MDT ACC Premier Gen2 Chassis Base, Ruger 10/22

• Competition-focused balance system: The MDT ACC Premier Gen2 chassis is built around adjustable weight placement, letting shooters tune rifle balance for steadier positional shooting and more predictable handling on barricades and props.
• 15-inch forend with ARCA and M-LOK: A long, rigid 381.00 mm forend gives ample support-hand placement and accessory space, while the Arca, M-Lok layout makes it easier to add bipods, weights, rails, and match accessories without changing the rifle’s core setup.
• Aluminium chassis construction: The Aluminium body provides the stiffness needed for consistent action support while keeping the system durable enough for repeated transport, match use, and frequent accessory changes.
• XTN buttstock interface: The XTN Interface gives this chassis broad compatibility with suitable buttstock options, making it easier to configure the rifle for length of pull, cheek support, and overall fit to the shooter’s position.
• Built for modern rimfire competition: Designed for the Ruger 10/22 platform and intended for Competition use, this chassis brings centerfire-style ergonomics and accessory mounting to a rimfire rifle often used for NRL22 and precision practice.

About the MDT ACC Premier Series

ACC stands for Adjustable Core Competition, and that name describes the purpose of the series clearly. The MDT ACC Premier line sits in MDT’s competition-oriented chassis range and was developed for shooters who want to tune rifle balance, support placement, and overall ergonomics around positional precision shooting rather than general field carry. MDT updated the ACC Premier GEN2 for 2024, carrying over the series focus on modular balance control while refining the layout for modern match use.

A defining feature of the series is its 15-inch forend, which combines a long support surface with mounting space for accessories and weights. The design accepts both internal and external weights, allowing shooters to shift mass where it helps the rifle settle best on bags, barricades, and improvised supports. MDT also built the series with input from competitive precision shooters, which shows in the emphasis on repeatable handling, accessory compatibility, and a layout that supports match-driven rifle setups. M-LOK attachment points on the forend expand the chassis’ adaptability for weights and other accessories, making the ACC Premier series a practical choice for shooters building a rifle around balance tuning and stable positional performance.

About the MDT ACC Premier Gen2 Chassis Base, Ruger 10/22

The MDT ACC Premier Gen2 Chassis Base, Ruger 10/22 adapts the ACC competition concept to one of the most widely used rimfire platforms. For shooters building a match-oriented 10/22 for disciplines such as rimfire precision competition, the value of this chassis is not only in replacing the factory stock, but in giving the rifle the geometry, mounting options, and balance characteristics normally associated with centerfire competition systems. That makes the familiar Ruger 10/22 easier to configure for barricade work, prone stages, and supported positional shooting.

The chassis uses a 381.00 mm forend with Arca, M-Lok compatibility, which is especially useful on a competition rimfire. An ARCA-ready layout speeds up bipod and tripod positioning, while M-LOK slots leave room for weights and other accessories that help tune the rifle around a preferred stage style. The Aluminium construction adds the stiffness expected from a precision chassis, helping the action sit in a more stable structure than a conventional stock while standing up well to repeated transport and accessory changes.

This model also supports practical customization. The XTN Interface opens the door to compatible buttstock configurations, and AR-15 Style Grips let shooters choose a grip angle and shape that suits their trigger hand position. With support for a 31.75 mm maximum barrel diameter, the chassis also accommodates heavier rimfire barrel profiles often chosen for stability and heat management during extended strings. At 1633.00 g and 610.00 mm in length, it is clearly configured for competition use, where stability, accessory support, and repeatable rifle fit matter more than minimum carry weight.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company designs, manufactures, and sells rifle chassis systems, magazines, buttstocks, and accessories for target shooting and hunting, with a product range that also includes bipods, scope bases, and scope rings. MDT identifies the TAC21 as its first chassis, an early product that helped define the company’s direction in modular rifle support systems.

MDT is particularly well known for chassis and accessory systems developed with input from competitive precision shooters, which is directly relevant to products such as the ACC Premier. That background shows in the company’s focus on modularity, fit adjustment, and support for modern match shooting techniques. Alongside chassis systems, MDT also produces scope bases machined from 6061-T6 aluminum to MIL-STD-1913 and STANAG 4694 specifications, reflecting a broader emphasis on precision-machined shooting equipment.
