Specna Arms AK SA-J21 FLEX AEG assault rifle

An airsoft assault rifle from the manufacturer Specna Arms was created as a result of a collaboration with the Well Pro manufacturer.
The SA-J21 model is made mainly using a durable polymer, and the most stressed parts here are made of metal.
The replica has a metal discharge device mounted on a 14mm CCW thread. Then there is the metal outer barrel, the dummy gas tube and the musket (the musket elements are partly made of steel). The polymer stock will not only provide a stable grip when handling the rifle, but at the same time, thanks to the mounting rails, it will allow for expansion with additional accessories such as a vertical grip, lasers, torches, red dot sights, etc. The cover of the locking chamber and the body of the replica are also made of polymer. At the top of the cover, there is a mounting rail and a front sight, which has a simple but effective adjustment. Stopping for a moment at the body - it is worth noting the two-sided manipulators. We are talking about both the fire selector (steel, with an indentation allowing the slide to be locked in the rear position) and the magazine release (enlarged as in AK replicas, but also winged, mounted at the breech). Finally, we find the folding buttstock, which is adjustable in 6 degrees. On the butt there is a cheek piece, which will also be customisable.

Inside the replica we will find, among others:
- Polymer piston with steel jaw
- Slide bearings
- Vented polymer piston head
- Polymer sealed nozzle
- Polymer cylinder head
- Type 2 steel cylinder
- Aluminium, bearing spring guide
- SA ETU

The SA ETU mounted inside the replica will make the replica adaptable to a specific scenario, easily setting specific fire modes or pre-cocking.

The SA-J21 FLEX is a rugged AEG assault rifle that has been designed not only for beginners, but also advanced users and fans of the AK platform, which will be easily expandable. The lightweight, ergonomic design will allow for efficient movement on the airsoft field and folding up to shoot, without worrying about losing the strength that will be needed during intense gameplay.
An additional advantage of the rifle are the markings on the side of the body 6P70 and the calibre 5.45x39, which is a nod to fans of realism.
