Perun AB++ Airsoft MOSFET w/ Burst and Active Braking

"This mosfet is fabulous. Definitely in all in one package without having to replace the entire trigger. I installed this in my Army L85A1, that relies on a circuit break/reversal for precocking. I actually had a Gate nanoasr and removed the factory break wire before but in semi that would leave my piston stopped like halfway thru the cycle (half working precocking). But with this I activated level 1 active brake and oh man what an improvement. I can shoot semi much faster than before without the trigger locking up and it precocks like it did from factory in addition to a notable increase in response. Precocking feature in the mosfet wasnt needed. I tried using burst but it was being probably due to the mosfet timer being calibrated for a standard 15 tooth piston. Im sure this would do wonders on a V2. For now I am very satisfied to have this over Gate's AB mosfet due to the diversity and strength of functions. To install in a Army/G&G L85 you need to pop out the trigger assembly and desolder the 2 positives there and the 1 positive from the factory active braking from the top cover. Then measure out the wire and have the signal wire on the bottom contact and have the positive go from mosfet -_ top trigger -_ motor. The negative can go straight from mosfet to motor. Highly recommended for any standard 15 tooth piston gearbox or 19 tooth even but with less function

"This is a good little mosfet. I adapted this for a Snow Wolf AUG A3 after watching a forum on internet and it actually works very well, of course, since I changed the whole wiring of the gearbox it requires a lot of soldering but is not that complicated, just requires time, and let me tell you, paired with an ASG 18K motor and M150 spring this thing sounds really great and the funtions works great as well!

"Great mosfet and great value compared to others. improve my trigger response Easy to program. Features are good enough for what I needed. There is some soldering that is needed but is not that bad. just needed to solder to both trigger contacts and terminate motor connector. The positive lead to motor is a little short for my application.

"Fantastic MOSFET!!
I got this for my CYMA ak, and after a long installation (dont use a soldering iron that is less than 10 dollars) I got it installed quite nicely. The features are very good, especially precocking which can bring a normally slow winding semi auto to being almost instant, and the burst function is very cool. I can recommend this to anyone who is looking to upgrade their basic rifles to something more capable.

"Awesome little unit for the price. When I say little, I mean little. I had a nanoASR just to protect my micro switch trigger installed and switched it out for this. The nano dwarfs the perun in size, the perun is tiny! pre-wired except the motor spades, wire is super nice quality. Setting it up is easy, the many modes are nice. Comes with a playing card with instructions how to set and toggle modes which is neat. Also comes with mode stickers that can be put on your gun so you always have a reference on the field. I have mine on my buffer tube and my stock hides it. Check out ASTKilo23's review of it. https://youtu.be/10Rjxi8aMn8

Great mosfet!!! Get one!
