MDT ACC Elite CZ 457 Chassis – Black
The MDT ACC Elite 107957-BLK is our flagship competition chassis for the CZ 457.
Built for shooters who want absolute confidence in their equipment when the pressure is on, the ACC Elite combines exceptional rigidity, precise balance tuning, full-length ARCA support, and highly adjustable ergonomics into a chassis designed around serious PRS Rimfire, NRL22-style competition, positional shooting, and precision rimfire.
This is MDT's top-tier competition platform. It is designed for shooters building a CZ 457 around podium-level performance rather than simply replacing the factory stock.
At the end of the day, you know your gear isn't what is holding you back.

Built to Win
The ACC Elite sits at the top of MDT's competition chassis lineup and is engineered as a complete system around rigidity, balance, recoil control, and shooter interaction.
A strengthened forend, solid center section, and dedicated connector structure between the grip and buttstock help reduce unwanted flex when the rifle is loaded into a barricade, bag, or other support.
The result is a platform that settles naturally into position and remains predictable as the shooter moves through a stage.
19" ACC Elite Competition Forend
The ACC Elite uses a long, wide, and exceptionally rigid 19-inch competition forend designed to provide stability on barricades, bags, and unconventional support surfaces.
- Full-length integrated ARCA interface
- M-LOK accessory mounting
- Internal and external weight compatibility
- Wide, flat competition-oriented profile
- Included underside grip tape for added traction on bags and barricades
- Mounting provisions for compatible MDT Control Bridge and NV Bridge components
The full-length ARCA surface allows bipods, tripods, barricade stops, and other compatible support equipment to be positioned where they work best for the stage instead of forcing the shooter into one fixed mounting location.
Precision Balance Tuning
One of the defining advantages of the ACC Elite is the ability to tune the rifle's center of gravity around the barrel, optic, bipod, and shooting style.
Compatible MDT internal and external weights allow mass to be placed where it actually helps the rifle rather than simply making the build heavier.
A properly balanced rifle settles more naturally on a bag or barricade, requires less input from the shooter to stay level, and remains more predictable during transitions.
Elite-Level Rigidity
Competition stages routinely require the rifle to be loaded hard into barricades, bags, tank traps, rooftops, and other imperfect supports.
The ACC Elite chassis structure is built to resist twisting and bending under those conditions. Its reinforced construction helps maintain a consistent relationship between the shooter, action, barrel, and support surface throughout a stage.
For a CZ 457 being built as a serious match rifle, that structural rigidity is one of the major differences between a general-purpose chassis and a true flagship competition system.
SRS-X Elite Buttstock
The included MDT SRS-X Elite buttstock provides extensive tool-less adjustment so the rear of the rifle can be fitted around the shooter instead of forcing the shooter to adapt to the rifle.
- Adjustable cheek rest height
- Front and rear cheekpiece adjustment
- Adjustable length of pull
- Adjustable buttpad height
These adjustments help establish a natural position behind the optic and make it easier to reproduce the same head and shoulder placement from one shooting position to the next.
Vertical Grip Elite & Adjustable Thumb Rest
The MDT Vertical Grip Elite gives the shooter extensive control over trigger-hand placement.
The grip can be adjusted forward, rearward, and through its angle to create a more natural wrist position and cleaner trigger-finger alignment.
Combined with the adjustable M-LOK thumb rest and the ACC Elite connector structure, the system creates a consistent trigger-hand position that can be tuned around the individual shooter.
Barricade & Bag Performance
The ACC Elite is built around the realities of positional competition.
Its broad forend creates a stable interface with bags and props, while the included grip tape helps the rifle stay planted instead of sliding across the support surface.
The long ARCA interface also gives the shooter considerable freedom to position support equipment and adjust how the rifle interacts with the stage.
What Sets the ACC Elite Apart
The ACC Elite is more than an accessory-ready chassis. It is engineered as a complete competition system.
Compared with the ACC Premier Gen2, the Elite uses a longer, wider, and more competition-focused front section along with the SRS-X Elite buttstock, Vertical Grip Elite, advanced balance tuning, and additional structural reinforcement.
The ACC Premier Gen2 is an excellent chassis for shooters who want competition capability with more versatility. The ACC Elite is the step above it for the shooter whose priority is maximizing stability, control, and configurability on the clock.
The Flagship CZ 457 Competition Platform
The CZ 457 has become one of the dominant foundations for serious precision-rimfire builds, and the ACC Elite gives the action a chassis capable of supporting a full competition-focused rifle.
For PRS Rimfire and NRL22-style shooting, the combination of a rigid chassis, tunable balance, full-length ARCA, adjustable stock geometry, and competition-oriented ergonomics gives the shooter the tools needed to build the rifle around the stage instead of adapting the stage to the rifle.
