CZ 457 history & timeline

Česká zbrojovka's Uherský Brod factory established.

Brno Model 2 (also known as the ZKM 452) — the ancestor of the 452/455/457 line (following the Model 1 of 1945).

The 452 becomes the basis for CZ rimfires offered on the US market once Czech imports resume.

CZ-USA founded (1997) as the US distribution/service subsidiary; moves to Kansas City, Kansas in 1998. Variants such as the American added; .17 HMR and .17 Mach 2 chamberings introduced over the 452 era. The 453 was a 452 with a better (incl. single-set) trigger.

CZ 455 introduced: barrel retained by two coned set screws for quick caliber swaps (vs threaded/pinned 452 barrels) — the interchangeable-barrel system the 457 keeps. Some owners criticised it as cost-driven (e.g., magnum-size bolt for all calibers).

CZ 457 replaces the 455: action ~1 in shorter and slab-sided, 60° bolt lift (was 90°), US-style push-forward-to-fire safety (requested by Hunter Ed and 4-H instructors), new adjustable trigger, cocking indicator, bolt removable with safety on, ~2/3 lighter striker, improved bedding, nitride anti-corrosion finish. Barrels and mags remain 455-compatible.

Launch line-up (US) included Varmint, Varmint MTR, Varmint Precision Trainer, Pro Varmint SR, Varmint AT-ONE, Lux, Training Rifle, American and Scout; e.g., American from $476, Varmint MTR $752 MSRP.

Three threaded models added (Synthetic, Thumbhole, Long Range Precision).

CZG (Česká zbrojovka Group) completes the acquisition of Colt; the group later renames itself Colt CZ Group.

At the first IPRF PR22 World Championship (Italy, 179 shooters), the CZ 457 was the most common rifle/action in the (anonymous) equipment survey.

CZ 457 Target (12-groove 26 in barrel, 12 mm guarantee) and the two-stage Flyweight trigger (standard on Target, fits all 457s) appear in CZ documentation.

CZ US lists 457s from $649 (Scout) to $2,399 (Manners/Precision Chassis MTR).
