Perun V2 HPA Trigger Board – Semi-Only
The Perun V2 HPA Trigger Board (Semi-Only) is a drop-in electronic trigger interface for HPA engine conversions in V2 gearbox bodies (M4, G36, P90, SCAR, and other V2-platform AEGs). It replaces the standard trigger contacts and interfaces directly with the HPA engine solenoid — and critically, in the Semi-Only variant, it restricts the HPA engine to single-shot semi-automatic fire only, with no option to switch to full-auto.
UK woodland and outdoor airsoft sites typically prohibit HPA full-auto fire. The Semi-Only Perun V2 board provides a hardware-level restriction that ensures compliance — there is no mode switch to accidentally leave on full-auto. For HPA players running V2 platform builds on UK sites where auto is prohibited, the Semi-Only trigger board is the correct compliance solution.
