Specna Arms SA-A01 Assault Rifle Replica

SA-A01 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
 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 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 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 ~410 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 Enter & Convert™ 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 steel tooth 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
- steel spring guide
- lightweight, polymer piston
- 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.

Gearbox version:

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.

Battery included:

NiCd 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.
NiMH batteries have a higher self-discharge over time and shorten the life - on the other hand, they earn about 30% more capacity.

Magazine type:
Hi-Cap magazine
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).

Yes, adjustable
Blow Back:

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.

Very sturdy full metal replica. Shoots great out of the box. Shoots even better with just a few upgrades. Recommend the brand!

Superb gun! Shoots at 150 m/s and has 50m effective range out of box. Solid body and decent internals although gearbox really needs some greasing. A fantastic starter gun! Shoots pretty consistently although with the hop-up all the way off BBs still tend to get quite bit of backspin. Worth every penny! Here's a picture gallery of gun and internals:

Full Metal, sturdy replica. I have put only about 1000 bbs through it until now, but what i can tell very reliable and good shooting trajectory. Havent changed the spring yet, but seems reasonably easy. For what I can tell, very good price- quality balance.
