Specna Arms SA-F21 FLEX? ETU? airsoft rifle Black

The replica has been very well-fitted the user will not experience any play between the lower and upper parts of the body. The use of a body and front made of reinforced nylon allowed for a reduction in weight, making it perfect as a replica for dynamic CQB games. What is more, the nylon fibre reinforcement makes the construction more durable than other polymer constructions.

The replica uses the quick spring replacement system. This allows for quick and efficient adjustment of the replica's power to the conditions expected on the battlefield without the need to have access to a workshop or a number of specialised tools.
The replica has a factory-built SA ETU 2 circuit, which translates into the ability to set the following:
-Series firing mode - from 1 to 5 shots in auto mode
-Binary trigger
-Trigger sensitivity (3 levels of settings)
Additionally, the SA ETU 2 circuit protects the motor from current overloads and has the ability to alarm on too high or low battery voltage.
The circuit has a built-in activity control mode; after an hour of inactivity, the circuit will shut down and restarting will require reconnecting the battery to the replica.
