Mosfet reliability and failure modes
 

How are today's off the shelf airosft mosfets in terms of reliability and failure mode?

The first and last time I tried using a mosfet a couple of years ago, it fried after less than a couple dozen shots over the course of two days. It failed closed, so the aeg wouldn't stop firing on full auto until I unplugged the battery. Freaked out my wife too.

I'm thinking about trying a mosfet again, but don't want it to fail and get stuck on full auto. Especially if using a Lipo in a sealed up buffer tube that's cumbersome to get to.

don't buy a cheap mosfet unit. I swear by extreme-fire.com products because of Terry's overwhelmingly good service and track record. He has a very low failure rate and his units are very well built.

if you really dont want it to fail, get an extreme-fire.

there are also plenty of homemade fets from reputable makers on ASM.

Speaking of ExtremeFire mosfet. Can you disable the AB on the computerized FETs?
Which one would you recommend for ROF control without AB.

Look for a hamster fet on ASM, apparently they are amazing and I have one on the way.

The gate ones stealth has on airsoftstore.ca ok too

The cheetah 2N with triggermaster software let's you turn AB on and off, and let's you control the ROF as well. I have one and it was a great investment. Any problems, and terry usually replies to you in about 24 hours.

I've been using my home-made 3034 mosfet for over 3 years now. Still works fine.

Gate merf 3.2. Nuff said. All the features you can shake a stick at round 60 bucks.

This one's nearly perfect, except I want the ability to turn AB on and off, and I'm stuck with deans (not a con, but I can't try other things).

I have installed 4 MERF 3.2s on 4 different rifles and have yet to see one fail. I run them on 2 of my own rifles, not able to turn off AB sucks but the other features make up for it.

+1 for the Gate fet's from airsoftstore. Never had one fail. Not a huge fan of the Xtreme fire fets as I always worry about the wires falling out (which they do often).

No matter what anyone says or builds Terry's track record can't be beat. Extreme-fire all the way.
