  • Active Braking Technology
  • Includes additional kit of Deans-T connectors, single signal wire, and double signal wire for trigger contacts
  • Can Handle 7.2v to 14.4v Batteries
  • Weather Resistant
  • 1 Year Limited Warranty
  • Wiring, Deans Plugs and Heat Shrink Tubing included

Do you want to achieve a higher rate of fire and faster trigger response? Are you planning a power upgrade of your rifle? In that case, you need a MOSFET.It targets the energy from the battery directly to the motor, bypassing the mechanical trigger contacts. As a result, you will gain higher rate of fire of the rifle and a faster trigger response, and the contacts will be protected against burn out.

Active Brake:
Do you care about realism? Would you like to increase the life of the gearbox? Does your rifle have such high rate of fire that you are not able to make a single shot? Active brake will sort things out.In SEMI Mode, the brake will not allow for compressing the piston after a shot. The piston will stop in front position which eliminates unnecessary stresses, increasing the service life of Gearbox and its parts. It is very important, especially with an AEG power upgrade.After releasing the trigger, the rifle immediately stops shooting. Thus, you will gain more realism and, additionally, wont lose your precious ammunition.

Electronic Fuse:
A new MOSFET will never let you down on the battlefield. It is totally protected against overheating and short-circuits of the electrical system. In case of the rifle becoming jammed, it will protect the motor and the battery against any damage.

Digital Interface:
It provides full compatibility with micro-switches. It is fully resistant to contact bounce. You gain a bigger ROF, faster trigger response and your MOSFET becomes less heated.

3rd Generation Mosfet:
Usage of most modern transistors and microcontroller enabled us to create the smallest and most reliable MOSFET in the market.WE GUARANTEE that the MOSFET will work with the strongest AEG replicas. If you damage the MOSFET, we will reimburse you for 100% of your costs or replace it with a new one at our expense.

Dimensions: 9mm x 19mm x 42mm
Compatibility: For Most Airsoft AEG Rifles. Installation required, professional installation recommended. Not compatible with AEGs with Micro Switches

"Set one of these up wired straight to a contact for my A&K M249. Decided to cheap out and not go with a ROF control mosfet.

However, this does just fine, because it allows me to use a 11.1v Titan and not burn up my gun.

Has dual and single signal wire(Dual is best for LMG)
Can handle an 11.1v very easily(Runs my 48 amp 11.1v like it is nothing)
Super easy to install as long as you know how to solder
Comes with everything you need mounting and hardware wise

Can't turn on or off active braking(My case it doesn't matter)

Just a super simple mosfet. Definitely recommend.

"I love how simple this is to install. I swapped my Krytac mosfet out to this mainly for active braking (krytac was over cycling) it feels much more consistent and more crisp on semi now. I installed with two signal wires to the trigger. Very easy if you know how to solder.

"Fantastic MOSFETs. I have two so far for my loaner pool. They include a signal wire pair to attach directly to your trigger contacts. The MOSFET does support traditional MOSFET wiring as well, where it includes a single signal wire and your positive wiring can be soldered to the other trigger contact on its way to the motor. You don't have to rewire anything if there is a problem with the MOSFET since it's all plug and play after the initial wiring.

This MOSFET comes with active breaking. This helped very much with the two of my builds that are 32RPS. On semi, they can double fire. Active breaking can wear out your motor brushes, but they will typically need to be replaced after every other cleaning of the gearbox. Motor brushes are also cheap.

This MOSFET also comes with debouncing. One of the builds uses a microswitch. A microswitch, as it closes from a trigger pull, can bounce and send multiple signals instead of one. A capacitor on the MOSFET filters this out into one signal.

Overall, these are my go to when not installing a TITAN or Spectre. They are cheap, reliable, and easy to replace if for some reason something was going to happen to it.
