Specna Arms SA-F20 FLEX? ETU? airsoft rifle Black

The replica uses fast 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.

Manufacturer's recommendation: use with Li-Po/Li-Ion batteries only
