The GATE MERF 3.2 is a multifunctional programmable 3rd generation MOSFET.  With 10 programmable functions you are finally in complete control of your AEG. The system allows for burst fire, lossless rate of fire adjustment, LiPo and LiFe Protection, and Smart Trigger control for extra fast trigger response.  The MERF 3.2 is Plug and play compatible(some features require advanced installation), rated for up to 15 Volts and features preinstalled deans connectors for easy advanced installation with no soldering on the circuit board required.  The system settings are easily programmed with the system programming cable and 4 onboard LED's.    

Package includes:

  • Additional set of Deans-T Connectors
  • Single signal wire for trigger contacts
  • Double signal wire for trigger contacts
  • System programming button
  • 12 Month Warranty




The mosfet  bypasses the mechanical trigger contacts eliminating unnecessary resistance and Arcing. As a result you will gain a higher rate of fire, a faster trigger response, and the contacts will be protected against burn out.

Active Braking

Is your rate of fire so high that you get multiple shots in semi automatic?  Does your gearbox stop cycling with the spring partially compressed causing unwanted wear and tear on internal components?  Active Braking Stops the motor immediately after releasing the trigger preventing over cycle in Semi automatic.

Electronic Fuse

Automatically Shuts off power to your AEG should the current or temperature reach dangerous levels.

UVP Protection

LiPo batteries are very sensitive to over discharge. The MERF microprocessor constantly monitors battery voltage and cuts off power to the AEG before the battery is discharged to dangerous levels.

Digital Interface (Debouncing)

This provides full compatibility with micro-switches by preventing the negative effects of contact bounce. You gain a larger boost in ROF, a faster trigger response, and your MOSFET will be less prone to heating.

Plug & Play Compatible

You can plug the MERF 3.2 directly into your AEG with no disassembly or soldering.  

IMPORTANT: MOSFET Must be set to simple mode with the programming button prior to use. In order to prevent arcing and contact burn out advanced installation using the signal wire is necessary. 

Rate of Fire Control

Allows for lossless reduction of the rifle’s rate of fire by up to 70%.

Smart Trigger

Smart trigger control works in conjuction with the ROF Control system and allows the motor to operate at full RPM for the first shot and then reduce the rate of fire to the desired level for subsequent shots.  This allows you to control your rate of fire without sacraficing trigger response.

Burst Mode

Burst mode allows you to set the SEMI* or the AUTO funtion of the selector to 3 round burst fire.  Burst delay is fully programmable to for compatability with a wide range of battery, motor, and gearbox configurations. The processor actively monitors battery voltage and adjusts the Burst time accordingly to maintain reliable function throughout a batteries discharge cycle.

*SEMI to BURST is available in enhanced mode only
