MDT ACC Premier Gen2 CZ 457 Chassis – Flat Dark Earth
Looking for a rifle chassis that can keep up with PRS competition, serious hunting, precision rimfire, and recreational shooting? The MDT ACC Premier Gen2 109725-FDE gives the CZ 457 a rigid, highly tunable foundation built around stability, balance, and shooter fit.
The ACC Premier Gen2 combines a reinforced aluminum chassis, full-length ARCA interface, adjustable stock geometry, and extensive weight and accessory tuning into a platform that can be configured around the way you actually shoot.
Whether the rifle is being built for a match stage, a field position, or a day at the range, the ACC Premier Gen2 gives the CZ 457 a solid foundation you can rely on.

Flat Dark Earth Finish
The Flat Dark Earth finish gives the ACC Premier Gen2 a practical, field-oriented look that works just as well on a competition rifle as it does on a hunting or recreational build.
It pairs naturally with black, stainless, and other common rifle components while retaining the same competition-focused function underneath: rigid construction, extensive balance tuning, and adjustable shooter fit.
Built for Stability, Balance & Flexibility
The ACC Premier Gen2 is fully tunable, allowing the shooter to adjust cheek riser height, length of pull, rifle balance, and accessory placement around the intended use of the rifle.
That flexibility matters on a competition rifle, where balance and repeatable positioning can affect movement through a stage, but it is just as useful on a hunting or recreational rifle where unnecessary weight and accessories can simply be left off.
The ergonomic design creates consistent contact points between the shooter and rifle, helping improve control from prone, barricade, tripod, bag-supported, and unsupported positions.
Gen2 Improvements Over Gen1
The second-generation ACC Premier chassis builds on the original ACC concept with practical changes focused on rigidity, handling, action support, and accessory configuration.
- Reinforced 15" front section adds rigidity for barricade, prone, and natural-support shooting.
- Shortened front length improves handling with shorter barrels and helps keep the rifle balanced during faster transitions.
- Integrated tall barricade stop provides a consistent contact point on props, barricades, and uneven terrain.
- Multiple internal and external mounting channels allow weight and accessory placement to be tuned without sacrificing chassis strength.
- Maximum barrel diameter of approximately 1.25" provides clearance for heavy-contour competition and precision barrels.
Purpose-Built for PRS & Precision Rimfire
For PRS and precision-rimfire shooters, the ACC Premier Gen2 provides a stable and predictable platform for repeatable positioning and smooth stage movement.
The reinforced 15-inch forend creates a wide, stable surface for bags and barricades, while the integrated ARCA interface makes it easy to position bipods, tripods, and other support equipment exactly where it works best.
Weight can be added or repositioned to tune the rifle's center of gravity, helping the rifle settle naturally on barricades and bags instead of fighting the shooter.
Full-Length ARCA Interface
The bottom of the forend incorporates a full-length ARCA interface rail, eliminating the need to bolt a separate rail to the chassis.
This provides a continuous mounting surface for ARCA-compatible bipods, tripod clamps, and other support equipment while allowing accessories to be repositioned quickly as shooting conditions change.
M-LOK mounting locations provide additional space for weights and accessories while leaving the primary ARCA surface available for support equipment.
Competition Capability Without Becoming One-Purpose
The ACC Premier Gen2 is built around competition use, but it does not have to become a one-purpose match rifle.
For hunters, the chassis provides rigid and repeatable support while allowing unnecessary weights and accessories to be removed. The shooter can configure the rifle for the actual job instead of carrying equipment that adds no value in the field.
For recreational shooting, the adjustable cheekpiece, length of pull, and accessory placement make it easy to create a comfortable setup for extended range sessions and precision practice.
Tune the Rifle's Balance
One of the defining features of the ACC platform is its ability to be tuned around the rifle and shooter rather than forcing the shooter to adapt to a fixed configuration.
Internal and external weight mounting locations allow compatible MDT weights to be positioned where they provide the most benefit.
The goal is not simply to make the rifle heavier. It is to place weight where it helps the rifle remain stable, track consistently, and sit naturally on a bag or barricade.
Adjustable Shooter Fit
The ACC Premier Gen2 provides adjustable stock geometry so the rifle can be fitted around the shooter, optic, and shooting position.
- Adjustable cheek riser height helps establish consistent eye alignment behind the optic.
- Adjustable length of pull allows the rifle to fit different shooters and shooting positions.
- Ergonomic hand support provides a consistent contact point for better control.
- Modular accessory placement allows the rifle to be configured for competition, hunting, or range use.
CZ 457 Fitment
The 109725-FDE is designed specifically for compatible right-hand CZ 457 rifles and retains the CZ 457 magazine system.
The combination of the CZ 457 action and ACC Premier Gen2 chassis creates a highly configurable precision-rimfire platform suited to competition, positional training, hunting, and serious range use.
