Specna Arms proudly presents the FLEX ™ line of replicas. An affordable price combined with an innovative quick spring change system, great performance straight out of the box and high-quality components makes this series an excellent choice for both beginners and experienced airsoft players alike.   
The receiver, the Free Float front, the guide with the enlarged SF stock which houses the battery and the pistol grip are made out of nylon reinforced polymer. The barrel, the flash hider, the enlarged reloading handle and manipulators are made out of aluminum alloy and ZnAl. All of the screws, pins, the ejection flap and the dummy bolt are made out of steel. There are markings and a serial number on the receiver.
The replica has been very well-made, the user will not experience any loose elements between the lower and upper receiver parts. The use of a light plastic front and receiver allowed for significant weight reduction, which makes it perfect for dynamic CQB games. The reinforcement with nylon fiber makes the replica more durable than other polymer replicas. 
One of the replica’s features is a quick spring change system, ESA ™. This allows for quick and efficient adjustment of the replica's power to the conditions expected in the game field without the need to have access to a workshop or a number of specialized tools.
The replica has been fully adapted to work with LiPo and LiFe batteries. Thanks to the basic muzzle velocity of ~ 340 FPS guaranteed by the factory-installed main spring, the replica is perfect for middle-range operations making it the replica perfectly adapted to operate at short distances or inside buildings.
