Processor trigger unit for VFC G28/HK417

Perun for G28/HK417 by VFC replaces stock trigger block with our own housing that includes integrated Clicker and Perun electronic board.

It introduces magnetic trigger detection and optical selector and sector gear detection for most reliable operation and impressive trigger response. Built-in adjustable Clicker allows to set the trigger exactly according to your preferences in terms of pretravel, overtravel and trigger break force.

• Adjustable integrated Clicker – Simulating trigger of a real firearm, built-in Clicker requires certain force to be placed on the trigger to “break” it, before a shot can be fire. This force can be set to user’s preferences, also including reducing it to zero. Pretravel (the leeway before the break is met) and overtravel (distance that trigger can travel when it is pulled all the way back) can also be adjusted.
• Adjustable trigger sensitivity – The trigger can be set to 8 sensitivity levels for both first and second trigger stage, ranging from short pull needed to fire a shot, to a long one. No modification to the trigger or the gearbox is needed, and the trigger sensitivity change is possible even in the field.
• 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.
• 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).
• Selectable firing modes - User can choose firing modes available after short or long pull of the trigger:
  • SEMI ONLY
  • BINARY
  • SEMI-AUTO
  • SEMI-BURST
  • 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.
• DMR mode - Required on some fields for DMR replicas. It allows only single shots and within certain time intervals. When enabled, follow-up shots cannot be fired sooner than after 0.25 s, 0.5 s, 1 s, 2 s or 3 s, depending on chosen setting. It can also be used voluntarily for more realism – to force the shooter to not fire too fast, reflecting the effects of recoil in a real 7.62 mm rifle.
• DSG mode - a sector gear detection mode specially prepared to work with dual sector gears.
• 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.

Programming

Programming of all the settings is done solely by selector and trigger. 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 for G28/HK417 by VFC works without problems with any battery from 7 V to 17 V. It can also be used with most extreme setups.

Safety

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 when a short circuit or blocked motor is detected.
