5 Best Semi-Automatic Air Rifle
1. Hatsan Invader Auto Semi-Automatic PCP Air Rifle, .22 Caliber
The Best Semi Automatic Air Rifle needs to combine dependable PCP operation, practical handling, useful accessory mounting options, and consistent performance. The Hatsan Invader Auto Semi Automatic PCP Air Rifle in .22 caliber is designed around these requirements, offering a semi automatic PCP platform with a fixed 255cc air cylinder, a built in pressure gauge, and a 36 round capacity. Its black advanced polymer frame also keeps the design focused on durability and practical handling.
One of the main features of the Hatsan Invader Auto is its semi automatic PCP action. Instead of requiring a manual cocking operation for every shot, the system is designed to cycle automatically, making the rifle more convenient to operate. The .22 caliber configuration provides a balance between pellet size and the rifle’s stated performance, while the manufacturer lists a maximum muzzle energy of up to 34 FPE. Actual velocity and energy can vary depending on pellet characteristics, temperature, elevation, and other conditions.
The rifle uses a fixed 255cc air cylinder rated at 200 BAR and includes an integrated pressure gauge. This gives the shooter a convenient way to monitor the rifle’s air supply. Hatsan also incorporates an anti knock system designed to reduce unnecessary gas loss if the rifle is knocked or bounced. This is a useful consideration for a PCP platform because efficient air management can affect how conveniently the rifle can be used between refills.
Another useful aspect is the optics and accessory mounting arrangement. The Invader features a combination 11 mm and Picatinny optics rail, along with three additional built in Picatinny rails for accessories. This provides flexibility for configuring compatible equipment according to the user’s requirements. The removable one piece carry handle also incorporates adjustable open sights, giving the rifle an additional sighting option without requiring an optic.
The design includes an advanced polymer frame and an alloy steel barrel. At 8.2 pounds, it is not an especially lightweight air rifle, so buyers should consider whether that weight suits their intended use. The stock also incorporates magazine storage, which can provide a convenient place to keep an additional magazine available when needed. The stated magazine capacity is 36 rounds.
According to the supplied specifications, the rifle can reach up to 1,100 FPS with lead free pellets and up to 1,000 FPS with lead pellets. These figures should not be treated as guaranteed performance because pellet weight, shape, material, temperature, elevation, and other factors can change actual results. The combination of semi automatic PCP operation, a relatively large air cylinder, accessory rails, and a high capacity magazine makes the Hatsan Invader Auto a feature rich option for buyers looking for a .22 caliber semi automatic air rifle.

3. Crosman 1077 RepeatAir Semi-Automatic .177-Caliber Pellet Air Gun
The Crosman 1077 RepeatAir Semi-Automatic .177-Caliber Pellet Air Gun designed for users who want a lightweight and straightforward repeating airgun. Its semi automatic action provides convenient follow up shots, while the rifled steel barrel is designed to support accuracy with .177 caliber pellets. The rifle uses a 12 gram CO2 cartridge and can reach stated velocities of up to 780 FPS, making it a practical option for backyard shooting and general target practice where permitted.
A major feature of the Crosman 1077 is its CO2 powered operating system. Instead of requiring a PCP air tank or manual pumping, the rifle uses a 12 gram CO2 cartridge to provide its operating power. This makes the platform relatively simple to use, although the cartridge is not included with the rifle. The CO2 system also contributes to the rifle’s repeating capability, allowing users to fire successive shots without manually cocking the rifle after every shot.
The rifled steel barrel is another important component. Designed for .177 caliber pellets, the rifling helps stabilize the pellet as it travels through the barrel. Crosman positions the rifle for backyard distances, making the design more appropriate for recreational target shooting than applications requiring a heavier caliber platform. The supplied information also highlights hollow point pellets with an expanding tip design, although pellet performance can vary depending on the specific ammunition used.
The rifle features a water resistant synthetic stock designed for outdoor use. Synthetic construction can be useful for users who want a practical platform that does not require the same level of care as some traditional stock materials. The design also keeps the rifle relatively straightforward, making it suitable for shooters looking for a simple repeating airgun.
With a stated maximum velocity of 780 FPS, the Crosman 1077 provides a useful level of performance for its .177 caliber configuration. However, maximum velocity figures should not automatically be interpreted as the performance users will achieve under every condition. Pellet type, weight, temperature, and CO2 pressure can all influence actual velocity. Buyers should therefore consider the manufacturer’s velocity figure as a stated maximum rather than a guaranteed result.
