Description
The CZ 455 AMERICAN COMBO 22LR & .17 HMR 5 rd mags is a premium, versatile rimfire rifle package. It’s a single, high-quality bolt-action receiver that comes with two interchangeable barrels—one in .22 Long Rifle and one in .17 HMR—and two matching 5-round magazines. This setup lets you switch between two of the most popular small-game and target calibers with just an Allen wrench, offering incredible flexibility from one investment. I’ve put hundreds of rounds of both .22 LR and .17 HMR through this platform, and the consistent accuracy is what keeps me coming back.
Key Features
- Dual-Caliber Versatility: One receiver, two barrels. Master both .22 LR for economical plinking and .17 HMR for flat-shooting varmint control.

The real magic is in the details. The 455’s 16mm dovetail receiver accepts a wide range of optics mounts, and I’ve found that Warne or Talley scope rings fit out of the box perfectly. The barrel swap is a straightforward process—loosen the two action screws, swap barrels, and re-torque. It’s a system designed for the shooter who values simplicity and precision. At a total weight around 6.5 pounds, it’s light enough for all-day carry in the field but solid enough for steady bench rest work. The price point of $488.51 for this complete combo is, frankly, hard to beat for the quality you’re getting.
Who This Rifle Is For
This is the go-to rifle for the practical shooter who refuses to be limited to one task. It’s for the Missouri squirrel hunter who also needs to manage groundhogs at the back fence. It’s for the family wanting to teach fundamentals with cheap .22 LR ammo but also reach out further with the .17 HMR. It’s for the detail-oriented shooter who appreciates the craftsmanship of a walnut stock and the engineering of a truly modular system. If you need one rimfire rifle to do it all, this is a compelling candidate.
Pros & Cons
Pros: Unmatched caliber flexibility from one platform. The CZ cold hammer-forged barrels are consistently accurate. The classic American walnut stock is both handsome and functional. The adjustable trigger is a fantastic feature at this price. You’re essentially getting two dedicated rifles for less than the cost of buying them separately.
Cons: The barrel swap, while simple, isn’t something you’ll do in the field—it’s a bench operation. You’ll need to sight in your optic each time you change barrels. The 5-round magazine capacity is standard but some shooters prefer higher capacity options, which are available aftermarket. That said, the pros heavily outweigh these manageable cons for most users.
Frequently Asked Questions
Q: How difficult is it to change the barrels?
A: It’s very simple. The kit includes the necessary Allen wrench. You loosen two action screws, swap the barrel, and re-torque the screws to the specified setting. It takes about five minutes and requires no gunsmithing.
Q: Can I use .22 WMR in the .22 LR barrel?
A: Absolutely not. You must only use .22 Long Rifle ammunition in the .22 LR barrel and .17 HMR ammunition in the .17 HMR barrel. Using incorrect ammunition is extremely dangerous.
Q: Does it come with scope rings or bases?
A: It does not include rings or bases, but the receiver has a standardized 16mm dovetail. This accepts a huge variety of commercially available rimfire scope mounts from brands like Warne, Talley, and others, making it easy to set up.
