Specna Arms SA-F20 FLEX ETU

We are pleased to present to you the Specna Arms SA-F20-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 being made of reinforced nylon which allows for a reduction in weight, making it perfect for dynamic CQB games. Additionally, the nylon fiber reinforcement 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 features a factory-installed SA ETU 2 circuit, which translates to the ability to set the following:
-Sequential fire mode - from 1 to 5 shots in automatic mode
-Binary trigger
-Trigger sensitivity (3 levels of settings)
Additionally, the SA ETU 2 protects the motor from current overloads and has the ability to alarm at too high or low battery voltage levels.
The circuit has a built-in activity control mode; after an hour of inactivity, the circuit will shut off and restarting will require reconnecting the battery to the replica.

We recommend using Li-Po batteries

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