CARBINE M4 SA-B02 BLACK / TAN SPECNA ARMS (SPE-01-006109)

The replica was very well adapted in a way that was previously only observable in G&P or Classic Army class replicas. It was also perfectly balanced. This ensures perfect handling of the replica while the weight is almost not felt when placing the replica on the shoulder.
The replica uses a rapid spring exchange system, the so-called Enter & Convert ™. This allows for a quick and fluent adaptation of the replica's power to battlefield conditions without the need to access a workshop or a number of specialized tools - when pulling the gearbox out of the replica body, the process of swapping the main spring literally takes seconds.
The benefits of the Enter & Convert ™ system are hard to overestimate. In light of the existing laws in Europe that limit the speed of the sprint of the replica and of the establishments within the airsoft company, this system guarantees the user great possibilities and more freedom. The Enter & Convert ™ system allows you to change the mainspring in a short time and, what follows, adjusts the muzzle speed of the replica on the battlefield in order to guarantee a perfect compromise between the effectiveness of firing and the safety of yours and others players.
The replica has been fully adapted to work with LiPo and LiFe batteries. Thanks to the base muzzle speed of around 410 FPS, guaranteed by the default mainspring, the replica is perfect for use at medium distances. The set also includes an M90 mainspring which allows the muzzle velocity to be reduced to around 310 FPS, making the replica perfectly suited for short range operations or fighting inside buildings.
The reinforced reducer at the height of the cylinder head hides a steel main spring guide which is the element of the Enter & Convert ™ system and also the 8 mm ball bearings and steel grinding wheels positioned on the spacers. The system is protected with the use of four anti-reversals. The lightweight polycarbonate piston features a steel tooth to increase durability. There is a type 2 cylinder and steel hammer and metal coupling chamber applied in this replica.

The updated version comes with some new improved internal parts:
reinforced steel gear set
steel spring guide
light polymer piston
aluminum, sealed piston head
metal head
metal nozzle with air seal

The replica is equipped with a 22mm RIS rail, a set of 22mm RIS rails and an adjustable stock. The top RIS rail holds the flip-up type iron sights which can be easily detached and replaced with any optical-electronic aiming device. Thanks to the folding stock that ends with a non-slip butt stock, the length of the replica can be adapted to the build and preferences of the shooter. The default flash hider is placed on a 14mm counterclockwise thread which allows a sound suppressor to be attached in its place.
In order to increase the level of realism, the replica has been equipped with a functional bolt stop lever.
The replica set also includes a high-capacity steel magazine that holds 300 BB pellets.

The set does not include the battery or charger.
