The replica has been very well customized the user will not experience any play between the lower and upper part of the body.

The use of a body and front made of reinforced nylon allowed a reduction in weight, which makes it perfect as a replica for dynamic CQB games. In addition, the nylon fiber reinforcement makes the construction more durable than other polymer constructions.

The replica has a factory-installed SA ETU that allows the following settings:
-Series mode - from 1 to 5 shots in automatic mode
-Binary trigger
-trigger sensitivity (3 settings)
In addition, the SA ETU protects the motor against current overload and has the ability to sound an alarm if the battery voltage is too high or too low.
The circuit has a built-in activity control mode; after one hour of inactivity, the circuit shuts down and restarting requires reconnecting the battery to the replica.
