The CZ 457 series thus offers exceptional user comfort due to its easy, fast and reliable operation, even with a riflescope attached. To ensure maximum safety, there is a positive safety on the right side of the receiver, a striker status indicator and a separate bolt extractor control. Shooting accuracy has also considerably improved with the use of a new adjustable trigger mechanism that features low trigger pull weight and excellent travel, combined with a noticeably lighter striker and a new type of bedding. A revolutionary innovation is the extremely durable anti-corrosion finish on metal parts that currently has no equal on the market. 

The CZ 457 series has retained all the important benefits of the previous CZ rimfire rifle generation: a modular system that allows for the easy replacement of barrels and change of calibers, as well as extremely reliable polymer magazines. 

With an artful design and perfect ergonomics, the 457 Thumbhole has a sturdy laminated stock with a unique integrated trigger guard and comes in a classy grey/brown color scheme. With symmetrical features, this modern thumbhole is equally comfortable for both right-handed and left-handed shooters. The stable nature of the laminated stock and varmint cold hammer forged barrel allow shooters to effectively engage medium and long-range targets. The Thumbhole is chambered in .22 LR and comes with a 20” barrel, with the option of chambering in the more powerful .17 HMR or .22 WMR. Its muzzle is threaded ½ x 20 UNF and comes equipped with an efficient cylindrical compensator. 

• Positive safety: The silent, positive safety allows natural and intuitive control of the firearm with a design that engages when pulled back to the shooter and released when pushed away from the shooter, thereby contributing to safe and comfortable handling. 
• Separate bolt removal control: The bolt can be extracted from the receiver without the need to pull the trigger. A separate and easily accessible control allows for the convenient and complete removal of the bolt for cleaning. 
• Open and remove bolt even with safety engaged: The bolt can be opened and removed even with the safety engaged, so you can safely check the condition of the firearm or unload it without having to release the safety. 
• Striker status indicator: The indicator features reliable detection of a cocked firing mechanism and can be checked both visually and by touch, which is advantageous when shooting in dim light or at night. 
• Adjustable trigger mechanism: The adjustable trigger mechanism allows you to precisely tailor the firearm to your needs. Trigger pull is preset to 12 N at the factory, but it can be easily adjusted from 8–15 N. Trigger travel can also be adjusted from 0.5–5 mm. 
• Lighter striker for increased speed and reduced vibration during firing: Striker weight has been reduced by 38% compared to the previous model, thereby preventing even the smallest vibration that could affect shooting accuracy. The striker is also modified for resistance to dry training. 
• New type of bedding for constant tightening of screws in stock: The bedding significantly contributes to long-term shooting accuracy and stability of attachment of the mechanism in the stock. It largely eliminates the effects of wood expansion under fluctuating temperatures, therefore remaining correctly sighted-in for longer periods of time and allowing you to shoot extremely accurately.
• 60° rotation of bolt handle: Bolt rotation has been shortened to 60°, which allows for convenient, smooth and quick reloading of the weapon, especially when optical sights are mounted. 
• New ergonomic stocks: The CZ 457 rimfire rifle series offers a wide range of stocks. The various options, shapes and materials have a strong emphasis on ergonomics, comfort and convenience of the shooter. You are sure to find one that fits you best. 
• Easy barrel replacement for quickly changing calibers: The improved modular system of the CZ 457 allows for the use of barrels in various calibers from the previous CZ 455 series, as well as barrel replacement with the use of CZ mini-sets. You can completely customize the firearm to your needs. 
• Cold hammer forged barrel: The most demanding, precise and expensive method of cold forging the barrel bore directs the flow of fibers, which positively affects the barrel's accuracy and service life. 
• MATCH chamber on selected models: Selected .22 LR caliber models, such as the CZ 457 MTR, have a MATCH chamber at the very edge of the CIP tolerance. Precision manufacturing and low tolerances provide an excellent accuracy of 1 MOA, depending on the ammunition used.
