The INFERNO Gen 2 is the culmination of a great deal of work to take the next step forward in the development of HPA technology.
Over the past couple years since we launched the SMP, multiple other companies saw the value of this type of technology and have attempted to replicate its performance. The INFERNO Gen 2 HPA Engine once again leaves everyone far behind.

What's the difference between the INFERNO Gen 2 and INFERNO XTS?
The XTS fine-tunes every stage of the shot cycle. Its “extended stroke” system improves hop-up air seal, enhances feeding forgiveness, and increases separation between loading and firing movements to help stabilize each BB for tighter groupings and more consistent shots. A newly engineered valve housing optimizes internal airflow, reduces air waste, and improves dwell tuning tolerance—making precise tuning more accessible in a wider range of setups. The new recoil out port is compatible with the QUAKE MTW Recoil Stock for enhanced realism. (MTW Only)
An upgrade kit is simply an HPA engine without the solenoid. This saves you money by allowing you to move the solenoid from one engine to the other.
Is the INFERNO HPA Engine an open-bolt or closed-bolt system?
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.
