AirsoftJunkiez are taking pre-orders of the new Wolverine Airsoft Hydra and if you want one, you'll need to select the type of AEG you'll use the Hydra for as it's not a one-size fits all HPA solution for AEGs. It will be available for M4, G&G M14, Version 3 Gearbox, M249, and a Blue-Tooth FCU option. Prices start at US$399 to US$450.00.
