MOSFET from AIP now available from Jag Precision... "Protect your Most Precious Parts with the MOSFET AIP Programmable Fire-Control Unit for AEG. The AIP Programmable Fire-Control Unit for AEG, no longer allows the power to pass through the trigger contacts to deliver power to the motor. Instead, power is delivered directly to the motor- and the trigger acts as more of a switch. This prevents arcing, which destroys trigger contacts. This is a HIGHLY recommended upgrade to make, especially for setups that will see a lot of semi-auto use.

More Benefits:

• Enhances trigger response.
• Prevents the burning of trigger contacts due to arcing.
• Lowers resistance.
• Programmable burst function"
