The MDT ACC Elite 107957-M81 is a flagship competition chassis for the CZ 457, combining a rigid aluminum platform, full-length ARCA interface, tunable balance system, SRS-X Elite buttstock, Vertical Grip Elite, and extensive competition-focused adjustability.
Finished in M81 Woodland custom Cerakote, this version adds a distinctive finish to one of MDT's most competition-focused rimfire chassis systems.
Built for PRS Rimfire, NRL22-style competition, positional shooting, long-range rimfire, and serious precision training, the ACC Elite is designed for shooters building the CZ 457 around match performance rather than general-purpose field use.
The M81 Woodland finish makes the 107957-M81 distinctly different from MDT's standard factory ACC Elite colors.
This chassis receives a custom Cerakote finish inspired by the classic M81 woodland camouflage pattern while retaining the full competition capability of the ACC Elite underneath.
For shooters building a premium CZ 457 and wanting something more distinctive than a standard Black, FDE, or Titanium Blue chassis, the M81 configuration gives the rifle a completely different character.
The ACC Elite sits at the top of MDT's competition-oriented CZ 457 chassis lineup.
Rather than simply replacing the factory stock, the ACC Elite is designed around the demands of positional competition: rigidity, balance, barricade stability, adjustable ergonomics, and rapid support-position changes.
For a CZ 457 being built specifically around PRS Rimfire or NRL22-style shooting, the ACC Elite provides the foundation for a highly developed match rifle.
The 107957-M81 is configured for the right-hand CZ 457.
The chassis provides a rigid aluminum foundation for the rimfire action while retaining the familiar factory CZ 457 magazine system.
It does not convert the rifle to a centerfire AICS magazine system.
The ACC Elite incorporates a full-length ARCA interface along the underside of the forend.
Compatible bipods, tripod clamps, barricade stops, and other ARCA-mounted accessories can be positioned where needed without adding a separate bolt-on rail.
For positional competition, that gives the shooter significantly more freedom to tune bipod and tripod placement around each stage.
The ACC Elite uses a long, wide forend designed specifically around competition shooting.
Its broad lower surface provides a stable footprint on bags, barricades, tank traps, rails, and other positional supports.
That added width helps the rifle settle more predictably on support surfaces and provides more usable space for weights and accessories.
One of the defining features of the ACC platform is the ability to deliberately tune the rifle's weight and balance.
Compatible internal and external weights can be positioned around the chassis to shift the balance point and increase stability.
For competition shooters, the goal is not simply adding weight. It is placing that weight where it helps the rifle remain stable on barricades and recover consistently between shots.
The ACC Elite uses MDT's SRS-X Elite buttstock, giving the shooter extensive control over rear-stock geometry.
Cheek height, length of pull, and buttpad position can be adjusted to establish a natural position behind the optic.
Those adjustments are particularly important in positional shooting where the rifle needs to fit the shooter consistently from prone, kneeling, standing, and improvised support positions.
The included MDT Vertical Grip Elite provides extensive adjustment of the shooter's firing-hand position.
The grip can be tuned around hand size and preferred trigger-finger placement, helping create a more relaxed and repeatable firing position.
A rigid connector structure between the grip area and rear chassis also contributes to the ACC Elite's overall stiffness under positional loading.
The ACC Elite includes an adjustable M-LOK thumb rest that allows the support or firing-hand position to be further tuned around the shooter.
Small ergonomic adjustments can make a meaningful difference during long match stages where repeatable hand placement and minimal unnecessary muscle tension matter.
The ACC Elite is designed to remain stable when the rifle is loaded into bags, barricades, and other match props.
The wide forend provides a large support surface, while the included underside grip material helps the rifle maintain contact with bags and barricades.
That combination makes the chassis particularly well suited to the rapid position changes common in PRS Rimfire and NRL22-style competition.
The ACC Elite forend is designed to accept compatible MDT Control Bridge and NV Bridge accessories.
These can provide additional control surfaces, accessory mounting, barrel coverage, and equipment positioning depending on the shooter's setup.
The chassis can therefore start relatively clean and be built into a much more specialized match configuration as needed.
The ACC Elite provides generous barrel clearance for the heavy profiles commonly used on precision CZ 457 rifles.
That makes it well suited to factory heavy-barrel configurations as well as custom CZ 457 builds using larger aftermarket match barrels.
The ACC Elite is at its best when the CZ 457 is being built around competition.
Full-length ARCA, tunable balance, a wide barricade surface, highly adjustable rear stock, competition grip geometry, and extensive accessory compatibility give the shooter substantial control over how the rifle behaves from different support positions.
It can also serve as a rimfire trainer for shooters who want their CZ 457 to more closely replicate the ergonomics and balance of a centerfire PRS rifle.
The ACC Premier Gen2 is an excellent competition-capable chassis, but the ACC Elite is the more developed flagship system.
The Elite adds a more substantial competition forend, greater ergonomic adjustment, the SRS-X Elite buttstock, Vertical Grip Elite, adjustable thumb support, and additional chassis reinforcement.
For shooters who want the highest-level MDT competition platform available for the CZ 457, the ACC Elite is the natural step up.
The Oryx provides an excellent value-oriented precision chassis for the CZ 457, but the two systems are designed for very different roles.
The Oryx focuses on straightforward precision and versatility.
The ACC Elite is built around competition balance, positional control, weight tuning, ARCA integration, and extensive shooter adjustment.
For a recreational or general-purpose precision build, the Oryx may be all the chassis needed. For a dedicated competition CZ 457, the ACC Elite offers considerably more room to tune the rifle.
