Storm HP-R HPA System

Elite Electro-Pneumatic Performance

For players who refuse to settle for the mechanical limitations of a traditional AEG, High-Pressure Air (HPA) is the ultimate upgrade path. The Storm HP-R HPA System replaces your gearbox's conventional gears, motor, and piston with a highly advanced pneumatic engine. Because it operates on regulated air rather than mechanical tension, it delivers a ferociously fast trigger response that mechanical setups simply cannot match. This allows for rapid follow-up shots and unparalleled performance in high-pressure CQB or tournament environments where milliseconds make all the difference.

Integrated Digital FCU & Easy Tuning

Tuning your HPA setup has never been easier. The Storm HP-R comes equipped with an advanced digital Fire Control Unit (FCU) featuring an integrated display screen. This allows you to effortlessly monitor diagnostics and dial in your precise performance parameters directly from the board, without needing complex trigger pull programming or external Bluetooth modules. You have complete control over your rifle's firing modes, dwell time, and rate of fire, allowing you to tailor your loadout exactly to the rules and limits of your local skirmish site.

V2 Gearbox Drop-In Compatibility

Engineered for the industry's most popular platform, the HP-R is a direct drop-in fit for Version 2 rear-wired gearboxes (standard M4/AR15 style replicas). This complete, install-ready kit includes the essential trigger plate components, wiring harness, and FCU cables, allowing experienced techs and confident players to seamlessly convert their favourite AEG body into a top-tier, custom HPA monster.

Flawless Feeding & Consistency

A common issue with aftermarket HPA conversions is nozzle alignment and BB feeding. The Storm HP-R solves this completely with a highly precise adjustable nozzle and included shim set. This guarantees that the engine aligns perfectly with your hop-up chamber, ensuring accurate BB feeding even at blistering rates of fire. Furthermore, the robust electro-pneumatic design minimizes FPS deviation, resulting in incredibly tight shot groupings, improved chrono compliance, and laser-like accuracy downrange.
