MDT Field Stock Chassis, Ruger American LA

• Aluminum core construction: The MDT Field Stock Chassis uses an aluminium structure to give a more rigid foundation than a typical factory stock, helping the action stay consistently supported for steadier point of impact.
• AICS magazine compatibility: Support for AICS magazines makes it easier to configure the rifle for practical hunting use or longer range sessions, with broad magazine availability and straightforward reloads.
• M-LOK forend: The M-Lok forend allows lights, bipods, tripods and other accessories to be mounted where they are most useful, so the rifle can be adapted without bulky add-on parts.
• Adjustable fit: With a 343.00 mm to 368.00 mm length-of-pull range and an adjustable buttstock, the chassis can be set up for a more natural shooting position in field clothing or from supported positions.
• Built for long-action Ruger American rifles: This version is made for the Ruger American LA platform and accepts barrels up to 31.75 mm in diameter, giving the rifle a more stable, purpose-built hunting chassis layout.

About the MDT Field Stock Series

MDT announced the Field Stock on July 11, 2023 as a more accessible stock system for shooters who want to move beyond a factory stock without stepping into a full competition chassis. In MDT’s lineup, the Field Stock sits as a practical crossover option for hunting, competition, and casual long-range shooting, combining a familiar stock shape with chassis-style rigidity and accessory support.

A defining feature of the series is its aluminum V-block bedding system paired with an overmolded polymer body. In practice, that gives the rifle a more stable action interface while keeping the handling closer to a conventional field stock than a large tactical chassis. The series also includes an M-LOK forend, an adjustable cheek riser, and length-of-pull adjustment, so fit and accessory setup can be tailored to different rifles and shooting positions. MDT offers the Field Stock across a wide spread of centerfire and rimfire actions, and a left-handed version is also available for selected configurations.

About the MDT Field Stock Chassis, Ruger American LA

The MDT Field Stock Chassis, Ruger American LA is built for shooters who want a more stable and adaptable platform for a Ruger American long-action rifle while keeping the rifle suitable for real field use. Rather than turning the rifle into a heavy bench setup, this chassis focuses on improving support, fit and accessory mounting in a package intended for hunting. The 1406.00 g weight keeps it substantial enough to add rigidity, yet still appropriate for a rifle that may be carried over distance.

The chassis uses an aluminium structure and an adjustable buttstock, which matters because stock fit has a direct effect on head position, recoil control and repeatable shooting form. Its 343.00 mm to 368.00 mm length-of-pull adjustment helps the rifle fit different body sizes, shooting jackets or seasonal clothing. Up front, the 302.00 mm M-Lok forend gives room for a bipod, tripod interface or other accessories without forcing a fixed setup. That makes the rifle easier to configure for prone shooting, supported hunting shots or range practice.

Magazine flexibility is another practical advantage. Because the chassis is AICS Magazine Compatible, it opens the Ruger American LA platform to a widely used magazine pattern that is easy to source and familiar to many precision and hunting shooters. The design also accepts a maximum barrel diameter of 31.75 mm, which gives useful clearance for heavier barrel profiles than a basic factory stock typically allows. At 818.00 mm overall length and with a fixed, non-folding layout, it favors straightforward durability and a consistent shoulder position over added hinge complexity.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on products for shooters who want to improve rifle fit, modularity and consistency, with a catalog that includes rifle chassis systems, magazines, buttstocks, and accessories for target shooting and hunting. MDT also produces scope bases, rings and bipods, giving it a broad presence in the rifle-support category rather than in optics alone.

A notable part of MDT’s history is the TAC21, which the company identifies as its first chassis. MDT states that its chassis, magazines and accessories are developed with input from competitive precision shooters, and that background shows in the company’s emphasis on practical adjustability, magazine compatibility and modular mounting interfaces. Its head office remains in British Columbia, Canada, and its product range continues to center on rifle systems designed to bridge field use and precision shooting needs.
