Clicker V2 PRO is an accessory designed for use with Perun drop-in devices for V2 gearboxes like Perun V2 Hybrid or Perun HPA Trigger Board V2. It introduces up to 3 kg (6 lbs) break to the trigger action, which needs to be overcome to fire a shot, similar to how the trigger works in a real firearm. Clicker V2 PRO is meant for realism enthusiasts, and everybody else who wants a tactile feel on the trigger. It can be adjusted in five different ways, to best replicate a real firearm or simply suit your personal preference. In new Clicker V2 PRO, mechanical safety is retained.
