Perun V2 Hybrid replaces mechanical contacts in your airsoft replica or gel blaster and provides lots of useful features. Optical and magnetic sensors allow to eliminate many moving parts that are prone to damage, thus increasing the reliability. Adaptive trigger control allows switching from a very short trigger travel to a long one even in the field, with almost any trigger, including stock ones.

Features Overview:

Adjustable trigger sensitivity: The trigger can be set to 5 sensitivity levels, ranging from very short pull needed to fire a shot, to a very long one. No modification to the trigger or the gearbox is needed and the trigger sensitivity change is possible even in the field.

Independently programmed firing modes: Program the firing modes any way you like, setting safe, semi, burst or auto on both selector positions.

Active brake: active brake stops the motor after each shot preventing spring compression or in case of replicas with high rate of fire, overspin (double shot problem).

Precocking: Fast trigger response can be a matter of victory or defeat, especially in CQB situations. With precocking enabled, piston will remain in rear position after each shot with the spring already compressed, ensuring that next shot will be fired immediately after you pull the trigger. To release the spring after using precocking, pull the trigger and hold it for 2 seconds, after which a second shot will be fired, this time with no precocking and fully braked.

2-stage trigger: Light trigger pull results with a single shot or burst, while a deeper pull will cause a burst or fully automatic fire. Following modes are available: semi burst, semi auto and burst auto.

Binary trigger: Allows for easy double shots in semi-automatic setting. After enabling this mode, if semi-automatic fire is set, shots will be fired not only when the trigger is pulled, but also when it is released.

Rate of fire reduction: Reduce the rate of fire in automatic or burst fire to save ammo or make the replica shoot in a more realistic fashion.

DMR mode: Introduces intervals between semiautomatic shots to comply with DMR rules on some fields.

Low battery voltage alarm: Dedicated for Li-Po and Li-Ion batteries. Should the battery voltage fall to a dangerously low level, user will be notified by short sound signals that are repeated every minute. This may also be freely switched on and off.

DSG: a sector gear detection mode specially prepared to work with dual sector gears.

Diagnostic system: Constantly monitors the replica and the MOSFET itself. In case of any problems, immediately lets you know what it might be, making troubleshooting much easier.

Electronic fuse: Will save your replica and battery in case of a major malfunction. It will automatically disconnect the battery when a short circuit or blocked motor is detected.

Programming of all the settings is done solely by using quick and easily memorable sequences of fire selector switching and trigger pulls supported by sound signals and multicolor LED diode. That allows changing the settings in any moment, in a matter of seconds, even under enemy fire. All settings are set independently for each selector position, so you can program the MOSFET exactly the way you want, for example semi on semi and binary trigger on auto.

Perun V2 Hybrid works without problems with any battery from 7V do 17V. It can also be used with most extreme setups.

"Bought the Perun v2 Hybrid to replace the stock mosfet on my aeg that was kinda trash and annoying. Installation of this perun was a little difficult because my gun didn't come with a cutoff lever in the gearbox since it already came stock with a mosfet. However, you need the screw from the cutoff lever to secure the board in the gearbox, so I had to find a screw that fit and cut it to be short enough while also making a DIY washer out of some plastic packaging I had lying around and a hole punch. I also had to file down the screw that I modified to fit so that the sector gear could spin freely (the screw rests under the sector gear and needs to be short enough not to hinder gear rotation). If your gun comes with a cutoff lever it'll be much easier lol.
Once I got it installed it boosted my performance incredibly!! I paired it with an adjustable trigger and 40k motor and I can spam the trigger super fast and it's incredible. This mosfet comes with a bunch of advanced features you can adjust to improve the performance of your aeg. It doesn't have Bluetooth which is fine for me since I'm fine with tuning the settings manually through the trigger, but if you want Bluetooth connectivity to you phone, this one doesn't have that.
Only complaint is the wires are very very soft and have basically no stiffness which is kinda weird and the insulation around the wires gets cut very easily, exposing the wires. One of the motor connectors also broke when I was trying to connect it to the motor. Probably was just me being dumb and manhandling it, works fine after I soldered it back in place.

I give it a 9/10 only since the price was increased from $74 to $99. One of the main pros of this mosfet over other options like the gate aster or leviathan was it's low price. But now that it's up to $99, it's more expensive than the gate aster II which has Bluetooth AND already comes with an adjustable trigger. So honestly I'd just get the aster or even spend a little more for a leviathan now that the perun is this much. But if the price ever goes back down to $74, it's the best you can get.

"This Mosfet is really good although I do recommend you upgrade your motor if you haven’t already, it will warm up pretty quick due to the high rate of fire

"Tried a Mosfet from another cheaper brand and I brought it under normal use. This thing is a beast, easy to install and easy to program. Does everything I could want it to do and it allowed me to setup my dream gun. I won't waste my money on below $50 priced items again.
