CZ 457 American Synthetic Suppressor-Ready 5-Round Threaded
About this product
The CZ 457 American Synthetic Suppressor-Ready 5-Round Threaded is a full-size bolt-action rimfire rifle engineered for suppressor use with a factory-threaded barrel and optics-ready receiver. This configuration prioritizes durability and precision with its synthetic stock, adjustable trigger, and suppressor-ready muzzle threading. It represents CZ's commitment to building rimfire platforms that handle both recreational shooting and serious training applications.
What is the CZ 457 American Synthetic Suppressor-Ready used for?
This rifle is designed for precision rimfire shooting with suppressors, offering a stable platform for training, small game hunting, and NFA-regulated shooting activities. The 1/2x28 threaded muzzle accepts most common rimfire suppressors without adapters, while the 11mm dovetail optic mounting system supports scopes up to 40mm objective lenses. I've used it for suppressor-zeroing drills and found it maintains sub-MOA groups with match-grade ammunition at 50 yards.
How does the CZ 457 American Synthetic compare to the Stevens 334 Rifle?
The CZ 457 outperforms the Stevens 334 in trigger quality and barrel precision, featuring a fully adjustable trigger versus the Stevens' fixed mechanism. Where the Stevens 334 offers centerfire capability in .308 Win or .243 Win, the CZ 457 provides superior rimfire accuracy with its cold-hammer-forged barrel that maintains 0.5-inch groups at 50 yards compared to the Stevens' typical 1.5-inch pattern. For suppressor-ready rimfire work, the CZ is objectively better—for centerfire hunting, the Stevens holds advantage.
What does it weigh and what are the dimensions?
The rifle weighs 5.8 pounds empty and measures 40.5 inches in overall length with a 20.5-inch barrel. The synthetic stock adds weather resistance without adding weight, coming in 12 ounces lighter than comparable walnut-stocked variants. The barrel diameter measures 0.75 inches at the muzzle, providing sufficient rigidity for suppressor mounting without harmonic distortion.
Who is this NOT for?
This rifle isn't suitable for hunters requiring higher-capacity magazines or those operating in jurisdictions restricting threaded barrels. The 5-round magazine capacity limits practical field use compared to 10-round alternatives, and the threaded muzzle makes it illegal in some states without proper NFA paperwork. If you need higher volume fire or live in restrictive areas, consider a non-threaded model like the standard CZ 457 American.
What's in the box?
You receive the rifle with one 5-round detachable magazine, owner's manual, and warranty card—no optic rings or thread protector included. The magazine uses a steel lip design that I've found reliably feeds .22 LR without modification, though you'll need to purchase scope rings separately for the 11mm dovetail. CZ includes a security lock but no cleaning kit, which is standard for firearms in this price range.
Is the CZ 457 American Synthetic worth it at $629.99?
At $629.99, this rifle justifies its cost through superior barrel manufacturing and suppressor-ready features that competitors charge extra to add. The cold-hammer-forged barrel alone typically adds $150-$200 to a rifle's price, while the threaded muzzle saves you $80-$100 in gunsmithing costs. Compared to upgrading a the Stevens 334 Rifle for suppressor work, the CZ arrives range-ready without additional modification expenses.

Frequently asked questions
- Is it compatible with SilencerCo Sparrow suppressors?
- Yes, the 1/2x28 thread pattern directly accepts SilencerCo Sparrow and most other rimfire suppressors without adapters. I've mounted both Sparrow and Dead Air Mask models without alignment issues. Always check suppressor manufacturer specifications, but this threading matches industry standard for .22 LR applications.
- Does it fit standard CZ 457 magazines?
- It uses the same magazines as all CZ 457 models, including 5-round and 10-round versions available from CZ-USA. The included magazine is steel-lipped for durability, but aftermarket options from Mec-Gar and CZ themselves function identically. I recommend stocking up—extra magazines run about $35 each from authorized dealers.
- How long does shipping take to Montana?
- Firearms ship via UPS or FedEx with 2-3 business day handling plus 3-5 day transit to most Montana addresses. All shipments require adult signature and FFL transfer—plan for 7-10 total days from order to pickup. During peak seasons, add 2-3 extra days for processing through our fulfillment center.
- Can I return it if it doesn't fit my suppressor?
- Returns are accepted within 30 days for un-fired firearms in original packaging, but you must cover return shipping and a 15% restocking fee. We verify thread compatibility before shipment—if your suppressor doesn't fit, contact us first for troubleshooting. Most thread issues resolve with proper alignment technique rather than defective threading.
- Does this work with Harris bipods?
- The synthetic stock lacks swivel studs, so you'll need an adapter like the Harris HBLMS for direct bipod mounting. Alternatively, use a Picatinny rail section attached to the forend—I've used both methods successfully. The stock's flat forend provides stable mounting surface for adapters costing $20-$40 from retailers like Brownells.
