MDT LSS Gen3 Competitor Chassis System, Remington 700 SA

• Competition-focused chassis layout: The LSS Gen3 Competitor Chassis System is built for match use, giving a stable rifle foundation that supports consistent positional shooting and repeatable handling on barricades and props.
• Aluminium construction: Its aluminium chassis body adds rigidity over a conventional stock, helping the action sit in a more stable platform for predictable accuracy and long-term durability.
• Arca and M-Lok forend: The integrated Arca, M-Lok forend makes it easier to attach tripods, bipods, weights and other accessories, while also speeding up transitions between supported shooting positions.
• AICS magazine compatibility: Support for AICS-compatible magazines gives access to a widely used magazine pattern, which is practical for competition rifles where reliable feeding and easy magazine changes matter.
• Broad furniture compatibility: With an XTN buttstock interface and AR-15 style grip compatibility, this chassis can be configured around shooter fit and preferred ergonomics instead of forcing a fixed setup.

About the LSS Gen3 Series

The LSS Gen3 series represents MDT’s modern chassis approach for shooters who want a rifle platform that is lighter and more modular than a traditional stock, while still offering the control and accessory support expected from current precision rifle equipment. Within MDT’s lineup, the series sits as a practical bridge between compact chassis design and competition-oriented configurability, making it relevant for both target shooting and field use.

A defining trait of the LSS Gen3 family is its emphasis on modular interfaces. Rather than locking the rifle into one fixed format, the series is built to accept common grip and buttstock standards, allowing the shooter to tailor fit, balance and control. The design also reflects the way modern rifles are actually used, with forends that support accessories and positional shooting aids. In use, that means a chassis that can be adapted for match stages, supported prone work or a more streamlined hunting-oriented build, depending on the exact model and furniture chosen.

About the MDT LSS Gen3 Competitor Chassis System, Remington 700 SA

The MDT LSS Gen3 Competitor Chassis System, Remington 700 SA is configured around the short-action Remington 700 footprint and is intended for shooters who want a competition-ready chassis with broad setup flexibility. Its role is not simply to replace a stock, but to provide a more rigid and more adaptable rifle foundation for precision shooting disciplines where consistency, balance and accessory mounting all affect stage performance.

The chassis uses an aluminium body to create a stable bedding platform and durable structure. In practical terms, that helps the rifle maintain a more consistent feel under recoil and through repeated use, while also standing up well to transport, match handling and frequent accessory changes. The 387.00 mm forend is set up with both Arca and M-Lok interfaces, which is especially useful on a competition rifle: Arca simplifies tripod and support mounting, while M-Lok provides room for rails, weights and other add-ons without forcing a single layout.

The rear of the chassis is equally focused on configurability. The XTN buttstock interface allows the rifle to be paired with compatible buttstocks to suit length of pull and rear support preferences, while AR-15 style grip compatibility lets the shooter choose grip angle and shape to match their firing position. Combined with AICS magazine compatibility, the result is a chassis system that fits naturally into modern precision rifle setups and supports efficient magazine changes, stable supported shooting and a rifle balance that can be tuned around the shooter’s discipline.

About MDT

MDT Sporting Goods was established in 2009 and grew from its beginnings in Chilliwack, British Columbia, Canada. The company focuses on rifle chassis systems and related equipment for target shooting and hunting, with a catalogue that includes chassis, stocks, magazines, bipods, scope bases and scope rings. MDT identifies the TAC21 as its first chassis, which reflects how central chassis development has been to the brand from the start.

MDT’s product development is closely tied to practical shooting use. The company states that its chassis, magazines and accessories are developed with input from competitive precision shooters, which helps explain the strong emphasis on modularity, fit and support for modern rifle accessories across its lineup. That background makes MDT particularly relevant in the precision rifle and competition chassis category.
