  • Ultra compact mosfet
  • Active braking function helps prevent wear on the main spring and double shots
  • Excellent for high rate of fire/high power tunes
  • LiPo battery protection
Perun AB is one of the most durable systems of this type on the market, while maintaining small dimensions. In addition to the Active Brake (AB) function, which prevents wear of the main spring and double shots, it also has a Li-Po battery protection mode. Both functions can be switched on or off as required using the button on the housing. Because Perun AB is controlled by a microcontroller, it is completely immune to the so-called contact vibrations that may cause damage to systems based on other solutions.

We do not give maximum parameters of replicas in which Perun AB can be used, because it works without any problem even in the most powerful configurations, both in terms of rate of fire and outlet energy.

Permissible Battery Voltage: 7V-17V
Dimensions: 20mm x 13mm x 7mm

Manufacturer: Perun Airsoft

About Perun

Perun was established in 2016 with the aim of designing and manufacturing MOSFET devices and other parts for AEGs. After years of designing and testing, we offer you products that will work reliably even in most extreme situations and enhance the capabilities of your replicas.All of our design work and most of the manufacturing is done in the European Union state of Poland. That allows us to reach our main goal - keep the highest quality possible. We are in constant contact with players, airsoft techs, shops and consult with them to ensure that our products satisfy their needs.

"This is an extremely capable little mosfet. I don't know what they put in the water in Poland, but between Perun and Gate, they're churning out incredible hardware right now (no offense to Jefftron and the CZ guys, I just haven't used your stuff yet).

I'll let you in on a secret: this *might* be the perfect AEP MOSFET. I crammed it inside the slide, next to the inner barrel on my HK USP AEP (EF/Umarex). It's perfect: all the features you need, none that you don't.
Oh, you might need to take the plastic sleeve off the inner barrel to make it fit.

For me, I needed active braking (11.1V was causing double-shots on the pistol), and LiPo voltage warning. This was the only MOSFET I found that had both those features, fit inside the gun, and didn't have extra stuff (aka huge connectors). And for the price it's a STEAL.

Programming is as simple as holding down the button for a few seconds. It comes with a big shrink-wrap sleeve to protect the unit once it's installed.

Oh, and it probably gave me a 5rps increase after installation. If you're using 11.1V batteries, I definitely recommend it; it'll save your trigger contacts, and warn you before you undervolt and destroy your batteries.
