Description
This is the suppressor-ready version of CZ's well-loved 457 Varmint, chambered in .22 WMR and wearing a 20.5 inch heavy barrel that comes threaded from the factory. The heavy profile is what makes this rifle tick. It keeps barrel harmonics steady and helps the gun shoot a wide range of .22 Mag loads well, whether you're ringing steel off a bench or walking fields after rabbits and foxes. The .22 WMR itself gives you a flatter trajectory and more punch downrange than a standard .22 LR, which is exactly why a lot of folks reach for it when they want a little more reach and terminal energy.
What Sets the 457 Varmint Apart
The barreled action sits in a Turkish walnut varmint stock with an American-style comb that lines you up behind a scope nicely, plus a wide flat forend that rides a sandbag or bipod like it was made for it. Laser-cut stippling on the grip and forearm gives you a sure hold in any weather. There are no iron sights here, which is normal for a varmint rig since it's built to wear glass. The receiver uses an integrated 11mm dovetail, so you mount rings directly without needing a separate base.
Running a Can on the CZ 457 Varmint Suppressor-Ready
The big draw with this particular model is the factory threaded muzzle, cut 1/2×28 to accept a suppressor or muzzle device. .22 Mag through a can is a genuinely enjoyable way to spend an afternoon, and having it done at the factory means clean, concentric threads and a cap that sits flush when you're running bare.
Trigger, Bolt, and the Swappable Barrel System
CZ gives the 457 a fully adjustable trigger you can tune for weight, creep, and over-travel, which is a big step up from most factory rimfires. The 60-degree bolt throw clears larger scope bells and cycles fast, and the push-to-fire two-position safety sits right where your thumb wants it. One of the smartest parts of the platform is the swappable barrel and stock system carried over from the 455, so down the road you can add a different caliber or barrel length without buying a whole new rifle. Feeding comes from a reliable 5-round polymer magazine.

Frequently Asked Questions
Is the CZ 457 Varmint .22 WMR barrel threaded?
Yes, this suppressor-ready model (02407) comes with a factory threaded muzzle in 1/2×28, which is the common pitch for rimfire suppressors and muzzle devices. A thread protector is included so the barrel looks finished when you're running it bare. Keep in mind the standard Varmint .22 WMR without the suppressor-ready designation is not threaded, so this model is the one to grab if a can is in your plans.
Does the CZ 457 Varmint come with iron sights?
No, it does not have iron sights. Like most varmint and target rifles, it's built to run optics, and the receiver features an integrated 11mm dovetail so you can mount rings directly without a separate base. The 60-degree bolt throw also helps clear larger scope bells with lower ring heights.
What kind of accuracy can I expect from the 457 Varmint in .22 Mag?
The heavy cold hammer forged barrel and fully adjustable trigger help this rifle shoot well across a variety of .22 WMR loads. Many owners report sub-MOA groups once they find the ammo their particular barrel likes best. Since .22 Mag is factory-only ammo, it's worth trying a few different loads to see what groups tightest in your rifle.
Can I swap calibers or barrels on the CZ 457?
Yes, the 457 uses the same user-swappable barrel and stock system carried over from the 455 platform. That means you can change barrel lengths or move to another rimfire caliber down the road without buying a whole new rifle. It makes the 457 one of the more flexible rimfire platforms you can own.
