🎯 Semi-only, by design. The V2 Lightning Semi Only is permanently locked to Safe–Semi–Semi fire modes. There is no full-auto capability — this is the correct MOSFET for DMR builds and semi-only field compliance. Rear wired only.

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

🔧 Titan Forge Airsoft tip: The Semi Only version is the right choice if your site requires a locked semi-only MOSFET as proof of compliance, or if you’re building a dedicated DMR that will never run on a general skirmish field. If you want the option to run both a skirmish and a DMR build from the same rifle, you’re better off with the full V2 Lightning and using DMR mode instead. Not sure which suits your setup?
