The Wolverine Airsoft HYDRA: Gen. 2 utilizes our proprietary HYBRID open/closed bolt technology from the Inferno GEN 2. It functions and performs like our Inferno GEN 2, but with offset nozzles. The Hydra was the first out-of-the-box drop-in HPA engine for guns with offset nozzles. Convert guns like the M14, P90, Tavor, and more into an HPA monster with the Hydra GEN 2. We have also added a front bushing plate for improved nozzle stability. Now your unique guns can shoot with the accuracy and consistency as our Inferno GEN 2 in M4 and other common style platforms. 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.

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 tuning 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 thing 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 itChris Cosentino, Parafrog Airsoft, Knoxville, TN
