Specna Arms AK SA-J22 Flex AEG Assault Carbine - Black

Electric replica of an assault carbine from the Flex series, designed for dynamic airsoft games, where ergonomics, low weight, and the ability to expand with additional equipment matter.

The structural elements have been matched with great precision, which translates into a high work culture and smooth operation of the mechanisms. The model combines realistic implementation, modern electronics, and practical solutions that will be appreciated by both beginners and experienced players.

damage-resistant construction

Most of the replica's elements are made of durable yet lightweight polymer, which allowed to reduce the weight of the entire construction. Metal was used to produce components most exposed to mechanical loads, including the muzzle device, outer barrel, a dummy gas tube, and front sight elements.

The polymer handguard is equipped with mounting rails allowing for the installation of additional accessories, such as tactical lighting, laser pointer, or collimator. The body and the cover of the locking chamber are also made of polymer, on which an adjustable peep sight is placed.

double-sided manipulators for comfortable handling

The model is equipped with double-sided manipulators increasing the convenience of handling for both right- and left-handed shooters. The steel fire selector is equipped with a special notch allowing for the locking of the bolt in the rear position. The replica also uses 2 types of magazine release - an enlarged and a winged one placed near the cross guard.

stock adjustable in 6 positions

The carbine is equipped with a stock with length adjustment in 6 positions, which allows configuration of the replica to be adapted to the shooter's silhouette and the tactical gear used. The folding construction facilitates transport and improves maneuverability during operations in confined spaces. An adjustable cheek pad is placed on the stock.

gearbox v3, hop-up system, internal components

The replica is equipped with gearbox v3 and allows for single, continuous, and controlled fire. The model generates an initial velocity level of about 350 FPS. The carbine is equipped with a Hop-Up system, which ensures stable spin of the BBs. The muzzle device is mounted on a 14 mm CCW thread allowing for the installation of suppressors or tracers.

A series of components increasing durability and work culture of the system were used inside. The construction includes, among others, a polymer piston with a steel rack, a ventilated piston head, sealed nozzle, type 2 steel cylinder, and an aluminum spring guide equipped with bearings. The whole mechanism operates on bushings supporting the stability of the mechanism.

SA ETU electronic system

The carbine is equipped with an electronic system SA ETU allowing for the configuration of selected functions. The system allows, among others, the setting of fire modes and pre-cocking function, which enables adjustment of the replica's work characteristics according to the user's preferences and the type of gameplay.
