Specna Arms SA-B02 carbine replica
The replica was fitted very well – in a way that it was previously observable only in the G&P or Classic Army class replicas. It was also perfectly balanced. This ensures a perfect maneuverability of the replica while as its weight is almost not felt when you place the replica on the shoulder.
The replica uses a quick main spring exchange system, the so-called Enter & Convert™. This allows for a quick and fluent adaptation of the replica’s power to the conditions of the battlefield without the need of having access to a workshop or a number of specialist tools – when you take the gearbox out the replica’s body, the process of exchanging the main spring takes literally seconds.
The advantages of the Enter & Convert™ system are hard to overestimate. In the light of the laws existing in Europe and which limit the muzzle velocity of the replica and the establishments inside the airsoft society, this system guaranties the user great possibilities and more liberty. The Enter & Convert™ system allows to change the main spring in little amount of time, and, what is followed by this, adapted the muzzle velocity of the replica to the battlefield so it guaranties a perfect compromise between effectiveness of firing and the safety of your own and other players.
The replica was fully adapted to cooperate with LiPo and LiFe type batteries. Thanks to the basic muzzle velocity of about 410 FPS which is guaranteed by the default main spring, the replica is perfect to be used in middle distances. The set also includes an M90 main spring which allows to decrease the muzzle velocity to about 310 FPS making the replica perfectly adapted for short range operations or fighting inside buildings.
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. The light, polycarbonate piston is equipped with a steel tooth in order to increase its durability. There is a type 2 cylinder and the steel breaker and a metal hop-up chamber applied in this replica.
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 top 22mm RIS rail, a set of front 22mm RIS rails and an adjustable stock. The top RIS rail holds the flip-up type iron aiming sights which can be easily detached and replaced with any optical-electronic aiming devices. Thanks to the collapsible stock which is ended with a anti-skid stock’s foot, it is possible to adapt the replica’s length to the built and the preferences of the shooter. The default muzzle flash-hider is placed on a 14mm counter-clockwise thread what allows the attachment of a sound suppressor in its place.
In order to increase the realism level, the replica was equipped with a functional bolt catch lever.
The replica set also includes a steel hi-cap type magazine which holds 300 BB pellets.

This is a value that includes the weight of the replica, magazine and other accessories that are include in set without a battery, charger, cleaning rod, etc., etc.
rechargeable battery is characterized by high efficiency

Hop-Up system is used for overclocking bb during the shot (putting it in rotation), through which, it extends its flight path. Acting laws of physics make that bb lift up, while the gravitational force take it down. Appropriate adjustment of Hop-Up, will compensate for these two factors, which result in long and straight flight for longer distance and be greater focus shot (to improve accuracy).
Blow back is a simulation system of the cocking lever - it imitates the work of it as the equivalent sharp. This system raises the realism and adds a lot more experience during shooting.
