CZ 457 Varmint .22LR 20" vs CZ 457 Royal .22LR 20.5": Bolt-Action Rimfire Comparison

Key Differences at a Glance

• Barrel profile & intent: The CZ 457 Varmint .22LR 20" uses a heavy/varmint-profile barrel aimed at steadier shot-to-shot behavior during longer strings, while the CZ 457 Royal .22LR 20.5" uses a light profile barrel oriented toward a lighter, more traditional sporter feel. (czub.cz)
• Overall weight: CZ 457 Varmint .22LR 20" is listed around 3.3 kg / 7.0 lb, while CZ 457 Royal .22LR 20.5" is listed around 6.2 lb in CZ-USA’s catalog. (czub.cz)
• Stock style & ergonomics: Both are described with an American-style comb intended for scoped shooting; the Royal variant emphasizes a longer, more decorative forend aesthetic and “classic rimfire” styling. (cz-usa.com)
• Muzzle threads:
  • CZ 457 Varmint .22LR 20": 1/2×28 thread listed in the 2025 CZ-USA catalog (common U.S. rimfire suppressor standard). (cz-usa.com)
  • CZ 457 Royal .22LR 20.5": 1/2×20 thread (noted by CZ-USA as a European standard). (cz-usa.com)
• MSRP (CZ-USA catalog): CZ 457 Varmint .22LR 20" listed at $649; CZ 457 Royal .22LR 20.5" listed at $799 (for the 20.5" Royal SKU). (cz-usa.com)

Current Market Position & Pricing

• MSRP reference point (not street price): CZ-USA’s 2025 catalog lists the CZ 457 Varmint .22LR 20" at $649 MSRP and the CZ 457 Royal .22LR 20.5" at $799 MSRP. That MSRP gap typically reflects the Royal’s styling/trim rather than a functional accuracy upgrade over the heavy-barrel Varmint. (cz-usa.com)
• Availability reality (U.S. market): Both models tend to appear in cycles; the 457 line commonly sells in runs and distributor allocations. The Varmint configuration is generally a higher-throughput “core” variant in the 457 family; the Royal is more niche and can be harder to find consistently in the same barrel length/thread pattern.
• Street pricing/stock levels: To keep within your source rules, I’m not citing retailer listings (and I’m avoiding marketplaces/aggregators). Practically, expect street price to vary significantly by region and shipment timing, and expect the Royal’s limited appeal to sometimes keep it closer to MSRP even when other 457 models discount.

Specifications Comparison

Important note on “20" vs 20.5" naming: CZ and importers sometimes describe the same 525 mm class barrel as 20" or 20.5" depending on market/catalog conventions. The CZUB listing shows the Varmint at 20" / 525 mm. (czub.cz)

Performance and Accuracy

• Mechanical accuracy potential: Both rifles use the CZ 457 action family and cold-hammer-forged barrels in the manufacturer’s materials for the line; the largest accuracy-relevant differentiator here is barrel profile (heavy vs light) and how that interacts with heat/handling during longer shot strings. CZUB lists the Varmint model with a heavy barrel and cold hammer forged barrel construction. (czub.cz)
• What the heavy barrel tends to change in practice (rimfire context):
  • Less point-of-impact shift as the barrel warms during longer strings.
  • More forgiving “hold” from bags/bipods due to mass.
  • Downside: the rifle is heavier to carry and slower to transition between targets.
• Ammunition sensitivity: With either model, .22 LR accuracy is dominated by lot-to-lot ammo variance and how a given chamber/barrel harmonizes with that ammo. The Varmint’s heavier tube may feel more consistent across long strings, but it won’t eliminate the need to test multiple match/standard-velocity loads.

Ergonomics and Handling

• Balance:
  • CZ 457 Varmint .22LR 20" will feel more front-heavy due to the heavy barrel. This is helpful from a bench or bipod and reduces wobble, but it’s noticeable offhand.
  • CZ 457 Royal .22LR 20.5" is lighter with a light-profile barrel, typically producing a more neutral feel for field carry and snap shots.
• Comb geometry: CZ-USA describes the Royal as intended for scoped use with a high, flat American-style comb; the Varmint is similarly positioned as a scope-oriented variant in the 457 family. (cz-usa.com)
• Controls: Both share the 457 family’s general manual of arms (60-degree bolt throw listed in CZ-USA tables for these models), and both are set up as optic-ready rifles (no irons). (cz-usa.com)

Features and Accessories

• Suppressor compatibility (threading is the key issue):
  • If you’re in the U.S. and already own rimfire suppressors and direct-thread mounts, 1/2×28 on the CZ 457 Varmint .22LR 20" is the more common match. (cz-usa.com)
  • The CZ 457 Royal .22LR 20.5" uses 1/2×20, which often requires a dedicated adapter or specific mount solution depending on your suppressor. CZ-USA explicitly notes this as a European standard. (cz-usa.com)
• Optics mounting: CZ 457 receivers are widely supported with 11mm dovetail rings and/or add-on rails (varies by user preference). The CZ-USA Royal description calls out the 11mm dovetail interface for mounting optics in the 457 family context. (cz-usa.com)
• Upgrade path (457 platform): The 457 system is known for modularity (barrel sets/stock swaps are common among owners). CZ-USA catalogs discuss the ability to swap chamberings with barrel sets within the 457 family. (cz-usa.com)

Real-World Applications

• Benchrest-style practice / groups / rimfire “trainer” role:
  • CZ 457 Varmint .22LR 20" generally fits better when you’re prioritizing stability from bags, longer strings, and a more “target” oriented feel.
• Small game / walking varminting / general field carry:
  • CZ 457 Royal .22LR 20.5" generally makes more sense when you want a lighter rifle that still accepts a scope and suppressor (with thread considerations).
• Suppressor-first setup:
  • If you want the simplest compatibility with common U.S. direct-thread rimfire cans, the Varmint’s 1/2×28 spec in the 2025 CZ-USA catalog is a practical advantage. (cz-usa.com)

Expert and User Reviews Analysis

• Professional review coverage: A dedicated review exists for the 457 Royal line noting availability in 16.5" and 20.5" .22 LR with 1:16 twist, aligning with the catalog specs. (shootingtimes.com)
• Common owner takeaways across CZ 457 variants (pattern-level, not model-exclusive): Owners frequently treat the 457 as a high-quality base rifle whose results improve with (1) careful ammo selection and (2) optics/rail setup appropriate to the distance discipline. This is consistent with how CZ-USA positions the 457 family for optic use and modularity. (cz-usa.com)

Final Verdict

• Choose the CZ 457 Varmint .22LR 20" if your priority is steady bench work, longer shot strings, and common U.S. suppressor threading (1/2×28), and you don’t mind the extra weight of a heavy barrel. (cz-usa.com)
• Choose the CZ 457 Royal .22LR 20.5" if you want a lighter, more traditional-styled scoped rimfire and you’re comfortable planning around 1/2×20 muzzle threads (either with the right adapter/mount or a dedicated setup). (cz-usa.com)
