"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.

Pros:
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

Cons:
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.

"Well I've been building guns for at least 10 years now and just installed a GATE NanoAAB, first GATE product I've used and I have to say, Nice. I installed replacing the existing wires and re-connecting the dual sensor wires provided with the mosfet unit to the two trigger contacts- the full install method. Very easy for a reasonably experienced tech type. Took about 1 hour. I ran the 2 small sensor wires and the 2 larger black and red power wires together through the back of the gearbox into the buffer tube for rear wiring in a G&P M4. A little snug getting everything through the channels but it all fit and hooked up to an 11.1v 1200mah lipo in the buffer tube. Haven't game tested yet but fired a few rounds in the shop and the thing has definitely increased the ROF and stops on a dime with piston all the way forward every shot in semi. Does what it advertises and I'm pleasantly impressed. If you're after a small unit that will save your trigger contacts from frying with time, stops instantly after a full cycle without half cocking the spring in semi, and increases ROF, but you're not interested in programming or fancy shooting modes...get this one. And leave the anti-reversal latch in, btw.

"This works great, I have them in 3 of my guns, they fit in just about any buffer tube, or battery compartment. I wish the instructions were a littler clearer but there were some videos and other info how-to guides that I was able to find. The active breaking helps when running a high RPS motor setup. A good investment if you value your guns internals and motor and want to run 11.1v lipos.

"I bought this back in November and have defiantly put it through it's paces. It's a fantastic MOSFET unit! Keeps my m4 from over spinning with an m90 in it and help to increase the overall trigger response. I highly recomend this unit and any mosfets made by GATE!

"bought one as an emergency replacement and it is now my first recommendation to people looking to install a MOSFET. install was so simple that i was almost sure i had done something incorrectly but it really was just easy. it lacks the programmability of the more pricey gate fets but no additional soldering needs tk be done to upgrade to one later which is pretty cool.

"I have three of these and they all work exactly as they say. The trigger response with these is great. It also handles big batteries nicely. It is worth getting.
