Specna Arms SA-B11 URX Assault Rifle Replica
SA-B11 URX 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 hand guard 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 same process 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 fit very well together - 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 almost ideal maneuverability of the replica and its weight is almost not noticeable once the replica has been shouldered.
The replica features a quick spring release system, so-called Enter & Convert™. 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 access to a workshop or a set of special tools - once the gearbox has been taken out of the replica’s body, the process of spring change lasts literally seconds.
The advantages of Enter & Convert™ 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 much freedom. Enter & Convert™ system allows with minimal amount of time 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 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 base muzzle velocity of ~400 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 ~300 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.
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 hand guard 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-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.

Replika karabinka Specna Arms SA-B11
It is the spped of bb, while its leaving the innerbarrel of replica. This speed is measured in FPS (Feet Per Second).
1 FPS = 0,3 m/s
1 J = 99 m/s
1 J = 326,7 FPS
~300 - 400
|Propulsion / Powered by:|
Indications v2, v3, v6 does not mean the level of advance, but only shape of gearbox skeleton which was used and selected by the manufacturer depending on the capabilities of the body of the replica. For example, a models of the M4/M16 family, MP5, have a v2 gearbox, while the AK family have gearbox v3.
|Type of fire:|
The length of the replca is measured between the two most distant points of each other. Different models have several of these values, because of its design allows to increase or decrease it length (eg. folding stock or extended flash hider).
660 - 745
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.
|Magazine capacity [pcs]:|
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.
Metal + plastic + steel
rechargeable battery is characterized by high efficiency
current-carrying capacity, but there are disruptive effect on memory.
Should be unloaded and loaded in the full cycle, ie, it is recommended
to fully discharge, and after unloading must charge the battery
immediately without leaving it for a long time in a discharged state.
