The Perun AUG Smart Mosfet transforms the trigger response and reliability of your Tokyo Marui standard AUG replica. By combining magnetic sensor technology with optical gear detection, Perun has engineered a MOSFET that addresses common friction points in the AUG platform whilst maintaining the precision you need for skirmish and milsim use.
Key Features
- Magnetic trigger sensors – eliminate the mechanical trigger bar for a smoother, more responsive pull
- Optical sector gear detection – ensures reliable and consistent single-fire performance
- Tokyo Marui AUG compatible – designed specifically for TM standard AUG replicas
- Enhanced reliability – optical detection reduces misfires and improves trigger response consistency
- Compact installation – fits within standard AUG mechanical contact points
Real-World Use Cases
If you’re running a Tokyo Marui AUG and want tighter trigger control for precision target work or consistent semi-auto engagement on the skirmish field, the Perun Smart Mosfet is a straightforward upgrade. Players who’ve found the stock AUG trigger pull unsatisfying will appreciate the smoothness gain without needing to replace the entire gearbox. Milsim players benefit from reliable single-fire function during long scenarios.

Compatibility & Upgrades
This MOSFET is engineered for Tokyo Marui standard AUG platforms only. Installation involves removing the standard mechanical trigger bar and integrating the magnetic sensor assembly. No gearbox replacement is required. Pair with a quality battery and configure your firing modes via the Perun app or control unit (if applicable) for maximum customisation.
UK Legal & Site Notes
The Perun AUG Smart Mosfet is a pre-engagement and trigger-control electronic unit. Installation does not alter the replica’s FPS output or legal classification. Ensure you check your skirmish site’s rules on MOSFET use and pre-engagement features; most UK sites permit them freely. Always chrono your AUG before play to confirm it remains within your site’s power limits (typically 328 FPS with 0.20g BBs for AEGs).
