The Specna Arms SA-A05 is there version of the MK18 M4 carbine and is 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 body, the RIS rail set were a subject to the process of anodizing what guaranties a high level of protecting the AEG against corrosion. The lower receiver has USMC markings.
Theis AEG is well built and both parts of the receiver fit very well – in a way that it was previously only seen in the G&P or Classic Army. It is also perfectly balanced. This ensures a perfect maneuverability while playing.
The gearbox 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 to change the main spring in little amount of time, and, what is followed by this, adapted the muzzle velocity of the AEG to the site FPS limit.
The gearbox is capable and ready for LiPo and LiFe type batteries. Thanks to the basic muzzle velocity of about 410 FPS which is due to the default main spring, the aeg is perfect to be used in middle distances, but may be considered over power for most UK sites without it being locked to semi auto. Also included is a M90 main spring which once installed will put the FPS to about 310 FPS making the AEG UK site friendly.
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. The Lekki, polycarbonate piston is equipped with a steel tooth in order to increase its durability. There is a type 2 cylinder and the steel breaker and a metal hop-up chamber installed.
It 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 thread what allows the attachment of a sound suppressor in its place.
In order to increase the realism level, its equipped with a functional bolt catch lever.
