SA-B04 ONE™

Description

Specna Arms SA-B04 Carbine Replica - Half Brown

The replica of the Specna Arms SA-B04 carbine is mainly made of a homogeneous alloy of zinc and aluminium, using steel elements at the most neuralgic points of the replica (the screws, the pins and the attachment points for the tactical sling are made of steel). . The SF-type stock, which holds the battery, and the pistol grip were made of polymer plastic. The body of the replica and the RIS rail set were subjected to an anodising process, which ensures a high degree of corrosion protection of the replica. The painting of the replica itself was done in a pulverisation process after previously sandblasting the surface of the replica. This ensures a higher than usual abrasion resistance of the paint.

The replica was very well fitted - in a way previously only seen in G&P or Classic Army class replicas. It was also perfectly balanced. This ensures perfect manoeuvrability of the replica, as its weight is hardly noticeable when placing it on the shoulder.

The replica uses a quick mainspring change system called Enter & Convert™. This allows for quick and smooth adjustment of the replica's performance to battlefield conditions without the need for access to a workshop or a range of specialist tools - when you remove the gearbox from the replica's housing, the process of replacing the mainspring takes literally seconds.

The advantages of the Enter & Convert™ system are hard to overestimate. Given the laws in force in Europe that limit the muzzle velocity of the replica and the facilities within the airsoft society, this system guarantees the user great possibilities and more freedom. The Enter & Convert™ system allows the mainspring to be changed in a short time and then adjusts the muzzle velocity of the replica to the battlefield, ensuring a perfect compromise between shooting effectiveness and safety of your rifle own and other players.

The replica has been fully adapted to work with LiPo and LiFe batteries. Thanks to the basic muzzle velocity of approx. 410 FPS guaranteed by the standard main spring, the replica is perfectly suited for use at medium distances. The set also includes an M90 mainspring that allows the muzzle velocity to be lowered to around 310 FPS, making the replica perfect for short-range operations or fighting inside buildings.

The gearbox, reinforced at the level of the cylinder head, conceals a steel main spring guide that is part of the Enter & Convert™ system, as well as 8 mm ball bearings and steel threaded gears placed on spacers. The system is secured by the use of four backstops. There is a Type 2 cylinder and the steel breaker. Replica is factory-equipped with a precise rotating hop-up unit made of polymer, which allows very precise and stable regulation of the BB overclocking.

The updated version is equipped with some new, improved internal parts:

- Set of reinforced steel gears
- Steel spring guide
- Lightweight polymer flask
- Aluminium, sealed piston head
- Metal cylinder head
- Airtight metal nozzle

The replica is equipped with a top 22 mm RIS rail, a set of front 22 mm RIS rails and an adjustable stock. On the upper RIS rail are the hinged iron sights, which can be easily removed and replaced with any optical-electronic sights. Thanks to the collapsible stock, which ends with a non-slip stock foot, it is possible to adjust the length of the replica to the shooter's build and preferences. The standard flash hider is mounted on a 14 mm counterclockwise thread, allowing a silencer to be fitted in its place.

To increase the degree of realism, the replica was equipped with a functioning breech catch lever.

The replica set also includes a Hi-Cap steel magazine with 300 BB cartridges.
