The Wolverine Airsoft INFERNO: Gen. 1 is an update to our original SMP (single moving part) design. With only one moving part (the nozzle) in the entire system, the Inferno is the simplest and most efficient HPA engine on the market. Convert virtually any AEG airsoft gun into an HPA monster with the Inferno. It is compatible with all of our electronics (Spartan, Premium FCU, and Bluetooth FCU for Android). It is completely modular with Hydra, meaning you can start with our most basic option (Spartan Edition) and upgrade when you need to without buying an entirely new system. HPA is on the rise and Wolverine Airsoft is truly propelling the market forward. If you are ready to make the jump, hop on board with us, because we are leading the way.
