Quick Summary
The Perun V2 Lightning MOSFET is a rear wired MOSFET for an airsoft AEG with a Tokyo Marui V2 gearbox design. It replaces mechanical contacts and is described as working with most V2 gearboxes in Tokyo Marui standard. The rear wired Deans connector configuration is a key choice point, and some non-standard V2 gearboxes may need modification.
The main appeal is the programmable control it adds, including trigger modes, fire modes, DMR mode, low battery alert, active braking, diagnostic LEDs and dual sector gear support. Because this is a gearbox upgrade, the fit, wiring layout and installation approach matter as much as the feature list.
Key Details
| Detail | Verified information and buyer relevance |
|---|---|
| Product type | MOSFET for an airsoft AEG, intended as a gearbox upgrade. |
| Gearbox design | Tokyo Marui V2 gearbox design. Check this against the replica gearbox before choosing. |

| Connector | Deans connector. Confirm this matches the battery and electrical setup. |
| Programmable firing modes | Safe, semi, burst or auto firing can be selected on both selector positions. |
| Trigger modes | Includes sensitivity levels, 2-stage trigger mode, binary trigger mode and precocking. |
| Other functions | Active braking, low battery voltage alarm, diagnostic system with LED indicators and dual sector gear support. |
| Installation note | Professional installation is recommended for all gearbox upgrades. |
What to Compare Before Buying
- Gearbox compatibility: This unit is made for a Tokyo Marui V2 gearbox design, so check that the replica uses the same general layout.
- Wiring layout: It is rear wired, so the internal layout of the build needs to suit that arrangement.
- Connector type: The connector is Deans, so confirm the battery and wiring plan match.
- Firing behaviour: Compare the available fire modes and trigger modes with the way you want the AEG to operate.
- Installation approach: A gearbox upgrade like this should be checked against the builder’s skill level and fitting requirements.
What Else You May Need
The rear wired Deans connector setup means the rest of the build needs to suit that connector type. If the gearbox is not a standard V2 layout, modification may be required.
How It Works
The MOSFET replaces mechanical contacts and adds programmable control to the AEG. It can change firing behaviour, adjust trigger response, reduce rate of fire in certain modes and provide battery and diagnostic feedback through the built-in alarm and LED indicators.
Common Buyer Questions
Does it work with any V2 gearbox?
It is described as suitable for most V2 gearboxes in Tokyo Marui standard, but non-standard versions may need modification.
What does the rear wired setup mean?
The wiring is arranged to the rear of the unit, so the host build needs to suit that layout.
Is installation straightforward?
It is a gearbox upgrade and professional installation is recommended.
Before You Decide
Confirm the gearbox is a Tokyo Marui V2 style, check that rear wiring suits the build, and make sure the Deans connector matches your setup. If the gearbox is non-standard, plan for possible modification and professional installation.
