CZ 452


CZ 452 with a fitted suppressor

The CZ 452 / BRNO Model 2 (ZKM 452). is a series of magazine-fed bolt-action rimfire repeating rifles manufactured by the Czech firearms manufacturer Česká Zbrojovka Uherský Brod (abbreviated "CZ-UB", English: Czech Weapons Factory — Uherský Brod) and imported into the United States by CZ-USA. Most versions of the 452 rifle series were discontinued in 2011 and replaced by the CZ 455, although CZ continues to offer the CZ 452 American in a left-hand model, with the bolt handle and ejection port located on the left side of the rifle.

During its production life, the CZ 452 was produced in several versions with various barrels, stocks and sights for a variety of rimfire cartridges such as .22 LR, .22 WMR, .17 HM2, and .17 HMR.

History
First introduced in 1954 as the BRNO Model 2 (ZKM 452), the Model 452 is a refinement of the CZ Model 1 (ZKM-451) .22 calibre rimfire bolt-action training rifle that first appeared in 1947. ZKM is an acronym for Zbrojovka-Koucký-Malorážka, the rifle`s manufacturer ([Česká] Zbrojovka), designer (Josef Koucký) and Malorážka - for rimfire rifle). The Model 1 or ZKM-451 was developed on the request of the occupying German authority in 1943-44, when a very few rifles were built as fully stocked Mauser 98k type trainers. The receivers of these early .22 training rifles were marked tgf (Tschechische Gewehr Fabrik - German for Czech Rifle Factory) by the German Heereswaffenamt. Because of wartime requirements for combat weapons, assembly and production was halted on all .22 training rifles, leaving a large stockpile of parts and receivers at war`s end. After the war, these parts (some of which still have the tgf code) were used along with new barrels and stocks to make the Model 1.

Common Features
The CZ 452 features a carbon steel barrel that is threaded into the receiver frame, except for rifles chambered for .17 HM2 which have the barrel pinned to the receiver.

Rifles of recent manufacture feature hammer forged and lapped barrels.

The receiver has a dovetail rail for mounting a telescopic sight. The dovetail is either 11 mm or 3/8" depending on the version and cartridge.

The trigger mechanism is adjustable for weight of pull.

A detachable box magazine is used for feeding. Magazines are available in 5- and 10-round capacities for all cartridges. A single-shot adapter and 25-round magazine are also available for use with .22 LR and .17 HM2.

Versions

- American
The American is equipped with a 22.5" (572 mm) sporter weight barrel. The barrel and receiver have a polished and blued finish. They sit in an American-style, straight-comb, Turkish walnut stock with checkered grip and fore-end, and is trimmed with sling studs and a hard plastic butt plate. It was offered in limited quantities with beech, maple, and fancy walnut stocks. There is no provision for iron sights, as it is designed for use with a telescopic sight. The American was chambered for .17 HM2, .17 HMR, .22 LR, and .22 WMR in right-handed rifles, and for .17 HMR and .22 LR in left-handed rifles. Currently, the left-handed version is still in production.

Versions were offered with either a 16.2" or 22.5" inch barrel with the muzzle threaded (1/2" x 20 threads per inch (TPI)) to accept a sound suppressor. Adapters to allow attachment of U.S. standard (1/2" x 28 TPI) suppressors are available from several manufacturers.

- Varmint
The Varmint is equipped with a 20.5" (521 mm) straight tapered varmint/target barrel. The barrel is polished whereas the receiver has a matte finish; both are blued. The barreled action sits in a varmint-style, straight-comb, walnut stock having a checkered grip with a modest palm swell and a flat-bottomed fore-end, and is trimmed with sling studs and a rubber butt pad. There is no provision for iron sights, as it is designed for use with a telescopic sight. The Varmint was chambered for .17 HM2, .17 HMR, .22 LR, and .22 WMR.

- Lux and Trainer

The Lux is equipped with a 24.8" (630 mm) barrel that is provisioned with tangent sights. The barrel is polished whereas the receiver has a matte finish; both are blued. The barreled action sits in a walnut stock in the European-style with checkered grip, schnabel fore-end, and arched (curved) comb sometimes referred to as a Bavarian or "hogback" stock, and is trimmed with European sling swivels and a hard plastic butt plate. The lower drop at the heel and arched comb of the stock are designed to aid shooting with iron sights. The rear tangent sight is graduated in 25 meter increments with calibrated markings from 25 to 200 meters, while the sight leaf is adjustable for windage. The hooded front sight blade is adjustable for elevation. The Lux was chambered for .22 LR and .22 WMR. A left-handed version was chambered for .22 LR.

The Trainer, also knows as the Special or Special Military Training Rifle, is identical to the Lux except it is provided with a beechwood stock that is otherwise identical. The Trainer was chambered for .22 LR and .17 HMR.

- Ultra Lux
The Ultra Lux is equipped with a 28.6" (727 mm) barrel that is provisioned with tangent sights. The extra length of the barrel is intended to improve sight radius and thus accuracy when using open sights. The barrel is polished whereas the receiver has a matte finish; both are blued. The top of the barrel is marked "SUPER EXCLUSIVE" and the trigger is gold plated. The barreled action sits in a European beechwood stock with a checkered grip, a Bavarian-style comb that also features a cheek piece, and is trimmed with European sling swivels and a rubber butt pad. Unlike the Lux and Trainer, the tangent sight is calibrated from 25 to 100 meters in 25 meter increments, and then extends to 300 meters in 50 meter increments. The rear sight leaf is adjustable for windage, while the hooded front sight blade is adjustable for elevation. The Ultra Lux was provided with a 10-round magazine, and chambered for .22 LR.

- Scout
The Scout is a compact rifle intended for young shooters, with reduced stock dimensions, reduced weight, and a single-round loading device. The reduced stock dimensions and weight also make it suitable for smaller adults. The single-round loading device helps teach ammunition conservation and marksmanship. It has a shortened beechwood stock with a straight, slightly dropped comb, and a blued metal finish. It also uses notch and post sights.

- Silhouette and Style
The Silhouette was designed for small-bore metallic silhouette shooting competitions, and to meet the requirements of the IMSSA. It is essentially a CZ American action and barrel in a synthetic stock with a raised comb and cheek piece. Blued metal finish.

A version was offered with a 16.2" inch barrel with the muzzle threaded (1/2" x 20 threads per inch (TPI)) to accept a sound suppressor.

The Style is identical to the Silhouette except that it features a matte nickel electroplate finish on all metal surfaces except for the bolt and trigger assemblies.

- FS (Full Stock)
The FS, short for Full Stock, features a carbine length (20.7") barrel and a Mannlicher–Schönauer-style full-length Turkish walnut stock with checkering on the pistol grip and forearm. The FS features the same tangent sights as the Lux and Trainer. The dovetail rail on the receiver accepts either 11 mm (for 22 LR versions) or 3/8" (for 17 HMR and 22 WMR versions) scope rings.

- Grand Finale
Released in 2017, the Grand Finale is a limited run of 1,000 rifles to commemorate the CZ 452 line. It follows the pattern of the CZ 452 American, but features an oil-finished walnut stock with ebony fore-end tip and grip cap, is hand engraved with a high polish blued finish, has a gold plated trigger, and features a custom metal magazine floor plate. It is provided with matching engraved and high polish blued scope rings.

Variants

- CZ 453
The CZ 453 is essentially the same as the CZ 452; however, it is equipped with a fully adjustable single-set trigger. Some components, such as a different trigger housing and unique action screws, differ from the CZ 452 to accommodate the single set trigger, and thus the CZ 453 trigger cannot be retrofit into a CZ 452. Three versions were produced: American, Varmint, and Lux. The American and Varmint are essentially the same as the respective CZ 452 version. The Lux is akin to the CZ 452 version, but features the modern stock of the CZ 527 Lux, which features panel checkering on the grip and fore-end, a cheek piece, and a rubber butt pad. The Lux was only offered in 22 LR.

- CZ 513
The CZ 513 Basic (or Farmer as it is known outside the USA) is an economy version of the CZ 452, and with a 20.9-inch barrel and an uncheckered beechwood stock. The trigger is not adjustable, and the rear sight is a simple notch and post type.
