Specna Arms SA-F21 FLEX™ ETU™ Complete Package

We are pleased to introduce you to the Specna Arms SA-F21- FLEX™ replica. The attractive price combined with the quick spring change system and high-quality materials make this series particularly appealing to beginner airsoft players and beyond.

The replica has been very well constructed, with the body made of reinforced nylon which allows for a reduction in weight, making it perfect for dynamic CQB games. Additionally, the nylon fiber armor makes the construction more durable than other polymer constructions.

The replica uses a quick spring change system. This allows for quick and efficient adjustment of the replica's power to the expected field conditions.
The replica has a factory-installed SA ETU 2 circuit, which allows for setting the following features:
-Sequential firing mode - from 1 to 5 balls in automatic mode
-Binary trigger
-Trigger sensitivity (3 levels of settings)
Furthermore, the SA ETU 2 protects the motor from current overload and has the ability to alarm in case of too high or too 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.

We recommend using Li-Po batteries.

Internally, the replica features a V2 Gearbox version, with a built-in quick spring change system. The Hop-Up system adjustment is done with a rotary unit. Inside, you will also find steel gears and 8mm diameter bearings.

The package includes the replica, 2 mid cap magazines, battery, battery charger, and 90m/s spring.
