MDT ACC Premier Gen 2 Chassis System, Ruger American - Rimfire

• Adjustable Core Competition layout: The ACC Premier Gen 2 chassis is built around balance tuning, letting shooters place weight where it helps the rifle settle more naturally on barricades, bags, and positional supports.
• 15-inch competition forend: The long forend gives the rifle a stable support surface and more room for tripod, bipod, and hand placement, which is especially useful in precision-rifle and tactical stages.
• Arca and M-LOK interface: With an integrated accessory-ready forend, the chassis supports fast mounting of competition accessories, rails, and weights without forcing a fixed setup.
• Aluminium chassis construction: The rigid aluminium body helps maintain consistent action support while keeping the platform durable enough for regular match use and transport.
• Broad shooter-fit compatibility: The XTN buttstock interface, AR-15 style grip compatibility, and adjustable length-of-pull range make it easier to configure the rifle around shooting style, body size, and equipment.

About the MDT ACC Premier Series

MDT ACC Premier stands for Adjustable Core Competition, and the series is built for shooters who want a chassis system centered on balance control rather than a fixed rifle feel. In MDT’s lineup, it sits as a competition-focused platform for precision-rifle use, combining a rigid chassis structure with a layout that accepts both internal and external weights so the rifle can be tuned to the shooter, stage type, and support method.

The GEN2 update introduced for 2024 continues that approach with a 15-inch forend and an accessory-ready design that supports modern match setups. M-LOK attachment points allow the chassis to accept compatible accessories and weight kits, while the long forend gives shooters more usable space for barricade work, bag placement, and tripod mounting. MDT developed the ACC Premier concept with input from competitive shooters, and that shows in the way the series prioritizes balance, support-hand placement, and modularity over unnecessary bulk. The result is a chassis family aimed squarely at precision-rifle competition and tactical-style shooting where rifle control, repeatable positioning, and adaptable setup matter as much as raw action compatibility.

About the MDT ACC Premier Gen 2 Chassis System, Ruger American - Rimfire

The MDT ACC Premier Gen 2 Chassis System for the Ruger American Rimfire brings a competition-oriented chassis format to a popular rimfire action, making it a strong fit for shooters training for centerfire precision disciplines, building a match-ready rimfire rifle, or setting up a stable platform for tactical-style practice. Its 381.00 mm forend length gives the rifle a long, supportive front section that works well on bags, barricades, and tripods, while the Arca and M-Lok forend keeps the setup flexible for accessories and balance tuning.

The chassis is made from aluminium, which gives the action a rigid mounting structure and helps the rifle feel more planted during positional shooting. At 2359.00 g, it adds the kind of mass many competition shooters want because extra weight can calm movement, reduce wobble, and make transitions between props more controlled. The chassis also accepts a maximum barrel diameter of 31.75 mm, leaving room for heavier-profile barrels often chosen for rimfire precision builds.

Fit and configuration are equally important here. The 318.00 mm to 343.00 mm length-of-pull range helps adapt the rifle to body size, shooting position, and clothing layers, while the XTN buttstock interface opens the door to compatible rear-end setups. Compatibility with AR-15 style grips and MDT pistol grips lets shooters choose grip angle and shape to suit prone or positional work. With AICS magazine compatibility and an application focus on competition and tactical use, this chassis is designed to turn the Ruger American Rimfire into a more stable, more configurable precision platform.
