The INFERNO Gen 2 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%. 

Our kits include choice of our Spartan Electronics board or Gen 2 Premium FCU and everything you need to install the INFERNO Gen 2 in your gun platform.
