Airsoft guns draw A LOT of current, and this project WILL backfire unless you know what you are doing. Don't think this is a quick fix.

No, I'm not bashing the MOSFET trigger, I plan to build one myself because I have the electrical knowledge to know what I am doing, but I still need to learn more about how people have used them in airsoft before I even think of starting the project.

What's going to kill a FET, especially a MOSFET, is going to be heat and/or cemf and/or inductive spike. Simply installing a $25 MOSFET without installing diode protection for that FET and without multiple FETs to share the load is a complete waste of time and money.

If you have experience in electronics, you'll know what I mean and be able to do it simply and effectively. Use no less that 2 FETs and your shunt can be placed on the same "board" as your FETs.

The way some have done it here with 1 FET and a few minutes of soldering is not the best way, that's for sure. Follow the design of a switch for a cordless drill. It does everything you could ever want for an AEG, including dynamic braking, and inductive spike shunt. The ones I've replaced in my drills have all had 2 FETs and they pass current in the same range as an AEG, but new ones for a Makita, Milwaukee, etc. can cost up to $150 each.

I couldn't agree more. Though I never thought of looking at how electric drills work, I will keep that in mind, thanks.

This all seems out of my league..... sounds like a serious research project and to tell you the truth...at this point I dont think im going to tackle it. Ill just replace my switch, and if I happen on another arc similar to what has just happened, ill look into it at that point. I love to tinker, but airsoft season is ending for me in 2 weeks...I dont plan on playing winter games, I have snowboarding to do. So I have about 5-6 months to do all this research before next season starts. I dont want to make purchases and do installs on blind faith. The mosfet (from what Ive read) sounds good, but I have some time to really get into the research in the comming months, along with other planned upgrades. Its one thing to be told its good, but I believe, like every upgrade, to learn if its right for yourself.
This sounds like a great solution, and an upgrade that will pay for itself, but since airsoft "hibernation" season is comming, ill wait.
