Compatibility & Upgrades

This gearbox fits standard Tokyo Marui and Jing Gong P90 gearbox cavities. Before installation, we recommend sourcing a replacement spring suited to your site’s FPS limit (typically 350–380 FPS for UK skirmish). Pair with compatible motor and internal wear components for optimal longevity.

UK Legal & Site Notes

The high stock FPS requires tuning before use—always check your site’s chronograph limits. Once spring-matched to site rules, this gearbox provides reliable semi and full-auto performance. Internal upgrades are permitted under UK VCRA guidelines so long as the assembled AEG meets your site’s energy ceiling.
