MDT Chassis Field Stock CZ 457 Snow White 108669-WHT

The MDT Field Stock in Snow White gives the CZ 457 a sharp, clean appearance without sacrificing the conventional shoulder and grip geometry many shooters prefer. It is a useful middle ground between the original factory stock and a dedicated competition chassis: familiar handling for a field rifle, with more control over fit for range work and rimfire matches. Paired with black optics and controls or a stainless match barrel, the white finish makes the rest of the build stand out.

Inside the polymer exterior is a 6061 aluminum core with MDT’s V-block bedding interface. The action seats against the aluminum bedding surface while the barrel is allowed to free-float within MDT’s specified channel. The polymer shell offers a warmer contact surface than exposed aluminum in cold conditions. Snow White is a solid light finish, not the multi-tone Arctic Snow camouflage used on some other MDT chassis; that distinction matters when choosing matching components.

A Better Fit Behind the Scope

Stock fit changes how comfortably the shooter gets behind a riflescope. MDT includes an adjustable cheek riser and a spacer-adjustable length of pull, so the stock can be set for a natural eye position and comfortable shoulder placement. Its forend carries M-LOK accessory mounting locations, while front and rear sling-swivel studs accommodate familiar sling and bipod setups. If you already have a compatible sling-stud bipod, you can start with that instead of buying an ARCA system just to make the rifle usable.

The 108669-WHT is the CZ 457 inlet, not a universal stock or a Remington-pattern AICS conversion. It retains factory-pattern CZ rimfire magazines. MDT also specifies an 18-inch or longer barrel and a maximum CZ 457 barrel diameter of .920 inch for this stock. Those limits matter when choosing a match barrel: not every heavy-contour 457 barrel is a suitable choice. A stock or chassis is only part of the rifle, so verify your actual barrel diameter, action configuration and component fit before selecting a new configuration.

Running a bigger barrel? If your CZ 457 has a 1.00-inch, 1.18-inch or other oversized match barrel, the Field Stock’s .920-inch limit makes this the wrong stock for that setup. Instead, compare the MDT ACC Premier Gen2 CZ 457 or the MDT ACC Elite CZ 457 in Arctic Snow. Both offer a competition-oriented chassis layout worth exploring for a heavy-barrel build; confirm clearance for your exact barrel contour before ordering.

Pair It With

Small upgrades can complement the stock without crowding the build. The Pete’s Pillars stainless extended cocking indicator replaces the original polymer-style indicator, the PP457FP-T reshaped-tip firing pin is a precision replacement intended for suitable .22 LR configurations, and the 12 oz CZ 457 trigger spring is an option for experienced owners working with the factory trigger. These are independently sold components, not parts included with the Field Stock.

Barrels & Triggers That Suit the Field Stock

For a compatible .22 LR setup, compare .900-inch Lilja barrels at lengths of 21 inches or more, along with Timney trigger options. These are separate upgrades; verify chambering, barrel fit and installation requirements before ordering.

We like the way a traditional stock lets a nice barrel remain the center of attention. For a .22 LR build, the Lilja 21-inch .900 match barrel and 23-inch .900 version fit the dimensional direction MDT describes for this stock. By contrast, a 1.00-inch or 1.18-inch competition barrel would exceed the Field Stock’s listed .920-inch limit. If your rifle already has a compatible barrel, an updated Timney straight-shoe CZ 457 trigger or curved-shoe trigger provides another route to refining the rifle’s controls without changing its overall character.

Optics, Support & Magazines

Finish the Shooting Setup

Keep the original CZ 457 magazine format. Add an appropriate 11 mm dovetail-to-Picatinny scope rail and a bipod that actually matches the Field Stock’s sling stud or M-LOK interface. ARCA-only accessories require a suitable separately installed ARCA interface.

The simplest approach is to begin with what you already use. If your CZ 457 needs a scope base, our Pete’s Pillars 15 MOA rail and Area 419 15 MOA rail are two distinct options for its factory dovetail. A CZ factory 10-round .22 LR magazine or 5-round version keeps feeding hardware specific to the rimfire platform. For front support, compare the MDT GRND-POD M-LOK with the Magpul sling-stud bipod based on the interface you want to use; an ARCA-only bipod does not attach directly to the stock without the proper adapter.

When You Want More Chassis

From Field Stock to ACC Premier Gen2

The ACC Premier Gen2 is the direct step into a fully competition-oriented CZ 457 platform: integrated ARCA, a 15-inch forend, substantial accessory flexibility and provisions for weight tuning. The Arctic Snow ACC Elite and Oryx below also offer snow-themed finishes, but they are different chassis systems, not interchangeable Field Stock parts.

The Next Level

Ready for the ACC Premier Gen2?

The Field Stock is a comfortable, capable way to shoot the CZ 457. But if your plans lean toward NRL22, PRS rimfire or a purpose-built positional rifle, the MDT ACC Premier Gen2 for CZ 457 is a substantial next step. Its 15-inch aluminum forend, full-length integrated ARCA interface, barricade stop and tunable weight system are built around competition support and rifle balance. Choose Charcoal Green or FDE if you prefer either color; Snow White is not offered as an ACC Premier Gen2 finish in the linked selections. The ACC Premier Gen2 is an alternative chassis, not an accessory that installs onto the Field Stock.
