An HPA kit designed to be accessible to all

French brand STORM has designed an HPA conversion kit to convert your Gearbox V2 AEG airsoft replicas with rear wiring. They've designed it to be quick and easy to install for players with an AEG M4 or HK replica, for example.

The digital display supplied with the FCU makes setting up the replica much easier, with a simple, uncluttered visual interface. This electro-pneumatic system also features an adjustable-length nozzle. To use the HP-R System, you'll need a LiPo 11.1v battery with T-Dean connector, to be purchased separately, to power the solenoid internally. This accessory will give you exceptional responsiveness and the ability to adjust the replica's power or rate of fire. To set up your HPA system, you can access the following items:
- PROFILE: Giving you access to the possibility of setting up two distinct profiles in the FCU
- Firing speed (ROF): Allows you to set the firing speed, measured in revolutions per second (RPS)
- SHOOTING MODE on first position: can be set to SEMI, BURST from 2 to 5 shots or BINARY trigger modes
- SHOOTING MODE on second position: can be set to FULL AUTO, SEMI, BURST from 2 to 5 shots or BINARY
- NOZZLE DWELL: Determines how long the nozzle remains in the rearward position, allowing the loader to keep up with the rate of fire
- A-ST TIMEOUT : No need to modify this parameter according to the manual
- A-ST PULSE: No need to modify this parameter either, according to the manual

This accessory is easy to maintain, as every 3000 rounds fired at maximum, you need to put a little silicone oil in the valve located on the air supply hose connected to the replica. The dematerialized user manual can be accessed via the QR code on the side of the box. This manual will give you access to all the information made available by STORM, including product specifications, an installation guide, how to use the kit and how to maintain it.

This kit is perfect for upgrading your AEG replica to HPA without being too expensive, and is much more accessible to beginners when it comes to setting parameters.
