- description
Perun have built a serious reputation for making some of the best MOSFET upgrades in airsoft — and the brand new V2 Lightning is their most feature-packed V2 unit yet.
Where most MOSFETs simply replace your trigger contacts, the V2 Lightning goes much further. An optical trigger sensor and magnetic Hall-effect selector sensor replace every mechanical contact point in your gearbox — the parts that wear out, corrode, and cause misfires over time. The Hall-effect selector works via magnetic field rather than physical contact, meaning it functions perfectly in receivers with cut-outs and is completely unaffected by ambient light. The result is a gearbox that is more reliable, more responsive, and far more tuneable than anything stock.
Precocking holds the piston compressed after each shot so the next round fires the instant you pull the trigger — no lag, no delay. Binary trigger fires on both pull and release. The 2-stage trigger gives you two different fire modes across a single pull. Active brake eliminates overspin and double-shot issues at high rates of fire. Programming is done entirely through selector and trigger sequences — no app, no cable, no laptop. Change any setting in seconds, even mid-game.
Compatible with brushed and brushless motors, all gearsets including DSG, and runs on anything from 7V to 17V. Fits most AR-type builds straight out of the box.
Full feature set
| Feature | Detail |
|---|---|
| Trigger sensor | Optical — replaces mechanical contacts entirely |
| Selector sensor | Magnetic Hall-effect — unaffected by ambient light, works in cut-out receivers |
| Trigger sensitivity | 5 adjustable levels — field-adjustable, no modification needed |
| Fire modes | Independently programmable per selector position: safe, semi, burst (2–10 rounds), full-auto |
| Precocking | Piston held compressed after each shot for instant trigger response |
| 2-stage trigger | Semi–burst, semi–auto, or burst–auto across a single trigger pull |
| Binary trigger | Fires on both trigger pull and release in semi-auto mode |
| Active brake | Stops motor after each shot — prevents spring compression and overspin |
| Rate of fire reduction | Reduce auto/burst ROF for ammo conservation or realism |
| DMR mode | Enforces intervals between semi-auto shots for field compliance |
| 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 |

Compatibility & installation
The V2 Lightning comes with a proprietary selector plate that fits most AR-type replicas straight out of the box. For replicas with non-standard selector plates, the package includes a magnet with double-sided tape and a positioning tool — no permanent modification required. The selector can be calibrated after installation to ensure accurate position detection. Always refer to the official Perun V2 Lightning manual for the full compatibility list and any exceptions.
