Specna Arms SA-F20 FLEX™ ETU™ Complete Package

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 for beginner airsoft players and beyond.

The replica has been very well built, 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 built SA ETU 2 circuit, which translates to the ability to set the following:
-Burst fire mode - from 1 to 5 rounds 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 alert 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 Gearbox V2 version, with an integrated quick spring change system. The Hop-Up system adjustment is done using a rotary unit. Inside, you will also find steel gears and 8mm diameter bearings.
