SA-K02-M carbine 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). The stock, the pistol grip and the magazine were made from 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 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 quick spring exchange 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 the 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 plenty of freedom. Enter & Convert™ system allows with a minimal amount of time to exchange the main spring, thus to 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 a base muzzle velocity of ~420 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 guide that is an element of Enter & Convert™ system and mounted on 8 mm ball bearings and washers steel gears. The system is secured with four anti-reversal latches. 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
- steel spring guide
- lightweight, polymer piston
- aluminum air-sealed piston head
- metal cylinder head
- air-sealed, metal nozzle
The replica is equipped with a 22
mm top RIS rail and a RIS handguard in classic, four-side configuration. The
top rail features a flip-up rear sight, while the front sight was mounted on
the external barrel. 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-handed thread,
which allows the attachment of a silencer in its place.
The replica was adapted for use by both right- and left-handed users thanks to the installation of a double-sided fire mode selector and magazine release button as well as, what is a rare occurrence, a double-sided slide release button. These may seem like miscellaneous elements, however, they increase the overall realism of imitation of the original as well as pure ergonomics of usage. Noteworthy is also the original trigger guard with the model marking.
The replica comes with a polymer, 300 BB, Hi-Cap magazine.
Specna Arms replicas are compatible with many magazines
available on the market, from manufacturers like:
- Airsoft Systems,
- King Arms,
The set does not include a battery or a charger.
The set includes:
- fixed iron sights
- additional main spring
to report number HKGEC1600157401, the product meets the
requirements of European Union RoHS - Restriction of Hazardous Substances
2011/65/EU directive annex II as well as 2002/95/EC amending directive concerning the limitation of the number of hazardous substances in electronics.
Which means that Specna Arms free from harmful materials such
- hexavalent chromium
- polybrominated biphenyl (PBB)
- polybrominated diphenyl ether (PBDE)
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
~420 / ~310
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.

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).

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.
ZnAl + steel + plastic
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.
