Description
There's a reason the CZ 457 American keeps showing up in conversations about the best rimfire rifles money can buy. CZ took everything people loved about the old 455 and tightened it up. The action lost nearly an inch of length, picked up slab-sided cuts to trim weight, and traded the stamped bottom metal for a cleaner two-piece setup. The result is a trim, well-balanced bolt gun that feels like it was built by people who care about the details, because it was.
A .17 HMR That Earns Its Keep
This version is chambered in .17 HMR, and it's a natural fit for the platform. The 24.8 inch cold hammer forged barrel with a 1:9 twist gives that speedy little cartridge room to stretch its legs, and owners routinely report tight groups out to 100 yards and beyond. Prairie dogs, ground squirrels, and steel targets at distances that make a .22 LR sweat, this is the tool for that work. The five-round detachable polymer magazine feeds smoothly and drops free without fuss.
Built Around Your Optic
There are no iron sights here, and that's by design. An 11mm dovetail is milled straight into the receiver, so you can mount rings and get a scope on it without buying a separate base. CZ also went with a 60 degree bolt rotation instead of the usual 90, which keeps your hand clear of larger ocular bells and lets you run lower ring heights. The trigger is adjustable for weight, creep, and overtravel, so you can dial it in exactly how you like it.
Traditional Looks, Modern Manners
The Turkish walnut stock wears an American-style profile with a high, flat comb that lines your eye up naturally behind a scope, plus classic checkering at the grip and forend. The receiver-mounted push-to-fire safety works the way most American hunters grew up expecting, which was a long-requested change CZ finally delivered on this platform. Add in the 457 family's swappable barrel system and you've got a rifle that can grow with you for years. At around 6.2 pounds, it carries easily in the field and settles nicely on the bench.

Frequently Asked Questions
Does the CZ 457 American come with iron sights?
No, this model ships without sights and is designed to be run with a scope. The receiver has an 11mm dovetail milled directly into the top, so you just need a set of 11mm rings or a dovetail-to-Picatinny adapter to mount your optic. The high, flat comb on the walnut stock is shaped to give you proper eye alignment behind a scope.
How accurate is the CZ 457 American in .17 HMR?
This is one of the more accurate factory rimfire rifles on the market. The cold hammer forged 24.8 inch barrel and crisp adjustable trigger do a lot of the work, and owners commonly report groups in the neighborhood of a half inch at 100 yards with ammo the rifle likes. As with any rimfire, it pays to test a few brands and bullet weights to find what your particular barrel prefers.
Can I adjust the trigger on the 457 American?
Yes, the 457 trigger is adjustable for pull weight, creep, and overtravel right from the factory. That was one of the bigger upgrades CZ made when moving from the 455 to the 457 platform. Most folks find they can tune it down to a clean, light break that suits precision work.
Does the 457 American use the swappable barrel system?
It does. The 457 shares the same interchangeable barrel and stock system as the older 455, along with the same reliable polymer magazine design. That means you can swap in barrels in other rimfire chamberings down the road, making this one rifle that can wear a lot of different hats.
