Wolverine + ICS AIRSOFT

HPA Hera.Arms M4


The Arena Custom built Hera.Arms M4 is a combination of the ICS full metal Hera.Arms body and Wolverine Gen.2 Inferno – Spartan Edition. High performance HPA Airsoft gun which operates on compressed air!


The GEN 2 Inferno features a revolutionary single solenoid, independent poppet and nozzle design that sets a new standard for a drop in kit. Particularly, it is designed to solve the “open bolt problem”. It is a hybrid design which keeps the advantages of an open bolt system: easy tuning, no first round dry fire, efficiency, etc… and adds the simplicity of easier hop up tuning that closed bolt systems have traditionally offered. In addition, it further improves the efficiency over our previous systems by an estimated 10-15%.


This will require a small 7.4v (sold separately) battery to run the engine. The Spartan edition doesn’t come with a tuning board, it includes the Spartan trigger board instead. Programming the dwell, rate of fire and switching to 3-round burst is done by the trigger in ‘programme mode’ – Programming instructions.
