If you’re running a DMR build or playing at a semi-only site, you need a MOSFET that’s locked in — not one you have to trust yourself not to switch to auto. The Perun V2 Lightning Semi Only solves that problem at the hardware level.
Hardwired to Safe-Semi-Semi only, this version of Perun’s brand new V2 Lightning gives DMR players and semi-only field users all the performance benefits of the full unit — optical sensors, precocking for instant trigger response, active brake to eliminate overspin between shots, and DMR mode to enforce the required intervals between shots for field compliance. The full-auto capability simply doesn’t exist. There’s nothing to accidentally switch, nothing for a marshal to question.
Like the full V2 Lightning, it replaces worn mechanical contacts with optical and magnetic sensors, supports brushed and brushless motors, runs on 7V to 17V, and programmes entirely through selector and trigger sequences — no app, no cable, no hassle.
Feature set
| Feature | Detail |
|---|---|
| Fire modes | Safe – Semi – Semi only — no full-auto capability |
| Trigger sensor | Optical — replaces mechanical contacts entirely |
| Selector sensor | Magnetic Hall-effect — unaffected by ambient light |
| Trigger sensitivity | 5 adjustable levels — field-adjustable, no modification needed |
| Precocking | Piston held compressed after each shot for instant trigger response |
| Active brake | Stops motor after each shot — prevents spring compression and overspin |
| DMR mode | Enforces intervals between semi-auto shots to meet field DMR rules |
| Rate of fire reduction | Adjustable for realistic or rule-compliant fire rates |
| Low battery alarm | Audio warning when LiPo/Li-Ion voltage drops to unsafe level |
| DSG mode | Dedicated sector gear detection mode for dual sector gear builds |
| Diagnostic system | Continuously monitors the replica — reports faults via sound and LED |
| Electronic fuse | Auto-disconnects battery on short circuit or motor blockage |
| Programming | Via selector/trigger sequences + sound & LED feedback — no app or cable needed |
