The Specna Arms SA-A37 carbine replica is made for the most part from a uniform zinc and aluminum alloy, using steel elements at the most sensitive points of the replica (so all screws, pins and tactical suspension handle are steel). The butt and pistol grip were made of polymer plastic. The replica body and the RIS rail assembly have been anodized, which guarantees a high degree of protection of the replica against corrosion. Painting the replica itself was done by powdering, after sanding the surface. This provides much higher than usual resistance of the applied paint to abrasion. The body has USMC markings.

The replica uses a quick spring change system, so-called Enter & Convert ™. This allows you to quickly and efficiently adapt the replica's power to the conditions expected in the field of play without having to have access to a workshop or a number of specialized tools - after removing the gearbox from the replica's body, the spring replacement process takes literally a few seconds.

The advantages of the Enter & Convert ™ system are difficult to overestimate. In the light of the tendency throughout Europe to apply legal restrictions on the muzzle velocity of the replica and arrangements existing within the environments themselves, this system guarantees the user considerable possibilities and a lot of freedom. The Enter & Convert ™ system allows you to replace the main spring with minimal time, and thus, adapt the replica's muzzle velocity to the gameplay area so as to guarantee a perfect compromise between fire efficiency and your own and other players' safety.

The replica has been fully adapted to cooperate with LiPo and LiFe batteries. Due to the base initial muzzle velocity of ~ 410 FPS guaranteed by the factory-fitted main spring, the replica is perfectly suited to operate on a medium range. The set also includes an M90 spring, which allows you to reduce the initial speed to ~ 310 FPS, thus making the replica perfectly adapted to operate on a short distance or inside buildings.

Reinforced at the cylinder head, the gearbox hides a steel spring guide that is part of the Enter & Convert ™ system and steel gears mounted on 8mm ball bearings and washers. The system is secured with four anti-return latches. The light, made of polycarbonate plastic piston was equipped with a steel tooth to increase its strength. A type 2 cylinder and steel chopper were also used, as well as a metal hop-up chamber.

The Upgraded version has a number of new, reinforced parts such as:

- a set of reinforced steel gears
- steel spring guide
- lightweight polymer piston
- aluminum, sealed piston head
- metal cylinder head
- sealed metal nozzle

The replica is equipped with a 22 mm RIS rail, a set of MLOK front rails and an adjustable stock. Flip-up sights are fitted on the upper RIS rail, but they can be freely replaced by any optoelectronic sights device. Thanks to the extendable butt with non-slip texture, it is possible to adjust the length of the replica to the construction and preferences of the shooter. The flash hider is mounted on a 14-mm left-hand thread, which allows it to be connected in its place.

To increase the realism of the game, the replica was also equipped with a working bolt lock release.

The replica kit also includes a hi-cap polymer magazine that holds 300 BBs.
