Storm HP-R HPA Unit

Ready to drop the mechanical gears, forget worn gearboxes and experience the raw performance of high pressure air instead? STORM HP-R is developed and designed in France as a well-thought-out, streamlined drop-in solution for airsoft players who want top performance.

This conversion kit is made to be compatible with ordinary rear-wired V2 gearboxes. The kit quickly turns your standard AEG into a high-performance electro-pneumatic HPA build – without the hassle of complex installations.

Instant response and digital control (FCU)

STORM HP-R takes your game to a new level with features ordinary electric rifles cannot offer:

• Very fast trigger response: Instant shot delivery and an ultra-short trigger reset that only a true HPA system can deliver.
• Digital FCU with display: The supplied Fire Control Unit (FCU) has a clear digital screen. That makes it very easy and intuitive to fine-tune and change your settings directly on the field (on the fly).
• Adjustable nozzle: Ensures the right BB feeding and a fully tight air seal in your hop-up chamber.
• Full control over power and ROF: You can quickly fine-tune both your muzzle velocity (m/s and J) and your rate of fire (ROF), so your rifle meets the safety rules at any site.

Advanced tuning options

With the digital FCU, you get detailed control over how your rifle behaves in the field:

• Saved profiles: Create and save specific setups, so you can quickly switch profile depending on which site you play at.
• Fire modes: Independent settings for both the first and second position on your selector (e.g. semi, burst or full auto).
• Rate of fire (ROF): Adjust freely from realistic, slow milsim rates to high-speed "laser" setups.
• Technical timings: For the tech enthusiast, you can micro-adjust parameters such as Nozzle Dwell, A-ST Timeout and A-ST Pulse to get maximum air efficiency.

Power requirements and easy maintenance

This system is built to last a long time without constant fuss. To keep the mechanics lubricated, simply put a single drop of silicone oil into the air line valve every 3000 shots. It does not get easier than that!

• Power source (important): The system's internal solenoid requires an 11.1V LiPo battery with T-plug (Deans) connector (battery sold separately).
• Compatibility: Standard V2 gearboxes (rear-wired).

If you want top-level performance, a very fast trigger and a good digital interface at a price that does not break your budget, the STORM HP-R is an obvious choice for your next rifle project.
