Hatsan Invader Auto OD 5.5 mm PCP air rifle

Hatsan Invader Auto OD Green is a modern PCP air rifle with a Semi Auto Action system, allowing rapid follow-up shots without manual reloading after each trigger pull. This model features a precision rifled and choked barrel with a full shroud, a tactical OD Green stock, a 22 mm Picatinny mounting rail, fiber-optic sights, a manual safety, and a 255 cc aluminum air cylinder. Available in the following calibers: .177 (4.5 mm), .22 (5.5 mm), and .25 (6.35 mm).

Semi Auto Action - the semi-automatic operating system enables consecutive shots without the need to reload manually with a lever each time. After the trigger is pulled, the mechanism automatically prepares the air rifle for the next shot, enhancing the pace and dynamics of recreational and sport shooting. For proper system operation, the manufacturer recommends a minimum cylinder pressure of 100 bar.

Barrel - a precision rifled and choked barrel measuring 19.7" (500 mm), fully enclosed in a metal shroud. This design improves structural rigidity, supports stable pellet guidance, and helps achieve tight shot groupings. The narrowing at the muzzle, known as choking, contributes to precise pellet stabilization and improved accuracy.

Power source - powered by compressed air from a removable aluminum cylinder with a capacity of 255 cc, filled to 200 bar. A fully charged cylinder delivers up to 50 semi-automatic shots at optimal velocity, depending on caliber and shooting conditions. The built-in pressure gauge allows the shooter to monitor the air pressure inside the cylinder, while the rotating fill-port cover protects the filling port from dirt and debris. The set includes a quick-fill connector and a plug for safely depressurizing the cylinder.

Stock - tactical, synthetic, and finished in OD Green, designed for comfortable use by both right- and left-handed shooters. The ergonomic pistol grip, thumbhole design, and adjustable cheek rest allow the air rifle to be better fitted to the shooter’s build and the type of optic being used. The buttstock is finished with a rubber buttpad for enhanced shouldering stability. The stock also includes a storage slot for carrying one spare magazine.

Mounting rail - the upper 22 mm Picatinny rail allows mounting an optical sight or red dot sight. In addition, the air rifle is equipped with three Picatinny accessory rails located under the forearm and on both sides, making it possible to attach additional shooting accessories.

Magazine - detachable, rotary magazine with a capacity of 14 pellets in 4.5 mm / .177 caliber, 12 pellets in 5.5 mm / .22 caliber, and 10 pellets in 6.35 mm / .25 caliber. The set includes three magazines, allowing for longer shooting sessions without frequent pellet reloading.

Sights - the air rifle is equipped with a detachable carry handle featuring an integrated fiber-optic rear sight adjustable for windage and elevation. The fiber-optic front sight with height adjustment is located at the front of the rifle. This setup allows the air rifle to be used even without an additional optical sight.

Trigger and safety - the manual safety helps prevent an unintended shot. The air rifle features a black metal trigger blade and a patented anti-knock system, which protects against accidental discharge in the event of impact or shock.

Additional equipment - this model includes sling swivel studs for mounting a carrying sling, a detachable carry handle, three magazines, a quick-fill connector for filling the cylinder, and a plug for depressurizing the air tank. The removable cylinder design allows the use of spare air cylinders available as optional accessories.

Each air rifle not exceeding 17 J is supplied by the manufacturer with a unique 17 J Energy Limit Certificate. The certificate is a document confirming the product’s compliance characteristics and, therefore, the legality of the air rifle under Polish regulations. Air rifles legally imported into the Polish market bear the marking of the exclusive distributor, Sharg.
