Description
One rifle that fits everybody in the house is a tall order, but the CZ 457 AT-ONE Varmint comes about as close as it gets. The Boyds AT-ONE laminate stock adjusts length of pull from 12.5 to 14.25 inches with a simple push button, and the comb rises up to 5/8 inch the same way. That means a smaller framed shooter can run it comfortably in the morning and you can stretch it back out for yourself in the afternoon, no tools required. The laminate itself is stiff and stable, which is exactly what you want under a rifle built for tight groups.
A Heavy Barrel That Earns Its Keep
CZ hangs a cold hammer forged 16.5 inch heavy barrel on this one, finished in black nitride and threaded 1/2×28 at the muzzle. Spin on a suppressor and this thing becomes a genuinely pleasant backyard and range companion, and the short bull barrel profile keeps things stiff for consistent accuracy. The 1:16 twist handles standard .22 LR fare well, and owners regularly report excellent results with quality match ammo out to 100 yards and beyond. There are no iron sights, but the 11mm dovetail on the receiver is ready for rings and the optic of your choice.
Why the 457 AT-ONE Action Stands Out
The 457 series brought some smart updates to CZ's rimfire lineup. The action is shorter and slab sided to trim weight and bulk, the bolt throw is a smooth 60 degrees for quick cycling and better scope clearance, and the receiver mounted push-to-fire safety works the way most American shooters expect. The trigger is fully adjustable for weight, creep, and overtravel, so you can tune it down to a crisp, clean break. Feeding comes from a reliable detachable 5 round polymer magazine, and the 457 platform keeps the swappable barrel system CZ fans know from the 455.
Whether you want a serious NRL22 base class rig, a squirrel rifle, or a trainer that grows with young marksmen, this one covers a lot of ground for a single rimfire.

Frequently Asked Questions
Is the CZ 457 AT-ONE Varmint barrel threaded for a suppressor?
Yes. The 16.5 inch heavy barrel comes threaded 1/2×28, which is the standard rimfire suppressor thread pitch in the US. The short, stiff barrel and quiet .22 LR chambering make this one of the more suppressor friendly setups in the 457 lineup.
Does the 457 AT-ONE come with a scope or iron sights?
No, it ships without sights. The receiver has an integral 11mm dovetail, so you will need 11mm rimfire rings or an adapter rail to mount an optic. Most owners pair it with a mid power scope for target work and small game.
How does the Boyds AT-ONE stock adjust?
Both adjustments work off simple push buttons, no tools needed. Length of pull moves from 12.5 to 14.25 inches and the comb rises up to 5/8 inch, so you can get proper eye alignment behind a scope. It makes the rifle easy to share between adults and younger family members.
Will the CZ 457 AT-ONE accept higher capacity magazines?
It ships with one 5 round polymer magazine, but the 457 uses the same proven magazine system as the CZ 455, so 10 round factory magazines are widely available. The 457 platform also supports CZ's swappable barrel system if you ever want to change calibers or barrel profiles.
