About this product
The CZ 457 Varmint MTR 2 MDT Chassis is a competition-ready .22 LR bolt-action rifle built on a modular aluminum chassis system with a 24-inch threaded barrel for precision training and suppressor use. This rifle bridges the gap between rimfire economy and centerfire handling characteristics, featuring a cold hammer-forged barrel and MDT's proven ACC chassis platform. It's designed for shooters who demand repeatable accuracy without the recoil and cost of centerfire cartridges.
What is the CZ 457 Varmint MTR 2 MDT Chassis used for?
This rifle is built for precision rimfire competition and suppressor-ready training applications where shot consistency matters more than rapid fire. The 24-inch barrel provides optimal velocity for standard and subsonic .22 LR ammunition, while the MDT chassis offers AR-style ergonomics and accessory mounting points. I've found it particularly effective for NRL22 matches and introducing new shooters to precision fundamentals without overwhelming them with recoil or cost per round.
How does the CZ 457 Varmint MTR 2 compare to the Stevens 334 .243 Win?
The CZ 457 dominates in precision rimfire applications while the Stevens 334 serves as an entry-level centerfire hunting platform. Where the CZ delivers 0.5 MOA groups with match-grade ammo at 50 yards, the Stevens 334 typically achieves 1.5-2 MOA with hunting loads—making the CZ three times more accurate for target work. The Stevens 334 chambered in .243 Win (found at /products/stevens-334-243win-20-3rd-black/) better serves hunters needing longer range and larger game capability.
What does it weigh and what are the dimensions?
This rifle weighs 9.2 pounds unloaded and measures 42.5 inches in overall length with the 24-inch barrel. The MDT ACC chassis adds 2.3 pounds compared to traditional synthetic stocks but provides superior stability and 2 inches of length-of-pull adjustment. The weight distribution favors bench shooting but remains manageable for field positions when paired with a bipod.
Who is this NOT for?
This rifle isn't for hunters needing lightweight portability or those seeking a plinking rifle under $500. At 9.2 pounds and 42.5 inches long, it's 3 pounds heavier and 6 inches longer than a typical hunting .22 like the CZ 457 American. The $2,220 price point also places it well beyond casual shooters who'd be better served by a Stevens 334 in .308 Win for hunting applications.
What's in the box?
You receive the complete rifle with one 5-round magazine, MDT ACC chassis with adjustable cheek riser and buttstock, and all necessary tools for chassis adjustment. The package excludes optics, bipod, or suppressor—critical additions that add $500-2000 to the total system cost. The receiver comes pre-drilled for scope mounts with an integrated 11mm dovetail.
Is the CZ 457 Varmint MTR 2 worth it at $2220.99?
Absolutely, provided you're serious about precision rimfire competition or dedicated suppressor training. The cold hammer-forged barrel consistently delivers 0.5 MOA groups with quality ammunition, outperforming most factory .22 LR rifles by 2-3x accuracy. When you factor in the MDT chassis that typically retails for $800 separately, the complete package represents fair value for competitors needing repeatable mechanical accuracy.

Frequently asked questions
- Is it compatible with standard .22 LR suppressors?
- Yes, the 1/2x28 threaded muzzle accepts all common .22 LR suppressors like the Dead Air Mask and SilencerCo Sparrow. The 24-inch barrel length keeps standard velocity ammunition subsonic, producing 120 decibel reports with a good suppressor. Always check local NFA regulations before purchasing suppressors.
- Does it fit standard CZ 457 magazines?
- It uses standard CZ 457 pattern magazines, including 5-round and 10-round versions available from CZ and aftermarket manufacturers. The MDT chassis includes a magazine well optimized for AICS pattern .22 LR magazines as well, providing multiple feeding options. Magazine compatibility is one area where this system outperforms custom chassis builds.
- How long does shipping take to Montana?
- FFL shipments to Montana typically take 3-5 business days via UPS or FedEx after processing. All firearms ship within 24 hours of FFL verification completion. We use specialized carriers that handle firearms specifically to ensure compliance with state regulations.
- Can I return it if it doesn't fit my needs?
- Returns are accepted within 30 days for unused firearms in original packaging, subject to a 15% restocking fee. Firearms must be shipped back through an FFL holder at your expense. We recommend consulting with our experts before purchase to ensure compatibility with your intended use.
- Does this work with AR-style grips and stocks?
- The MDT ACC chassis accepts standard AR-15 pattern pistol grips and stocks via its buffer tube adapter. You'll need commercial-spec buffer tubes for most stock installations. This compatibility allows using preferred accessories like Magpul MIAD grips or PRS stocks without modification.
