Storm HP-R HPA System for V2/M4

The Storm HP-R HPA System is a compact electro-pneumatic drop-in unit built for Version 2 rear-wired gearboxes, delivering consistent FPS and ultra-responsive trigger performance. Its adjustable nozzle ensures precise BB feeding, while the integrated digital FCU provides full control over firing modes and tuning parameters.

Engineered for competitive airsoft, it replaces standard AEG internals with a regulated HPA solution — enabling tighter shot groupings and faster cycling due to its solenoid-powered 11.1V LiPo operation.

Features:

• Precision-engineered for V2 rear-wired gearboxes: Ensures drop-in compatibility with widely-used rifle configurations.
• Adjustable nozzle with shim set: Guarantees accurate BB feeding and reliable cycling under high rates of fire.
• Digital FCU with integrated screen: Allows real-time configuration, diagnostics, and performance monitoring.
• Powered by 11.1V LiPo battery (not included): Optimised for high-output air control and consistent solenoid operation.
• Minimal FPS deviation: Enhances chrono performance, improving compliance and consistency in regulated environments.
• Fast trigger response: Critical for competitive and speedsoft playstyles where milliseconds make the difference.
• Complete install-ready kit: Includes trigger plate components, FCU cable, wiring harness, and nozzle shims for experienced installation.
