Airsoft Rifle SA-K04 Specna Arms
SA-K04 assault rifle replica by Specna Arms is made largely from a uniform zinc and aluminium alloy, reinforced with steel elements in the most vulnerable points of the replica (steel elements - all the screws, pins and tactical sling swivels). Both the SF stock storing the battery and the pistol grip were made from polymer. The receiver of the replica and RIS handguard have undergone the process of anodizing, which guarantees high degree of protection against corrosion.
The paint was applied via a process of powder coating, after having the surface undergo the process of sandblasting prior to the application of paint. This provides a much higher than usual resistance of the applied paint to abrasion. The receiver bears USMC markings.
The replica is fully compatible with LiPo and LiFe batteries. Due to base muzzle velocity of ~410 FPS provided by the main spring installed by default by the manufacturer, the replica is perfect for operating on a medium range. The set also includes an M90 spring, which allows to reduce the muzzle velocity to ~310 FPS and as a result to adapt the replica for close-ranged and indoor operations.
The gearbox which is reinforced on the height of the cylinder’s head hides a steel main spring guide which is the element of the Enter & Convert™ system and also 8mm ball bearings and steel thread-wheels which are placed on spacers. The system is secured with the use of four anti-reversals. There is a type 2 cylinder and the steel breaker and a metal hop-up chamber applied in this replica.
CHANGE THE SPRING IN 45 SECONDS
Like all Specna Arms models, the CORE line is also equipped with a quick spring change system. It is not necessary to remove the gearbox from the replica to replace the spring, all you have to do is remove the stock tube by unscrewing a single screw, unscrew the spring guide pin and replace the spring. The whole operation takes about a minute and only a screwdriver.
Specna Arms airsoft rifles are the perfect choice for players of all skill levels. They are equipped with innovative features and an unbeatable value for money that makes them particularly attractive.
The Upgraded Version is equipped with some new, improved internal parts_
- set of reinforced steel gears
- steel spring guide
- lightweight, polymer piston
- aluminum, sealed piston head
- metal cylinder head
- air seal metal nozzle
The replica is equipped with a 22 mm top RIS rail, Free Float handguard and an adjustable stock. The top RIS rail features metal flip-up iron sights, which can be freely detached in order to make room for the attachment of a chosen optoelectronic aiming device. Due to the extendable stock with an anti-slip stock pad it is possible to adapt the replica’s length to the body type and preferences of the user. Standard flash hider is based on 14 mm left-handed thread, which allows the attachment of a silencer in its place. What’s more, the set includes a silencer with a QD mount ideally fit for the handguard of the replica.
The replica was adapted for use by both right- and left-handed users thanks to the installation of a double-sided fire mode selector and magazine release button as well as, what is a rare occurrence, a double-sided slide release button. These may seem like miscellaneous elements, however, they increase the overall realism of imitation of the original as well as pure ergonomics of usage. Noteworthy is also the original trigger guard with the model marking.
The replica comes with a steel, 300 BB, Hi-Cap magazine.

The set does not include the battery nor charger.
