Have you ever dreamed of Polarizing your MP5, G3 or SCAR? With the introduction of the GEN3, now you can! At first glance the GEN3 FEV2 looks very much like the GEN2 and, for the most part, the two are quite similar. However, unlike its predecessor, the FEV2 GEN3 is no longer just for the M4/M16 series rifle. We applied the same concept used with our Version 3 Fusion Engine™ so that it is now able to interface with the selector plate and related components of your existing AEG’s gearbox. This makes it possible to adapt the engine for use in multiple rifle models which share the Version 2 gearbox without any major modification.
