The CZ 457 is a bolt-action .22 LR rifle with a 20-inch threaded barrel and a Cerakote finish. At 5.4 lbs. it's light enough to carry comfortably for long sessions, and the .22 LR chambering keeps ammunition costs low for high-volume target practice or small game work.

Features 

 
The bolt cycles smoothly and the action is well-fitted for a rimfire rifle. The threaded muzzle accepts suppressors and muzzle devices, a useful option for .22 LR where suppressor use is relatively quiet and common. The 11mm dovetail is the standard CZ scope mount interface; rings and mounts are widely available. 
 
The Cerakote finish on the synthetic-stocked package handles weather reasonably well. The trigger is adjustable. CZ's 457 platform is modular, so barrels and stocks from other 457 variants swap in.

Owners of the CZ 457 in .22 LR generally have positive things to say about accuracy and construction. The bolt action is frequently described as one of the smoother rimfire actions available, and the rifle tends to group well with quality ammunition. Build quality draws consistent praise. It's noticeably better fitted than most rimfire rifles in the same price range.

The threaded barrel gets positive mentions from users who run suppressors. The adjustable trigger is appreciated for allowing a cleaner pull than factory. The 457 platform's modularity (swap barrels and stocks) is a selling point for users who want one action with multiple configurations.

Common criticisms: the base magazine capacity of 5 rounds is low compared to some competitors, and the price sits higher than many .22 bolt rifles. Users who compare it to cheaper .22s typically find the premium justified, but buyers on a tight budget note the cost. Scope mount compatibility is sometimes flagged. The 11mm dovetail is fine, but some users prefer Picatinny from the factory.
