Both the receiver and the front grip in the Keymod system, in each of the models is made of a composite called Carbontech. It is characterized by high durability and light weight.

Among parts used in these replicas are the BCM type pistol grip and stock, and thanks to an appropriate design, access to the motor does not require the use of any tools. Folded, polymer sights will provide quick access to them in the event of optics failure, and an aluminum barrel guide made on CNC machines will ensure durability at an appropriate level.

The internal parts include a reinforced gearbox with a quick spring change system, adapted to work with LiPo batteries. Changing the spring does not require removing it from the receiver, thanks to which changing the muzzle velocity can be made quickly. It also has a separate space inside for a MOSFET system and the manufacturer's electronic trigger, which is sold separately. The heart of the replica is equipped with an anodized cylinder and steel gears with a delayer, set in 8 mm self-lubricating bearings.

The barrel, with an inner diameter of 6.01 mm, is connected to a rotary type hop-up chamber, thanks to which the system's adjustment will be smoother, more precise and it will retain its settings better.

From other parts worth mentioning are the two-sided steel sling attachment points and a working dummy bolt carrier and ejector port cover. Three accessory rails made in Picatinny standard are also sold with each replica and intended for mounting on the front grip. Thanks to them, the owners won't have problems with installation of accessories compatible with RIS rails.
