5 Best .22 CO₂ Air Rifle 

The Diana Trailscout CO₂ Air Rifle is a .22-caliber bolt-action air rifle designed for target shooting, plinking, and recreational shooting. It combines a multi-cartridge CO₂ system with a rifled barrel, adjustable trigger, repeater capability, and an 11mm dovetail rail for mounting an optic. With a maximum velocity of 560 FPS and up to 11.5 FPE of energy, it offers a practical balance of shooting performance and convenience.

Key Features

Three-Cartridge CO₂ System

One of the most distinctive features of the Diana Trailscout is its patented three-cartridge carriage system. The rifle uses three 12-gram CO₂ cartridges, providing approximately 100 shots per fill under stated conditions. This gives shooters substantially more shots between cartridge changes compared with many CO₂ air rifles that use a single cartridge.

The cartridges are not included with the rifle, so users need to purchase them separately. CO₂ performance can also vary depending on temperature, shooting pace, and cartridge condition.

Bolt-Action Repeater

The Trailscout uses a bolt-action system and can operate as a repeater with its included magazine. The supplied .22-caliber magazine holds multiple pellets, allowing the shooter to fire successive shots without manually loading a pellet into the single-shot tray after every shot.

For shooters who prefer more deliberate shooting, the rifle also includes a single-shot tray. This gives users the option of loading pellets individually when they want to concentrate on careful target shooting.

.22-Caliber Performance

The Trailscout is chambered in .22 caliber and has a listed maximum velocity of up to 560 FPS. Its maximum energy is rated at 11.5 foot-pounds, making it suitable for recreational shooting and target practice.

The .22-caliber pellet is larger and heavier than a typical .177-caliber pellet, providing a different shooting experience for users who prefer the .22 platform.

19-Inch Rifled Barrel

The rifle features a 19-inch rifled barrel. Rifling imparts spin to the pellet as it travels through the barrel, which is an important part of the rifle’s design for controlled and consistent pellet flight.

The relatively long barrel also contributes to the Trailscout’s traditional rifle profile while keeping the overall length at 38.9 inches.

Adjustable Trigger

The Diana Trailscout features an adjustable trigger, allowing shooters to modify the trigger characteristics to better suit their preferences. A predictable trigger can be useful during deliberate target shooting because it allows the shooter to concentrate on sight alignment and shot placement.

Sighting System

The rifle comes with a fixed blade front sight and adjustable rear notch sight. This provides a conventional open-sight setup for users who prefer shooting without an optic.

For shooters who want magnification or another aiming system, the Trailscout has an 11mm dovetail optics rail. This allows a compatible optic to be mounted to the rifle.

Ergonomic Stock Design

The Trailscout features a checkered pistol grip and forearm, which can provide additional grip and control when handling the rifle. The checkering also gives the rifle a traditional sporting appearance.

Lightweight Construction

At approximately 5 pounds, the Diana Trailscout is relatively light for a full-length air rifle. Its 38.9-inch overall length provides a conventional rifle profile while maintaining a manageable weight for recreational shooting.

Shooting Performance

With a listed maximum velocity of 560 FPS and maximum energy of 11.5 FPE, the Diana Trailscout is designed more around practical recreational shooting and target practice than extreme power. The combination of a .22-caliber pellet, rifled barrel, adjustable trigger, and open sights gives it a setup suitable for shooters who want a straightforward CO₂-powered rifle.

The three-cartridge system is particularly useful for extended shooting sessions. With approximately 100 shots per fill under the manufacturer’s stated conditions, users can spend more time shooting before replacing the CO₂ cartridges.

Magazine and Single-Shot Options

The Trailscout provides flexibility by supporting both magazine-fed and single-shot operation. The rifle includes one magazine as well as a single-shot tray. The supplied information describes the .22-caliber magazine as a 7-shot magazine, while the product description also references a 9-shot magazine. Because these specifications conflict, buyers should verify the magazine capacity of the exact .22-caliber model before purchasing.

The Beeman Rebel QB78-22 is a .22-caliber CO₂-powered bolt-action air rifle designed for recreational shooting, target practice, and outdoor use. It combines a traditional hardwood stock with a blued finish, adjustable trigger, manual safety, and a two-cartridge CO₂ system. With a listed velocity of up to 500 FPS, the rifle emphasizes straightforward handling and a classic sporting-rifle design rather than high-powered performance.

Key Features

CO₂-Powered Operation

The Beeman Rebel QB78-22 operates using two standard 12-gram CO₂ cartridges. The cartridges provide the rifle’s power source and eliminate the need for a spring-piston or gas-ram mechanism. The two-cartridge system is particularly convenient for recreational shooting because it allows the rifle to be used without manually cocking a spring before each shot.

CO₂ performance can vary depending on temperature, shooting pace, and cartridge condition, so actual performance may differ from the manufacturer’s listed figures.

.22-Caliber Bolt Action

The rifle is chambered in .22 caliber and uses a bolt-action design. The supplied specifications describe the .22 version as a CO₂ bolt-action single-shot rifle. This configuration makes it appropriate for shooters who prefer a deliberate loading and shooting process rather than a rapid-fire repeating mechanism.

The bolt-action design also contributes to the traditional sporting-rifle feel of the QB78-22.

Hardwood Stock

The Beeman Rebel features a European hardwood stock, giving it a classic appearance and traditional rifle feel. The hardwood construction provides a more conventional sporting-rifle aesthetic compared with synthetic-stock CO₂ air rifles.

The stock is complemented by the rifle’s blued finish, creating an understated appearance suitable for users who prefer traditional airgun styling.

Blued Finish

The rifle has a blued finish, which gives the metal components a dark, traditional appearance. The finish complements the hardwood stock and contributes to the classic styling of the rifle.

Adjustable Trigger

The QB78-22 features an adjustable trigger, allowing the shooter to modify the trigger characteristics to suit personal preferences. An adjustable trigger can be particularly useful for target shooting because a predictable trigger pull can help the shooter maintain better control during deliberate shots.

Manual Safety

A manual safety is included as part of the rifle’s operating system. The safety provides an additional control for handling the rifle when it is loaded or when the shooter is preparing to fire.

Sighting and Scope Options

The supplied information lists front and rear sights and also references a 4×20 scope with the Rebel Air Rifle. This gives the rifle flexibility for users who prefer either conventional open sights or a magnified aiming system.

Buyers should verify whether the 4×20 scope is included with the specific package they are purchasing, as package contents can vary by model and seller.

Shooting Performance

The Beeman Rebel QB78-22 has a listed maximum velocity of 500 FPS. Its .22-caliber configuration makes it a practical choice for recreational and target shooting where users prefer a larger-caliber pellet.

The rifle’s bolt-action operation, adjustable trigger, traditional stock, and CO₂ powerplant give it a straightforward shooting platform. Rather than focusing on maximum velocity, its design emphasizes classic handling and uncomplicated CO₂ operation.

Handling and Weight

The rifle is listed at approximately 6.5 pounds and has an overall length of 39.75 inches. Its relatively full-size dimensions and hardwood stock give it the proportions of a traditional sporting rifle.

The weight can help provide a stable feel during deliberate shooting, although users looking specifically for an ultralight air rifle may prefer a lighter platform.

Factors to Consider When Choosing the Best .22 CO₂ Air Rifle

1. CO₂ Cartridge Capacity

CO₂ capacity is important because it affects how long you can shoot before replacing the cartridges. Some .22 CO₂ air rifles use one or two 12-gram cartridges, while models such as the Diana Trailscout use three cartridges and can provide approximately 100 shots per fill under stated conditions. A higher cartridge capacity can be useful for extended shooting sessions because it reduces the frequency of cartridge changes.

2. Velocity and Power

Consider the rifle’s advertised velocity and muzzle energy when comparing .22 CO₂ air rifles. The rifles discussed above range around 500 to 560 FPS, depending on the model. Velocity is only one measure of performance, however, so it is also useful to check the stated foot-pounds of energy and remember that actual performance can vary with pellet weight, temperature, and CO₂ pressure.

3. Action and Loading System

The action determines how pellets are loaded and how quickly you can prepare the rifle for another shot. Bolt-action models such as the Beeman Rebel QB78-22 and Diana Trailscout provide a traditional shooting experience, while the Trailscout also offers repeater capability. The Barra 1866 takes a different approach with its lever-action mechanism and shell-based loading. Choose an action that matches whether you prefer deliberate target shooting or a more interactive repeating experience.

4. Trigger Quality and Adjustability

A good trigger can make the rifle easier to control during deliberate shooting. An adjustable trigger, such as those found on the Diana Trailscout and Beeman models discussed above, allows the shooter to modify the trigger characteristics to suit personal preferences. When comparing rifles, look for information about trigger adjustment, consistency, and whether the trigger is single-stage or two-stage.

5. Sights and Optics Compatibility

The sighting system should match the type of shooting you intend to do. Basic front and rear sights can be sufficient for recreational shooting, while adjustable rear sights or diopter sights can provide more flexibility for target shooting. An optics rail is another useful feature because it allows a compatible scope or other optic to be installed. For example, the Diana Trailscout uses an 11mm dovetail rail, while the Barra 1866 has a removable Picatinny rail.

6. Barrel and Accuracy Features

Barrel design is another important consideration when comparing .22 CO₂ air rifles. A rifled barrel is designed to impart spin to the pellet, which can contribute to consistent pellet flight. Barrel length can also differ substantially between models; for example, the Diana Trailscout has a 19-inch rifled barrel. When assessing accuracy, consider the barrel, trigger, sights, pellet compatibility, and the manufacturer’s accuracy information rather than relying on velocity alone.

7. Weight, Length, and Stock Design

The rifle’s physical dimensions can significantly affect handling and comfort. The Diana Trailscout weighs about 5 pounds, while the Beeman Rebel QB78-22 is listed at approximately 6.5 pounds. Stock materials also affect the overall feel and appearance, with hardwood stocks providing a traditional sporting-rifle appearance and polymer stocks generally offering a different balance of weight and durability. Consider the rifle’s length, weight, grip, and stock design before choosing a model for extended shooting sessions.

8. Intended Use and Overall Features

Your intended use should ultimately guide the comparison. A rifle designed around target shooting may benefit from an adjustable trigger, precision-oriented sights, and a single-shot tray, while recreational shooters may prefer a repeater and higher shot capacity. Features such as the Diana Trailscout’s three-cartridge system, the Barra 1866’s lever-action and shell system, or the Beeman QB78-22’s hardwood stock can appeal to different types of shooters. Comparing the complete package rather than focusing on one specification can help you select a .22 CO₂ air rifle that matches your shooting preferences.
