Perun V3 HPA Trigger Board – Semi-Only
The Perun V3 HPA Trigger Board (Semi-Only) is the V3 gearbox equivalent of the Perun HPA trigger board — a drop-in electronic trigger interface for HPA engine conversions in V3 gearbox bodies (AK-pattern AEGs, MP5, G3, and other V3-platform designs). In the Semi-Only variant, it restricts the HPA engine to semi-automatic fire only with no full-auto mode option — a hardware-level site compliance solution for UK outdoor and woodland fields where HPA auto is prohibited.
V3 gearbox bodies require a different trigger interface geometry to V2; this is the correct board for AK and V3 platform HPA builds. For HPA players running AK-pattern or other V3-body platforms on UK sites, the Semi-Only V3 trigger board ensures correct gearbox fitment and site-compliant fire mode restriction.
