Specna Arms SA-H02 ONE™ Airsoft Automatic Carbine Replica
High-Quality Replica with Quick Spring Change System
The SA-H02 carbine replica from Specna Arms is made of zinc and aluminum alloy, with steel elements used in the most vulnerable points of the replica (all screws, pins, and sling swivels). The SF-type stock accommodating the battery and the pistol grip are made of polymer plastic. The replica's body and RIS rails have been anodized, which guarantees a high degree of protection against corrosion. The painting of the replica itself was done by powdering, after sandblasting the surface. This ensures a much higher abrasion resistance than usual for the applied paint. Manufacturer's markings are found on the receiver.
The replica has been adapted very well - in a way almost exclusively observed in G&P or Classic Army manufacturers - and is perfectly balanced. This ensures perfect maneuverability for the replica, and its weight is almost unnoticeable after placing the replica on the shoulder.

Quick Spring Change System - Enter & Convert™
The replica uses a quick spring change system, the so-called Enter & Convert™. This enables quick and efficient adjustment of the replica's power to the conditions expected in the game field without needing access to a workshop or a number of specialized tools. After removing the gearbox from the replica's body, the process of replacing the spring itself literally takes a few seconds. Visit our airsoft rifle category to view similar products.
The advantages of the Enter & Convert™ system cannot be overstated. In light of the tendency prevailing throughout Europe to apply legal limits to the replica's muzzle velocity, this system provides the user with considerable opportunities and a lot of freedom. The ESA™ system allows you to quickly, with little or no effort, change the main spring and thereby adjust the replica's muzzle velocity to the requirements of the game organizer. This guarantees an ideal compromise between the effectiveness of firing your shots and your own safety and the safety of other players.

Adapted for LiPo and LiFe Batteries
The replica is fully adapted to work with LiPo and LiFe batteries. Thanks to the basic muzzle velocity of ~410 FPS guaranteed by the factory-installed main spring, the replica is perfect for mid-range operations. The set also includes an M90 spring, which allows you to reduce the initial muzzle velocity to ~310 FPS, making it a replica perfectly adapted to operate at close distances or inside buildings.
- Steel spring guide (part of the Enter & Convert™ system)
- Steel gears mounted on 8mm ball bearings
- Four anti-reversal latches
- Type 2 cylinder and a steel switch
- Precise, rotary, polymer Hop-Up chamber
The replica is equipped with a 22mm RIS rail, a set of front RIS rails, and an adjustable stock. Flip-up metal sights are mounted on the upper RIS rail, but they can be easily replaced by other optoelectronic sights. Thanks to the adjustable stock with a non-slip texture stock, it is possible to adjust the length of the replica to the body type and the operator's preferences. The standard flash hider is mounted on a 14 mm left-hand thread, which allows you to attach a silencer in its place.
To increase realism, the replica is also equipped with a working bolt release mechanism.
The set with the replica also includes a steel hi-cap magazine with a capacity of 300 BBs.

- Replica
