Description
There is a reason the CZ 457 keeps coming up whenever people talk about serious rimfire rifles. This American Synthetic Suppressor-Ready version takes everything that made the 457 platform a favorite and wraps it in a package built for quiet work. The 20.5 inch cold hammer forged barrel wears 1/2×28 muzzle threads, and CZ holds tight chamber tolerances that make this rifle an excellent suppressor host. Squirrel hunting at first light, plinking with the kids, or stretching a .22 LR out past 100 yards, this thing handles all of it without complaint.
Built to Shrug Off the Weather
The synthetic stock borrows its lines and ergonomics from CZ's 557 American Synthetic, so it feels like a proper centerfire hunting rifle scaled to rimfire. Combine that stock with the black nitride finish on the metalwork and you get a rifle that does not care about rain, humidity, or getting tossed in the truck for a weekend at the cabin. At 5.4 pounds it carries easy all day, and the 5 round detachable polymer magazine is the same proven design CZ has been running for years.
What Sets the 457 Platform Apart
The action is machined from billet steel with 11mm dovetails cut directly into the receiver, so scope mounting is rock solid. CZ went with a 60 degree bolt throw instead of the old 90, which clears larger scope bells and lets you run lower rings. The trigger is fully adjustable for weight, creep, and over-travel, so you can tune it to your liking with a few minutes of work. There is also a two-position push-to-fire safety and an interchangeable barrel system, meaning you can swap this rifle to another rimfire chambering down the road without buying a whole new gun.
Topping Off Your CZ 457 American
This model ships without sights because it is meant to wear glass. Grab a set of 11mm rimfire rings or a dovetail-to-Picatinny adapter, mount a quality scope, and start finding out just how accurate a well-built .22 bolt gun can be. Add a can up front and you have a backyard-quiet setup that will get handed down for generations.

Frequently Asked Questions
Does the CZ 457 American Synthetic come with sights or a scope rail?
No iron sights on this one, and that is by design. The receiver has 11mm dovetails machined directly into the billet steel action, so you can mount rimfire rings straight to it or add a dovetail-to-Picatinny adapter if your rings require it. The 60 degree bolt throw also gives you extra clearance for scopes with larger ocular bells.
What suppressors will fit the CZ 457 Suppressor-Ready barrel?
The muzzle is threaded 1/2×28, which is the standard thread pattern for the vast majority of rimfire suppressors. Just about any .22 can on the market will spin right on. CZ also cuts the chamber to tight tolerances, which helps keep things consistent and quiet when running suppressed.
Is the trigger on the CZ 457 adjustable?
Yes, and it is one of the best features of the platform. The trigger adjusts for pull weight, creep, and over-travel, so you can dial it in to a crisp, light break that suits your shooting style. Most owners find they can get it tuned nicely with just a few minutes of adjustment.
Can I swap barrels on the CZ 457 to shoot other calibers?
You can. The 457 uses CZ's interchangeable barrel system, so with a barrel set and the right magazine you can convert this rifle to .22 WMR or .17 HMR. It is a nice way to get multiple rimfire chamberings out of a single action and stock.
