The Potency® SPIRAL Complete Kit delivers a significant upgrade to airsoft gearboxes, offering smoother engagement and quieter operation. Its helical gear design optimizes power transmission, minimizing friction, vibration, and noise, while enhancing the lifespan of internal components.

Key advantages

Helical gear geometry for gentler engagement and reduced wear over time.

Direct compatibility with standard AEG gearsets, avoiding complex structural modifications.

Durable materials chosen to withstand repeated stress and ensure consistent performance.

Complete kit including dedicated tool and fastening hardware for quick, reliable installation.

User experience
After installation, the gearbox provides more gradual spin-up and softer energy release, resulting in quieter firing cycles—beneficial for stealth tactics—and less internal stress on gears, extending overall durability. During intense gameplay, the mechanism remains smooth and dependable.

Warnings and usage information (compliant with Italian GPSR regulations)

Keep out of reach of children, as small parts may pose ingestion or choking hazards.

Store in a dry environment away from heat sources and excessive humidity to preserve material integrity.

Before any intervention, ensure the battery is disconnected and no power source is attached; operate with the gearbox fully de-energized.

Follow standard disassembly and assembly procedures from the replica manufacturer; use only appropriate tools and the provided fastening hardware.

Use only batteries and components recommended by the replica’s manufacturer, adhering to specified voltages and technical requirements to avoid overloads or malfunctions.

Apply suitable lubricant for airsoft gearboxes in correct amounts; avoid excess or incompatible products that could attract debris or cause jams.

It is forbidden to tamper with or alter the original gear geometry in any way: modifications may compromise safety, reliability, and longevity, risking sudden failures or malfunctions during use.

After mounting, perform dry tests (without BBs) to verify proper alignment and absence of abnormal noises: proceed to field use only if everything is regular.

Disassemble only with proper tools and following technical guidelines from the replica’s manual or certified instructions; if in doubt, consult an experienced technician.

Carefully store any spare parts provided for future maintenance interventions.

Perform all cleaning and maintenance operations only when the replica is fully de-energized: remove batteries and magazines before any work.
