Description
The MDT ACC Elite stands apart in the rimfire competition space as a full-system platform designed specifically for the demands of NRL22 and PRS Rimfire matches. This chassis combines the ergonomics and modularity of centerfire competition rifles into a purpose-built CZ 457 package finished in Titanium Blue Cerakote.
19-Inch Forend with Full-Length ARCA Rail
The oversized 19-inch M-LOK compatible forend provides plenty of contact surface for barricade and bag shooting, while the integrated full-length ARCA rail underneath runs the entire length for seamless bipod mounting and accessory attachment. This generous footprint gives you real estate to work with on competition stages, and the wide, rigid design naturally settles into position on props and bags without shifting.
Tunable Weight System for Match Performance
What makes the Elite chassis truly competitive is the customizable weight management system. Interior and exterior weight pockets let you add up to 9 additional pounds throughout the buttstock, barrel channel, and forend, allowing you to achieve perfect balance and tune your rifle to your exact specs. Slide interior weights in and out without removing your barreled action, or adjust exterior M-LOK weights between stages to dial in your setup. This ability to fine-tune weight distribution directly translates to faster target settling and better recoil control when you need it most.
Fully Adjustable SRS-X Elite Buttstock
The included SRS-X Elite buttstock gives you toolless control over length of pull, cheek riser height, and buttpad position to dial in your natural shooting position. Length of pull ranges from 12.25 to 14.75 inches, covering a wide range of shooter builds. The rigid aluminum construction paired with soft neoprene cheek rest provides both comfort and repeatability, and integrated M-LOK slots let you add accessories like bag riders without additional modification.

Frequently Asked Questions
Can I adjust the weight on the ACC Elite CZ457 without removing the barreled action?
Yes, one of the key advantages of the ACC Elite system. Interior forend weights can be added or removed by simply removing the forend cap and sliding them in place without disturbing your action or barrel. External M-LOK weights are even quicker to swap between stages for balance tuning.
What makes the Elite version different from the Premier Gen 2?
The ACC Elite features a longer 19-inch forend versus the Premier Gen 2's 15-inch design, providing more stability on barricades and bags. The Elite also has expanded weight compatibility for more precise balance options and a wider, thicker front section for increased rigidity during competitive shooting.
Is the SRS-X Elite buttstock tool-free to adjust?
Mostly, yes. Length of pull, cheek riser height, and buttpad position can all be adjusted with intuitive knobs. Once you dial in your position, you lock everything down with included thumb screws or set screws. The chassis comes with tools stored magnetically under the cheek rest for on-the-go adjustments.
Will this chassis work with my existing CZ 457 rifle?
This chassis is specifically designed as a drop-in replacement for CZ 457 actions. Your barreled action will bed directly into the aluminum chassis with recoil lugs and mounting screws. It's a straightforward installation without gunsmithing required.
