If you want a break from standard M4 HPA builds, then give this Wolverine Airsoft V3 Hydra unit a shot in your AK47. The new Hydra units allow for complete customization of their gun. If you have multiple platforms, you can simply change out the front of the Hydra unit, for a different nozzle style, and drop it in a new gun. With the addition of the optional Bluetooth FCU, you can fully tune your gun, without having to physically change any controls, via your smart phone. The word revolutionary gets thrown out a lot, but in this case, there is no denying that this is truly revolutionary. The FCU is fully programmable by two simple dials. This complete unit includes everything you need to get started: FCU, battery, trigger board, wire harness, and the manual.
