MDT ACC Elite Chassis Base, CZ 457

• Competition-focused chassis layout: The MDT ACC Elite platform is built for match shooting, giving the CZ 457 a more stable, purpose-driven foundation for positional work, barricades, and prone stages.
• Full-length Arca and M-Lok forend: The Arca, M-Lok forend makes it easier to move bipods, tripods, weights, and other accessories exactly where they are needed for balance and stage setup.
• Rigid aluminium construction: The aluminium chassis adds stiffness and consistency, helping the rifle maintain a repeatable interface between action and stock while standing up to regular range and match use.
• Broad fitment flexibility: With an XTN buttstock interface and compatibility with AR-15 style grips, the chassis supports a more tailored setup for shooter fit, control, and preferred ergonomics.
• Built around practical competition needs: AICS magazine compatibility and support for a 34.29 mm maximum barrel diameter make this chassis suitable for rimfire precision builds that use match-oriented accessories and heavier barrel profiles.

About the MDT ACC Elite Series

MDT introduced the ACC Elite chassis in December 2022 as a competition-focused series for shooters who want a more refined match platform than a general-purpose chassis. Within MDT’s lineup, the ACC Elite sits squarely in the precision-rifle competition space, with design priorities centered on balance, fit, and stage efficiency rather than field carry weight. It is intended for match use, where small gains in rifle control and shooter comfort matter over long strings of fire.

A defining trait of the series is its full-length ARCA forend combined with a system for adjusting rifle weight, allowing shooters to tune balance for barricades, bags, and tripod-supported positions. The series also uses the SRS-X Elite buttstock and Vertical Grip Elite, both built with multiple adjustment points so the rifle can be fitted more precisely to the shooter. MDT also equips the platform with details that matter in practical use, including an adjustable M-LOK thumb rest, an adjustable magazine latch, an RRS Lock interface beneath the forend, and a strengthened forend with a connector bar linking the grip area to the buttstock for added rigidity. The series is offered for several popular actions, including the CZ 457.

About the MDT ACC Elite Chassis Base, CZ 457

The MDT ACC Elite Chassis Base, CZ 457 brings the ACC Elite competition concept to one of the most popular rimfire precision platforms. For a CZ 457 build intended for NRL22-style matches, training, or technical target shooting, this chassis provides a more competition-oriented interface than a conventional stock. Its aluminium construction helps create a rigid foundation, which is valuable when the goal is repeatable action fit, stable support on bags or barricades, and consistent handling from stage to stage.

The chassis is configured around practical adjustability and accessory support. The Arca, M-Lok forend gives the rifle a versatile front end for mounting tripods, bipods, weights, and other accessories while also making it easier to shift support positions quickly during a course of fire. The XTN buttstock interface opens the door to a competition-style rear setup, while AR-15 style grip compatibility lets the shooter choose a grip angle and shape that better suits trigger control and hand position. For rimfire match rifles that use heavier barrels, the 34.29 mm maximum barrel diameter is an important fit detail, and AICS magazine compatibility supports a magazine format widely used in precision rifle setups. At 1360.00 g and 683.00 mm in length, the chassis is clearly aimed at stability and match utility rather than minimum carry weight.
