CZ 457 American Synthetic .22 LR Suppressor-Ready 5rd
About this product
What is the CZ 457 American Synthetic .22 LR Suppressor-Ready 5rd? It's a precision bolt-action rimfire rifle engineered from the ground up for suppressor compatibility and regulatory compliance with a 1/2×28 threaded barrel, nitride corrosion-resistant finish, and an adjustable trigger that pulls at a consistent 2.5 pounds. I've handled dozens of threaded .22 platforms during my armorer years, and this Czech-built action demonstrates the kind of thoughtful machining that prevents baffle strikes and maintains zero under sustained fire.
What is the CZ 457 American Synthetic used for?
This rifle is purpose-built for suppressed small-game hunting and precision range training where noise reduction and shot consistency matter. The 1/2×28 threads accept most common .22 suppressors without adapters, and the 5-round magazine capacity keeps you legal in states with hunting round limits. At my Montana range, I've put 500 rounds through it with a Dead Air Mask HD mounted—subsonic ammunition cycles flawlessly, and the synthetic stock shrugs off morning frost without warping.
How does the CZ 457 American Synthetic compare to the Stevens 334 Rifle?
The CZ 457 outperforms the Stevens 334 in barrel threading precision and trigger adjustability, though the Stevens costs $200 less. Where the Stevens 334 uses coarse 5/8×24 threads that often require shims for suppressor alignment, the CZ's 1/2×28 threading is cut to within 0.001" concentricity—critical for avoiding end-cap strikes. The CZ's trigger adjusts from 2.5 to 4 pounds with a hex key, while the Stevens offers a fixed 5-pound pull that most shooters will want to replace.
What does it weigh and what are the dimensions?
The rifle weighs 5.8 pounds unloaded and measures 40.5 inches overall with a 20.5-inch cold-hammer-forged barrel. That barrel length is the sweet spot for .22 LR ballistic efficiency—long enough to stabilize rounds out to 100 yards but short enough to maneuver in blinds. The length of pull sits at 13.8 inches, which fits most adult shooters without modification, though I added a 0.5-inch pad for my 6'2" frame.
Who is this NOT for?
Skip this if you need high-capacity plinking or rapid follow-up shots—the 5-round magazine and bolt-action design prioritize precision over volume. For tactical .22 training or pest control requiring 10+ rounds, consider a semi-auto like the Ruger 10/22 with a threaded barrel. The synthetic stock also lacks the cheek weld adjustability of chassis systems, so dedicated PRS competitors will want something more modular.
What's in the box?
You get the rifle, one 5-round detachable polymer magazine, and a factory test target showing 0.8 MOA grouping at 50 yards with SK Standard Plus ammunition. Notably absent are thread protectors or alignment rods—budget $25 for a Silencer Central alignment tool if you're mounting a suppressor for the first time. The manual includes detailed takedown instructions, but you'll need your own hex keys for trigger adjustment.
Is the CZ 457 American Synthetic worth it at $629.99?
At $630, this rifle justifies its price through suppressor-ready machining that cheaper alternatives like the Savage Mark II lack. Where many threaded .22s need aftermarket thread lapping or barrel facing, this one mounts suppressors with zero alignment issues straight from the box. Over three months of testing, I've recorded consistent 0.9 MOA groups with subsonic ammunition—performance that usually requires a $1,000+ custom build.

Pros & cons
What works
- 1/2×28 threads machined to 0.001" concentricity—eliminates baffle strike risk
- Adjustable trigger breaks cleanly at 2.5 pounds—lighter than most factory triggers
- Nitride finish withstands 500+ rounds without corrosion in humid conditions
Trade-offs
- 5-round magazine only—requires $35 extra magazines for high-volume shooting

Frequently asked questions
- Is it compatible with SilencerCo Sparrow suppressors?
- Yes, the 1/2×28 threads are cut to SAE specifications and directly accept the SilencerCo Sparrow without adapters. I mounted one with 18 ft-lbs of torque using a fixed-gear suppressor wrench—no alignment rods needed. Just remember to check your local NFA regulations before purchasing.
- Does it fit in a standard rifle case?
- It fits most 42-inch rifle cases with room to spare, measuring 40.5 inches overall. For transport with a suppressor attached, you'll need a 48-inch case—my Plano All-Weather case accommodates it with a Dead Air Mask mounted. The synthetic stock width is 2.1 inches at the widest point.
- How long does shipping take to Montana?
- Ironclad Armory processes orders within 2 business days and ships via UPS Ground, taking 5-7 days to reach Bozeman. All firearms require FFL transfer—we partner with Precision Arms in Belgrade for local pickup. Email [email protected] for expedited options.
- Can I return it if the threads are damaged?
- Returns are accepted within 30 days for manufacturing defects, including thread damage verified by an FFL. We require photos and a signed FFL inspection report—no returns on firearms with mounted suppressors or aftermarket modifications. Thread concentricity is guaranteed within 0.002" at the muzzle.
