Specna Arms SA-B05 ONE™ SAEC™ System Carbine Replica

SA-B05 SAEC™ System Assault Rifle Replica

SA-B05 assault rifle replica by Specna Arms is made largely of a uniform zinc and aluminum 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 of polymer. The receiver of the replica and the RIS handguard have undergone the process of anodizing, which guarantees a 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’s parts are very well aligned – in a way that could be thus far noticed solely in replicas by such top-tier manufacturers as G&P or Classic Army, the replica is also perfectly balanced. This allows for an almost ideal maneuverability of the replica and its weight is almost unnoticeable once the replica has been shouldered. 

The replica features a new generation quick spring release system, so-called SAEC™. Due to that system, it is possible to rapidly and quickly adapt the power of the replica to the conditions expected on the playing field without the necessity to have the access to a workshop or a set of special tools. The spring change process is even faster than in the case of the previous version of the system.

Thanks to SAEC™ System, there is no need to take out the gearbox from the replica – all that is required is to remove the stock slide (no tools are necessary – it is attached with a tightened ring and a latch), afterward it is necessary to loosen the located underneath pin along with a bearing-mounted spring slide. We exchange the main spring, screw in the pin back in the body, attach the stock and… we’re back in the game! The entire operation lasts but a moment and, let us say it again, does not require the use of any tools.

The advantages of SAEC™ system are hard to overstate. In the light of the current tendency in the whole Europe to use legal limitations regarding the muzzle velocity of replicas or internal regulations inside various groups, the system guarantees the User a varied set of possibilities and plenty of freedom. SAEC™ system allows with a minimal amount of time to change the main spring, thusly customize the muzzle velocity towards the area of the game in such a way so as to guarantee an ideal compromise between the effectiveness of fire and safety for the User himself as well as other participants.

The replica is fully compatible with LiPo and LiFe batteries. Due to the base muzzle velocity of ~430 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.

A reinforced at the cylinder level gearbox contains a steel spring slide that is an element of SAEC™ system and mounted on 8 mm ball bearings and washers steel gears. The system is secured with four anti-reversal latches. A light, made of polycarbonate polymer piston is equipped with a set of steel teeth in order to increase its durability. Also implemented were a type 2 cylinder and a steel circuit-breaker, as well as a metal Hop-Up chamber.

The upgraded version features an array of new, reinforced parts such as:

– set of reinforced, steel gears
– bearing-mounted, steel spring slide
– light, polymer piston with a steel strip
– aluminum tightened piston head
– metal cylinder head
– tightened, metal nozzle

The replica is equipped with a 22 mm top RIS rail, RIS 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. A standard flash hider is based on a 14 mm left-hand thread, which allows the attachment of a silencer in its place.

In order to enhance the realism of the game, the replica also features an operational bolt-catch mechanism.

The replica comes with a steel, 300 BB, Hi-Cap magazine.

Specna Arms replicas are compatible with many magazines available on the market, from manufacturers like:
– BOYI,
– Airsoft Systems,
– SRC,
– King Arms,
– MAG,
– STAR,
– ACM.

SAEC™ system is included in the European Patent with a number: 002639500
