SA-A03 carbine replica - Half-Tan

The Specna Arms brand SA-A03 carbine replica made predominantly of an homogenous alloy of zinc and aluminum with the use of steel elements in the most neuralgic points of the replica ( the screws, the pins and the tactical sling attachment points are made of steel ). The SF type stock which holds the battery and the pistol grip were made of polymer plastic. The replica’s body, the RIS rail set were a subject to the process of anodizing what guaranties a high level of protecting the replica against corrosion. The paintjob of the replica itself was made using the pulverization method after a previous sandblasting of the replica’s surface. This ensures the paint’s higher, than usually, durability against abrasion. The replica’s body beads the USMC markings.

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 tochange 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. 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 threadwhat 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.

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.

I am really disappointed, I bought this replica thinking that I had the Saec system, I even put it in the box but today when trying to change the dock I discovered that it does not have the Saec system. It's a shame the replica is very good in all its aspects but I've taken a dislike since I'll have to take it to a mechanic.

Sounds and shoots well, good accuracy at 40 meters, external materials are not very good, both plastic and metal are of questionable quality and not too well finished, although outside is all well adjusted I can not say the same about inside, since hop up chamber is moving on its axis, best of all the good service of gunfire.

This is my first M4. I am pleased with the quality. Feels like real weapon. Little sidenote: this version does not have the quick spring change option.

Fantastic rifle. It's unbelievable given the price that you can get a full metal rifle with such cracking accessories. So far as I can tell the gearbox is spot on with a good rate of fire straight out of the box. Easily upgradable and compatible with Tokyo Marui parts. I've already swapped out the hop for a Prowin one and it's shooting straight as a die over 40m.

Great replica! Top quality for a bottom price. Can easily be upgraded. For Dutch fps limitations the included 90 spring is great, but a 100 or even 110 spring is also recommended.

Great replica, especially if you don't want to spend to much. Can easily be upgraded in the futere, but it's good enough out of the box. Almost full metal and very sturdy, this one won't break easy. Might need some grease in the gearbox as mine was almost dry.

Great gun, got it a few days ago and im happy to say it works great haha. Almost full out of metal except for the pistol grib (that feels really sturdy so no problem there) and a plastic butstock the only thing that looks kinda cheap but easy to replace. battery fits great no problems at all. tried it out and i can even hit a target (head sized) at 40 meters away. Wel it feels and looks great defenitly worth every penny!
