at competition-oriented shooters who want the familiar smoothness of a Tikka action in a platform built for modular support equipment and positional precision shooting.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on products for target shooting and hunting, with a catalog that includes rifle chassis systems, magazines, buttstocks, and related accessories. MDT identifies the TAC21 as its first chassis, which reflects how central chassis design has been to the brand from the beginning.

Today, MDT’s range also includes stocks, bipods, scope bases, and scope rings, but the company is best known for building modular rifle platforms around practical field and match use. MDT states that its chassis, magazines, and accessories are developed with input from competitive precision shooters, which helps explain the brand’s focus on adjustability, accessory mounting, and compatibility across different rifle actions. That background makes MDT a natural fit for shooters assembling precision and competition rifles around a dedicated chassis system.
