Back in March we posted information on the then-new FLEX series from SPECNA ARMS, and we hoped that this was going to be an entry-level AEG that would be both durable and affordable for all, and now our testing is complete!

To recap on the features of these new models the F01 (short, pictured) and F02 (carbine) are designed for the new player or for those that want a backup AR AEG at a great price, and both models have an innovative quick spring change system, great performance straight out of the box and high-quality components.

The receiver, the Free Float front, the guide with the enlarged 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 aluminium 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, so there’s no loose elements or rattle between the lower and upper receiver parts. The use of a light plastic front and receiver allows for significant weight reduction, which makes it perfect for more dynamic games and CQB. The reinforcement with nylon fiber makes the AEG more durable than many polymer replicas.

Although priced to entice you still get Specna’s quick spring change system, ESA ™. This allows for quick and efficient adjustment of the AEG’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. Both models have been fully adapted to work with LiPo and LiFe batteries. Thanks to the basic muzzle velocity of ~ 375 FPS guaranteed by the factory-installed main spring, the replica is perfect for mid-range operations, but in the box you also get an M90 spring, which allows you to reduce the initial muzzle velocity to around 300fps, making both models perfectly adapted to operate at short distances or inside buildings.

Now we’ve been giving the F01 some real “hammer time” and so far, so very good! For the full lowdown you’ll have to wait a couple more weeks until Issue 139 drops, but we will say here and now that if you pick up one of these little crackers, either to get you going or to back up your primary AEG, then it’ll be money well spent!
