The GEN 2 Inferno 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 Gen2 once again leaves everyone far behind.

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%.

Can I upgrade my SMP/Inferno/HYDRA to a Gen 2 Inferno?

Yes! We will be offering upgrade kits which include the GEN2 Inferno body along with a filtered grip line. Simply swap the valve and electronics over from the original system and you are ready to rock!

But wait what about HYDRA?

We have recently release a GEN 2 HYDRA as well. It uses the same technology as the GEN 2 INFERNO and is adapted for offset nozzles.

Does this mean you won’t support Gen1 Inferno/HYDRA?

We do our best to always support our products even if they are discontinued. Nothing to worry about. 🙂

So with the independent nozzle and poppet is the turning more complicated?

Not at all. Because the system still is operated by the single solenoid valve direct fired design, it features the same ultra simple tuning our SMP products are known for!

Does this mean I can just drop it in and go with no extra tuning to the hop up etc?

Yes! The system performs extremely well with most stock hop up configurations. The only think you will want to check is that your alignment is right. While the Gen2 is less sensitive to alignment than single moving part systems, it will still play a role in the overall performance of the gun.

Beautiful. We pulled off consistent measured 320′ shots out of the 300mm mk18 barrel. No one could believe what they saw with their own eyes.

It’s known as the mouse fart rifle at Insane because it’s that quiet. No one hears it shoot until they feel it
