JeffTron AEP MOSFET (JST Connector)

AEP MOSFET with JST Connector

AEP MOSFET by JeffTron is designed to significantly improve the performance of your electric AEP pistol. It increases RoF, improves energy efficiency, and protects trigger contacts from burnouts. Thanks to its pre-wired JST-SYR connector, installation is fast and simple, but requires soldering. The unit features a Micro MOSFET II and is coated for moisture resistance. Compatible with most popular AEP models without internal modifications.
