Just like the other series, Specna Arms® FLEX line is equipped with a quick spring change system. There is no need to take the gearbox out of the airsoft gun in order to exchange the spring or adjust the muzzle velocity to the required value. All you have to do is to disassemble the buffer tube by unscrewing just one screw, spin off the pin with the spring guide and exchange the spring.

Step 1
Use a screwdriver to remove the screw holding together the stockpipe and the receiver; remove the stockpipe.

Step 2
Use a screwdriver to gently push the spring guide forward. Rotate the spring guide by 45 degrees until you feel the spring's tension.

Step 3
Pull the spring guide and spring out of the gearbox.
The whole operation takes about one minute and requires only a screwdriver.
ONLY 45 SECONDS TO CHANGE SPRING
Specna Arms FLEX is a response to the constantly changing needs of airsoft players. It is a line of the lightest replicas, perfect for dynamic CQB games.
The main features of the series are light, polymer handguards, which increase the possibilities of quick usage of the replica or lightning-fast aiming. In combination with a rotary HU chamber, a precision barrel, a reinforced gearbox, and the ESA system Specna Arms FLEX are ideal Plug&Play replicas. Models from this line are also very good as bases for further modifications to increase power or rate of fire. Specna Arms FLEX is designed to meet the evolving demands of airsoft players who prioritize speed, agility, and reliability in fast-paced environments like CQB. Built around lightweight polymer handguards, this series enhances handling and maneuverability, allowing for rapid target acquisition and quick transitions between positions with minimal effort. Each replica is equipped with high-performance components such as a rotary HU chamber, a precision inner barrel, a reinforced gearbox, and the ESA system, making them reliable Plug&Play platforms right out of the box. These features not only ensure consistent performance under stress but also provide a solid foundation for future upgrades, whether you're looking to increase rate of fire or improve range and accuracy. Just as optimized gear contributes to confidence and effectiveness on the field, personal well-being can also benefit from informed choices—such as understanding Tadalafil as part of a holistic approach to intimacy, where physical health, emotional connection, and medical guidance work together to support a fulfilling lifestyle.
