Description
You’re at the range, trying to zero in your rimfire for a prairie dog town trip. The ammo is good, the day is calm, but you just can’t get that perfect, repeatable cheek weld. Your groups are okay, but not the tack-driving consistency you know is possible. That’s the exact frustration the CZ 457 At-One Varmint 17 HMR 20″ Barrel, Wood, Blued, Adjustable Comb, 5rd is engineered to solve. It’s a rifle built not just to shoot, but to fit you, delivering precision without a custom shop price tag.
The CZ 457 At-One Varmint is a purpose-built, adjustable-chassis rimfire rifle chambered in the flat-shooting .17 HMR cartridge. It features a 20-inch cold hammer-forged barrel for inherent accuracy, a user-adjustable Boyd’s At-One stock for a perfect custom fit, and CZ’s renowned 457 action known for reliability. Priced at $645.86, it offers a serious upgrade in ergonomics and long-range capability over standard sporter rifles, making it a standout value for the dedicated small-game hunter or target shooter.
Let’s break down where your money goes. The heart is CZ’s 457 action, a benchmark for smooth operation and crisp trigger performance right from the factory. It’s paired with a 20-inch heavy, sporter-contour barrel. That length is a sweet spot for the .17 HMR, allowing the hyper-velocity round to reach its potential without being unwieldy. The blued finish is classic and durable, a practical choice that keeps the cost sensible. The real game-changer, though, is sitting out back.
The Boyd’s At-One stock is what separates this from other varmint rifles. You get a fully adjustable comb height and length of pull—no gunsmithing required. A few turns of an Allen key lets you dial in the perfect cheek weld and reach for your body and optics. This isn’t a flimsy add-on; it’s a solid, laminated hardwood stock with an integrated recoil pad and multiple sling stud options. The result? Consistent eye alignment shot after shot, which is the secret to tiny groups at 150+ yards. The rifle ships with a single 5-round detachable magazine, a reliable and flush-fitting design.
Here’s the thing—comparing it to a basic synthetic-stock .17 HMR, the value proposition becomes clear. You’re paying a premium for the adjustability, but you’re getting a feature typically found on rifles costing hundreds more. It’s a buy-once, cry-once scenario. The rifle weighs in around 7.5 pounds, giving it a steady feel off the bench or bipod without being a burden in the field. It’s compatible with a wide array of aftermarket accessories, including popular scope rings and bases designed for the CZ 457 dovetail, like those from Warne or DIP.

Pros: The adjustable stock is a massive benefit for precision shooting and can be shared among shooters of different sizes. CZ’s out-of-the-box accuracy is legendary. The .17 HMR chambering offers laser-like trajectory and explosive terminal performance on varmints. The fit and finish are excellent for the price point.
Cons: It’s heavier than a sporter rifle, so it’s less ideal for long walks. The .17 HMR ammo is more expensive than .22 LR. The laminated wood, while tough, isn’t as weather-forgiving as a synthetic stock. You’re investing in a specialized tool.
So who is this rifle for? It’s perfect for the Missouri hunter who spends weekends at the farm clearing ground squirrels or predators with a focus on first-round hits at extended ranges. It’s also a fantastic entry point for a new shooter interested in precision rimfire competition, as the adjustable stock teaches proper fundamentals. If you need a lightweight, all-weather brush gun, look elsewhere. But if you want a versatile, accurate platform you can tailor to your body—a rifle that grows with your skill—this is a compelling choice.

Frequently Asked Questions
Q: Can the stock adjustments be locked in place securely?
A: Absolutely. The comb height and length of pull adjustments use solid, threaded mechanisms that lock down tightly with an Allen key. Once set, there’s no wobble or shift, ensuring a consistent fit for repeatable accuracy.
Q: Is this rifle a good candidate for a suppressor?
A: Yes, it’s an excellent host. The 20-inch barrel has a 1/2″-28 threaded muzzle (under a protective cap), which is the standard thread pitch for many .17 caliber rimfire suppressors from brands like SilencerCo or Dead Air. Always check local regulations regarding suppressor use.
Q: How does the .17 HMR compare to .22 WMR for varmint hunting?
A: The .17 HMR has a much flatter trajectory and higher velocity, making windage and holdover calculations easier at longer ranges (150-200 yards). The .22 WMR hits with more blunt force at closer ranges. For pure long-range precision on small varmints, the .17 HMR in a stable platform like the At-One is hard to beat.
