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.

Great replica out of the box. Well made, solid, no movement/gaps between eternal parts. It has some quirks, such as the weak hop-up unit, internal barrel, motor, but these are mostly the same on all replicas out of the box. However if you want an exceptional replica, change the inner barrel, hop-up unit, nozzle, add a high torque motor and an ASCU unit and you have a truly amazing toy. After the above upgrades, the replica performs with 131 constantly with a spring of M120.

The spring of the front iron sight breaks really fast indeed and doesn't even work properly, the second problem that was described up above is fixed easily and doesn't require a precision barrel to be mounted on the gun. It is a nice addon though but the problem why the BB's curve to the right and left is because the piston inside of the gearbox is quite loose and because on it, I found is a little plastic residue that you can easily remove. I opened up my gearbox and change the spring while making sure the piston is almost impossible to push in. This fixes the curving of the bullets from left to right and now it shoots perfectly. I sincerely reccomend this gun if you want a starter gun and know how to fix this problem described up above.

nice replica for a good price. The standard hop-up rubber + bucking is slightly lacking and the stock innerbarrel is roughly finished. The replica has decent internals and a good strudy feel to it.

Very good replica. Rail cover are nowhere near TAN, but a little spray paint will fix this issue. Shoots great, haven't fielded it yet.

Great gun for it's price, really nice finish. Hop up unit isn't great but they are easily replaced and maybe upgrade the barrel for better accuracy.

This is a good entry price replica. It has only 2 problems, the spring of the front iron sight broke after few hours of the unboxing, the second problem is that it doesnt shoot accurate after 50 meters. The bb starts curving left or right and can be fixed with a precicion barrel
