Description
There is a reason the CZ 457 keeps coming up whenever rimfire guys talk about their favorite bolt guns. This American Synthetic version in .22 WMR takes everything that made the platform a hit and wraps it in a package built for real weather and real field time. The black synthetic stock borrows its lines from CZ's 557 American Synthetic, and combined with the nitride finish on the metalwork, this rifle shrugs off rain, snow, and truck-gun abuse that would have a walnut-stocked rifle looking rough in a season or two.
Built to Run Quiet
The 20.5 inch cold hammer forged barrel comes threaded 1/2×28 from the factory, so screwing on a can is about as simple as it gets. No adapters, no gunsmith trip. CZ machines these chambers to tight tolerances, which is a big part of why the 457 has earned a reputation as one of the better suppressor hosts in the rimfire world. Paired with .22 WMR, you get a flat-shooting round with plenty of punch for varmints and small game out well past typical rimfire distances.
The 457 Action Earns Its Keep
The receiver is machined from billet with 11mm dovetails cut directly into it, so mounting rings or a rail is solid and simple. There are no iron sights on this one because it was always meant to wear glass. The bolt runs a short 60 degree throw that clears low-mounted scopes and cycles fast, the trigger is fully adjustable so you can tune it to your liking, and the two-position push-to-fire safety is intuitive without getting in your way. You also get CZ's interchangeable barrel system, meaning this same action can swap to other rimfire chamberings down the road with a barrel set.
Why the CZ 457 American Synthetic Makes Sense
At around 5.4 pounds bare, it carries easy on long walks after squirrels or prairie dogs, and the detachable 5-round magazine keeps reloads quick. This is the kind of rifle that ends up being the one you grab most, whether it is wearing a suppressor on a quiet morning hunt or punching tight groups off the bench.

Frequently Asked Questions
Can I mount a suppressor directly on the CZ 457 American Synthetic?
Yes, the muzzle comes threaded 1/2×28 from the factory, which is the standard pitch for most rimfire suppressors. No adapters or gunsmithing needed, just thread on your can and go. CZ's tight chamber tolerances also help keep things running clean and consistent when shooting suppressed.
Does the CZ 457 come with sights or a scope rail?
This model ships without iron sights because it was designed to be run with an optic. The receiver has 11mm dovetails machined directly into the billet action, so you can mount rings or a rail solidly without drilling anything. Just make sure the rings or base you pick up are 11mm dovetail compatible, not standard Picatinny, unless you add an adapter rail.
Can I swap this 457 to a different caliber later?
Yes, the 457 platform uses CZ's interchangeable barrel system, so you can convert this rifle to .22 LR or .17 HMR with a barrel set and the appropriate magazine. It is a simple swap that only takes basic tools. That flexibility is one of the biggest reasons the 457 series has such a loyal following.
Is the trigger on the 457 American Synthetic adjustable?
It is fully adjustable, so you can dial in the pull weight to suit your preference. Out of the box it is already a clean, crisp trigger, but having the ability to fine-tune it is a nice bonus for precision work or hunting. It is one of the standout features that separates the 457 from most rimfires in its class.
