Perun HPA Trigger Board V3

Perun HPA Trigger Board V3 – Advanced Magnetic & Optical Trigger Board for HPA Engines in V3 Gearboxes

Upgrade your AK-style HPA airsoft replica with the Perun HPA Trigger Board V3, a reliable electronic trigger board that replaces fragile mechanical contacts in Tokyo Marui standard V3 gearboxes. Equipped with magnetic sensors for the trigger and calibratable optical sensors for the selector (including SAFE position detection), this board eliminates wear-prone parts, ensures flawless compatibility across mixed-brand HPA setups, and adds powerful programmability while keeping your existing FCU intact.

Key Features for HPA V3 Performance

• Electronic Safety — Reliable safe mode thanks to selector sensor calibration.
• Adaptive Trigger Control — 8 sensitivity levels for both 1st and 2nd stage, adjustable from ultra-short hair-trigger to long stock-like pull. Works with almost any trigger (including stock) without modifications — even in the field.
• Programmable Firing Modes — Independently set for each selector position: SEMI ONLY, BINARY (fire on pull and release), SEMI-AUTO, SEMI-BURST, BURST-AUTO.
• DMR Mode — Enforces minimum shot intervals (0.25s to 3s) for field compliance or added realism.
• Rate of Fire Reduction — Lower ROF while keeping the first shot crisp.
• Diagnostic System — Constant monitoring with immediate alerts via multicolour LED for any issues.
• Programming — Quick on-the-field setup using selector + trigger sequences with clear multicolour LED feedback. No apps or computers required.

It pairs perfectly with the Perun Clicker V3 for realistic mechanical break and adjustable trigger feel.
