Introduction
The CZ 512 is a semi-automatic rimfire rifle chambered in 22 Long Rifle caliber. Produced by Czech manufacturer Česká zbrojovka (CZ), it represents a modern evolution of small-caliber rifles designed for sport shooting, initiation and small hunting. Its architecture combines a gas borrowing system with a robust construction in light alloy and polymer. The CZ 512 is designed to offer a precise and reliable shooting platform in the 22 LR recreational rifle segment.
History and development
The development of the CZ 512 follows in the footsteps of the 22 LR semi-automatic rifles produced by Česká zbrojovka for several decades. The Czech manufacturer has long experience in the production of rimfire rifles, dating back to the days of Czechoslovakia.
The CZ 512 was introduced in the early 2010s as an evolution of previous models in the CZ 22 LR range. The project aims to modernize the manufacturer’s offering in the small-bore rifle segment by integrating features tailored to the contemporary expectations of sport shooters and small game hunters.
The design of the CZ 512 meets several objectives. The first is to offer a modular platform enabling different configurations to suit different uses. The second is to improve ergonomics compared with previous models, notably by adopting modern materials such as polymer for certain components. The third objective concerns ease of maintenance and reliability of feeding with different types of 22 LR ammunition.
CZ is developing the rifle with a gas-borrowing operating system, relatively unusual for a 22 LR weapon where the blowback system is more common. This technical choice is designed to reduce recoil and improve accuracy by limiting parasitic movements during firing.
Production of the CZ 512 begins at Česká zbrojovka in Uherský Brod, Czech Republic. The rifle is gradually distributed on the European and North American markets, where it meets with a favorable reception from shooters looking for a quality 22 LR rifle at a reasonable price.
In the years following its launch, CZ introduced several variants of the 512 to suit different user segments. Versions with synthetic stock, wooden stock, and different barrel lengths are offered to suit shooters’ preferences and local regulations.
Design and operation
The CZ 512 is a semi-automatic rifle operating on a gas-borrowing system. This mechanism, more complex than the free-breech system generally used on 22 LR rifles, enables smoother operation and better recoil management.
The operating principle is based on the recovery of part of the propellant gases generated during firing. These gases are extracted through an orifice in the barrel and directed to a piston which activates the locking and extraction mechanism. This system keeps the breech locked during the high-pressure phase, then opens it in a controlled manner for extraction and ejection of the case.
The barrel is made of steel and features a rifling pitch adapted to the 22 LR caliber. Barrel length varies from version to version, with standard models generally offering a barrel length of around 510 to 600 mm, depending on market and configuration. The barrel is screwed into the gas system housing and can be replaced for maintenance or configuration modification.
The gas recovery system housing and breech block are machined from aluminum alloy to reduce the overall weight of the weapon. The breech itself is made of treated steel to resist wear and tear caused by repeated opening and closing cycles.
The stock and guard are generally made of reinforced polymer on standard versions, offering good weather resistance and simplified maintenance. Versions with a wooden stock are also available for users who prefer traditional aesthetics. The stock is screw-fastened to the housing and can be removed for maintenance or transportation.
Feeding is via a removable polymer or steel magazine, depending on version. Standard capacity is 5 or 10 cartridges, depending on local regulations, although higher-capacity magazines may be available in some markets. The magazine is inserted into the well beneath the case, and is held in place by a locking system that can be released by means of a retaining button.
The trigger mechanism is of the single-action type. A manual safety catch is located on the side of the case and locks the trigger when engaged. Some versions feature an adjustable trigger mechanism, enabling the trigger travel and weight to be adjusted to the shooter’s preference.
The sights consist of a height-adjustable front sight and a notched rear sight adjustable for drift and elevation. These elements enable precise adjustment of the point of impact. The top of the housing is fitted with a Picatinny rail or equivalent mount for mounting a scope or other optics.
Disassembly for basic maintenance requires few tools. After checking that the weapon is unloaded and removing the magazine, the user removes the screws holding the stock together, separates the stock from the case, then gains access to the moving group and gas system for cleaning. The relative simplicity of disassembly facilitates the regular maintenance required with 22 LR ammunition, which generates significant combustion residues.

Their main interest
The CZ 512 is designed to meet the needs of sport shooters, recreational shooters and small game hunters looking for a reliable, accurate semi-automatic rifle in 22 LR caliber. The choice of a borrowed gas system rather than a free-floating bolt gives the rifle special operating characteristics.
The gas-borrowing system reduces felt recoil and limits vibrations transmitted to the stock when shooting. This feature improves shooting comfort, particularly during extended sessions, and makes it easier to maintain aim between successive shots. For shooters seeking precision on target, this reduction in parasitic movements is an appreciable advantage.
Reliable feeding with different types of 22 LR ammunition is an important point. The 22 LR caliber comes in many variants with different powder loads and velocities. The CZ 512 gas system is designed to work with a wide range of ammunition, although high-velocity ammunition is generally recommended for optimum performance.
The modularity of the platform allows users to adapt the rifle to their specific needs. The ability to mount different optics via the Picatinny rail, choose between different barrel lengths, and select the type of stock according to personal preference or regulatory constraints makes the CZ 512 versatile.
The low operating costs of the 22 LR caliber make the CZ 512 an economical platform for target practice. 22 LR ammunition is among the cheapest on the market, enabling high volumes of shooting on a limited budget. This feature is particularly appreciated for initiating new shooters and maintaining shooting skills.
Lightweight alloy construction helps reduce the rifle’s weight, making it easy to carry for extended periods on hunting outings or on the range. Despite this lightness, the structure retains sufficient rigidity to maintain good accuracy.
Main variants
Over the course of its production run, the CZ 512 has undergone a number of variants designed to meet the needs of different market segments and user preferences.
The standard version, often referred to as the CZ 512 Synthetic, features a black polymer stock and guard. This version favors practicality and weather resistance. The barrel generally measures around 510 mm, and the weapon is equipped with adjustable metal sights and an optics rail. This configuration is the basic model in the range.
The CZ 512 Carbine features a slightly shorter barrel, generally around 400 mm depending on the market, for a reduced overall length. This version favors maneuverability in tight spaces, and is particularly suited to young shooters or users looking for a compact rifle. The shorter barrel may slightly affect the velocity of the ammunition, but remains suitable for the typical shooting distances of the 22 LR.
The American version has features adapted to the North American market, with a more traditional-style stock and sometimes specific finishes. Some American versions feature a walnut stock to meet the aesthetic preferences of certain users.
Tactical versions are also produced, incorporating features such as a folding or telescopic stock, handguards with additional accessory rails for mounting vertical grips, tactical lights or laser pointers. These versions are aimed at the tactical leisure shooting and informal plinking segments.
The CZ 512 is sometimes offered with different surface treatments for the barrel and metal parts. Matt, black or camouflage finishes are available, depending on the version and production period.
Some versions feature threaded barrels for fitting sound moderators, which are legal in some countries to reduce detonation noise. This feature is particularly appreciated when shooting pests, or in environments where noise reduction is an advantage.
Comparison with other rifles
Compared with free-breech 22 LR rifles like the segment benchmark Ruger 10/22, the CZ 512 stands out for its gas-borrowing system. The Ruger 10/22 operates on a simple, robust free-breech principle that has proved its worth over many decades. The CZ 512’s system is mechanically more complex, but theoretically offers smoother operation with less felt recoil.
The Ruger 10/22 benefits from a highly developed ecosystem of accessories and spare parts, with hundreds of manufacturers offering upgrades and customizations. The more recent and less widely distributed CZ 512 has a smaller accessory market, although the essentials are still available.
Compared with the Marlin Model 60, a semi-automatic tubular rifle with a free-floating bolt, the CZ 512 offers the advantage of a detachable magazine for faster reloading. The Marlin is loaded via an under-barrel tube generally containing 14 to 18 cartridges, depending on the model, offering greater capacity but slower reloading. The CZ 512 prioritizes rapid magazine changes over raw capacity.
Compared to AR-15 family 22 LR rifles like the Smith & Wesson M&P 15-22, the CZ 512 features a more traditional architecture. The M&P 15-22 reproduces the ergonomics and controls of a military AR-15, enabling shooters to train on a familiar platform at lower cost. The CZ 512 adopts a more classic rifle shape, sometimes preferred for hunting or traditional leisure shooting.
Compared with bolt-action 22 LR rifles like the CZ 455 or Ruger American Rimfire, the CZ 512 offers a superior rate of fire thanks to its semi-automatic operation. Bolt-action rifles are generally recognized for offering slightly higher accuracy due to their stiffer mechanism, but require manual handling between shots. The choice between semi-automatic and bolt action depends on priorities between rate of fire and maximum accuracy.
Compared with pump-action rifles in 22 LR, which are relatively rare on today’s market, the CZ 512 eliminates the need for manual action between shots. Pump-action rifles may be of interest for training with higher-caliber pump-action long guns, but offer fewer practical advantages in the 22 LR segment.
Conclusion
The CZ 512 represents a modern approach to the semi-automatic rifle in 22 Long Rifle caliber. Its gas-borrowing system, unusual for this caliber, is designed to offer smoother operation and better recoil management than traditional free-breech systems.
Česká zbrojovka’s development of this rifle is a continuation of the Czech manufacturer’s expertise in small arms. The modularity of the platform and the availability of different variants mean that the CZ 512 can be adapted to a variety of uses, from sport shooting to small game hunting, via initiation and leisure.
The CZ 512’s position in the 22 LR rifle market remains that of a quality alternative to more widely available models such as the Ruger 10/22. Its unique technical system and meticulous construction appeal to shooters looking for a platform that differs from segment standards, while benefiting from the reputation for reliability associated with the CZ manufacturer.
