The CZ 457 AT-ONE cal. 22LR is a sporting precision shooting carbine equipped with a solid Boyds-branded stock with adjustable foot and cheekbone, a thick-walled cold-forged varmint barrel and a match-type cartridge chamber.
Varmint for precision shooting
The CZ 457 AT-ONE carbine used a heavy laminated stock from American manufacturer Boyds with a distinct pistol grip, an adjustable cheekbone and a quick-release QD belt clip. The buttstock has an adjustable LOP of 317-362 mm. The abbreviation LOP (Length of Pull) indicates the distance from the end of the flask to the face of the trigger tongue. Standard buckles allow the attachment of a stabilizing belt or bipod. The profile of the buttstock has been adapted for long-range shooting, making the carbine ideal for sport shooting in mini-sniper competition.
The carbine has a cold-forged, thick-walled barrel with a length of 525 mm, which guarantees excellent repeatability and precision shooting, as well as great durability. The barrel is terminated with a 1/2×20 UNF male thread for mounting the discharge devices.
Innovative solutions
The carbine features a firing pin tension indicator, which makes it easy to quickly check the status of the weapon. Another practical solution is a convenient breech removal system, without the need to press the trigger tongue, which significantly speeds up the partial disassembly of the weapon.
In the CZ 457, the user also has the possibility to remove the breech and unload the weapon on the activated safety.The CZ 457 family carbines use a new trigger mechanism, which allows adjustment of the trigger force from 8 to 15 N and the length of its path 0.5-7 mm. All metal parts of the CZ 457 have an extremely durable anti-corrosion finish. The manufacturer has also upgraded the design of the firing pin, its weight has been reduced by nearly 60%, which results in faster clanking and less shock after firing. Users will also appreciate the significantly reduced angle of rotation (by 30°) of the reloading lever, allowing comfortable use of scopes with a large eyepiece or low mount.
The carbine is fed from a removable magazine with a capacity of 5 cartridges. The carbine is deprived of mechanical sighting devices, but the user can mount optics of his choice on the picks of the cartridge chamber.
