"The Cyma assault rifle AK Magpul is an airsoft copy of the combat AKM, put into service in the USSR in 1959, in the Magpul body kit. The kit with the drive includes a bunker magazine, battery, charger, a key for adjusting the front sight and a ramrod. The product is made of Nylon (stock, magazine, handguard, receiver, picatinny rail) and steel (outer barrel, fire switch).

Nylon is highly durable. It is also lighter than plastic, making it only 2.5 kg. The initial speed of the ball is 130 m/s. The airsoft gun is equipped with an M-lok handguard for attaching additional equipment (if desired, you can install an adapter to the standard picatinny rail). To install the battery, you need to snap off the receiver cover up. The retractable buttstock of the Machine Gun is made of plastic with a rubberized butt pad.

The Cyma AK Magpul is a lightweight and compact drive that is suitable for indoor or medium range combat. The ability to adjust the butt makes it easy to store and allows you to adjust in accordance with the situation and the parameters of the owner."
