MDT ACC Elite Chassis System, CZ 457

• Competition-focused balance system: The MDT ACC Elite platform is built around rifle balance and weight tuning, helping the shooter settle the rifle on barricades, bags, and positional supports with less movement between shots.
• Full-length ARCA and M-LOK forend: The forend combines ARCA and M-LOK interfaces, making it easier to mount bipods, tripods, weights, and accessories exactly where they improve stability and handling.
• Adjustable fit architecture: With the XTN buttstock interface and compatibility with AR-15 style grips, the chassis supports a more personalized setup for trigger reach, rear support, and overall shooting comfort.
• Rigid aluminium construction: The aluminium chassis gives the rifle a stable bedding platform that supports consistent action fit and dependable handling during long practice sessions or match use.
• Built for practical rimfire precision: In the CZ 457 inlet, this chassis brings centerfire-style ergonomics and accessory mounting to a popular rimfire action, making it well suited to training and precision-rifle style competition.

About the MDT ACC Elite Series

The MDT ACC Elite series sits at the competition end of MDT’s chassis lineup and was introduced in December 2022. It was developed for precision-rifle competition and match use, where rifle balance, positional stability, and shooter fit matter as much as raw accuracy. A defining feature of the series is its full-length ARCA forend combined with a system for adjusting rifle weight, giving shooters more control over how the rifle behaves on barricades, tripods, and support bags.

The series also emphasizes fit and repeatability. MDT pairs the chassis with its SRS-X Elite buttstock and Vertical Grip Elite, both designed with multiple adjustment points so the rifle can be set up around the shooter rather than the other way around. The platform includes practical competition details such as an adjustable M-LOK thumb rest, an adjustable magazine latch, and an RRS Lock interface beneath the forend. A connector bar linking the grip to the buttstock and a reinforced forend underline the design goal: a rigid, highly configurable chassis for shooters who want a stable rifle with modern support and accessory interfaces.

About the MDT ACC Elite Chassis System, CZ 457

The MDT ACC Elite Chassis System, CZ 457 brings the ACC Elite competition concept to a widely used rimfire action, giving the rifle the feel and accessory support of a modern precision platform. For shooters using the CZ 457 for rimfire matches, structured training, or positional practice, this matters because the chassis allows the rifle to be set up much like a centerfire competition gun. That makes transitions, support-hand placement, and bag use more consistent from one discipline to another.

The chassis uses an aluminium construction and measures 950.00 mm in length, with a listed weight of 2767.00 g. In practice, that added mass is part of the point: a heavier competition chassis can reduce the tendency of a light rimfire rifle to shift off target during awkward positional shots. The Arca, M-Lok forend expands how the rifle can be configured, whether the goal is fast tripod attachment, bipod placement, or adding accessories and weights in useful positions along the chassis.

The rear of the chassis uses an XTN Interface, while the grip area accepts AR-15 Style Grips. That gives the shooter more freedom to tailor hand position and rear support geometry to personal preference. The chassis is also AICS Magazine Compatible, which supports the use of a common magazine pattern in precision-oriented setups. With a 34.29 mm maximum barrel diameter and a non-folding layout, this version favors rigidity and a straightforward match configuration over compact transport features.
