SA-F02 FLEX ™ M4 Carbine AEG (Half-Tan)

SA-F02 FLEX ™ M4 Carbine AEG (Half-Tan)

Specna Arms presents the line of replicas - FLEX ™. The attractive price combined with the innovative spring replacement system and high-quality materials make this series particularly attractive for airsoft beginners.

The body, the Free Float front, guides with an enlarged SF stock and a pistol grip are made of a polymer reinforced with nylon fiber. The barrel, the flame damper, the enlarged reloading handle and manipulators are made of aluminum and ZnAl alloy. On the other hand, all the screws, pins, the case ejection window and the dummy bolt are made of steel. There are markings and serial number on the body.

The replica has been fitted very well, the user will not provide any play between the lower and upper body parts. The use of the body and the front made of light material allowed to reduce the weight, which makes it a perfect replica for dynamic CQB games. Moreover, the nylon fiber reinforcement makes the structure more durable than other polymer structures.

The replica uses the ESA ™ quick spring change system. This allows for quick and efficient adaptation 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 is fully compatible with LiPo and LiFe batteries. Thanks to the basic initial muzzle velocity of ~ 380 FPS guaranteed by the factory-installed main spring, the replica is perfect for medium-range operations. The set also includes an M90 type spring, which allows to reduce the initial speed to ~ 300 FPS, thus making the replica perfectly suited for short-range operations or inside buildings.
