The 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, and more into an HPA monster with the HYDRA Gen 2.

Each kit contains our Gen 2 Premium FCU and everything you need to install in the HYDRA in your gun platform.
