Best CZ 457 Chassis & Stocks 2026

The CZ 457 uses a proprietary rimfire mini-action footprint, so a CZ 457 chassis has to be cut specifically for it. It is not an AICS inlet and not a Remington 700 inlet, which means the huge centerfire chassis market is closed to you. Every product in this guide is a dedicated CZ 457 inlet, and every one of them feeds the rifle's factory rimfire magazine rather than converting it to a detachable AICS box.

That matters because most chassis marketing copy is written for centerfire rifles. When a product page talks about AICS feeding, 10-round polymer magazines, or short-action bedding, it is describing a different rifle. Compare that to a centerfire bolt gun like the Ruger American Gen 2, where magazine architecture follows the chambering and AICS chassis genuinely are on the table. On the 457 the magazine question is already settled: you keep the factory mags.

The second thing to check is barrel clearance. Both Boyds stocks are cut for the factory barrel channel rather than a heavy contour, and Boyds notes that a .920 inch barrel requires opening that channel. Measure your barrel before you order, because a laminated stock that has been opened up for a bull barrel cannot be put back.

Buy a chassis if you want rigidity, modular mounting, and adjustment; buy an aftermarket stock if you want a better shooting platform at the lowest cost. An aluminum chassis like the KRG Bravo or Grey Birch La Chassis puts a metal spine under the action and gives you M-LOK, ARCA, and adjustable geometry, which is what rimfire match shooting rewards. A replacement stock like the Boyds Pro Varmint gives you a broad, stable forearm and a more vertical grip for a fraction of that.

The honest dividing line is mounting hardware. If you shoot off bags, barricades, and a tripod, the integrated ARCA rail on the Grey Birch is worth the price step on its own, and the same logic drives the chassis choices in our PRS rifle build guide where a CZ 457 is a common understudy for the centerfire match gun. If you shoot from a bench, prone, or field positions with a sling and a bipod stud, a laminated Boyds stock covers you and leaves budget for glass and ammunition.

Weight is the other axis. The Grey Birch is 37 oz and the KRG Bravo is 3.1 lb, while the WOOX Furiosa runs 4.4 to 5.7 lb depending on furniture material. On a rimfire trainer that mirrors a heavy centerfire rig, that extra mass is a feature. On a walking squirrel or NRL22 field gun it is not.

A chassis is the highest-impact CZ 457 upgrade because it fixes the action-to-shell interface, but it only pays off once the rest of the rifle is honest. The factory 457 barrel and trigger are already good, which is why stock and chassis work sits at the top of the list rather than behind a barrel swap. Get the action into a rigid, repeatable shell first, then spend on glass.

Adjustment range matters more than material spec. A comb that puts your eye behind the scope without neck strain does more for your groups than an alloy upgrade, and it is why the Boyds At-One earns its place against far more expensive shells: push-button comb height and a 12.5 to 14 inch length of pull is real fit adjustment at a laminated-stock price. The WOOX Exactus does the same thing with a forged AA7075 monoblock hidden inside a traditional outline.

Bolt-action platforms reward this order of operations generally, not just on the 457. The same sequence of rigid shell, then fit, then optic drives our Tikka T3x upgrade path. And if you are still choosing the rifle itself rather than the shell, our best .22 LR rifle guide covers where the CZ 457 sits against other precision rimfire options.

To see how a shell, optic, and mount stack up before you spend, run the parts through the rifle builder or compare specs side by side in the component catalog.
