Feature description

Freely programmable firing modes – Set any firing mode you like on any of the selector positions independently. Available modes are: safe, semi, binary, 2 to 5 round burst and auto.

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 and hold the trigger. A second shot will be fired after 3 seconds, with no precocking and fully braked.

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.

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.

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 if a short circuit or blocked motor is detected.


Programming of all the settings is done solely by using trigger and selector, in an easily memorable and quick sequences. Programming is 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.

Perun for Krytac Kriss Vector works without problems with any battery from 7V do 17V. It can also be used with most extreme setups, without any limitations as to the spring rating.

    Was dubious whether I needed this or not but it makes a big difference. The instructions are clear as it needed programming (manual warned of this but real easy to do). Like this a lot

  2. Verified Buyer (verified owner)

    The installation is pretty straight forward BUT the selector sticker which was not quite easy for average player. Calibration was not too difficult but ONLY SELECTOR is optic sensor but trigger is still a click button. Overall pretty good replacement as my original one was broken. (Forgot to take photo will upload laer)
