Clicker V2 PRO is an accessory designed for use with drop-in devices for V2 gearboxes, such as the Perun V2 Hybrid. It introduces a resistance of up to 3 kg (6 pounds) in the trigger mechanism, which must be overcome to fire, resembling the function of a trigger on a real firearm. Clicker V2 PRO is intended for realism enthusiasts and anyone who wants to feel a distinct resistance on the trigger. It can be adjusted in five different ways to best replicate the trigger of a real firearm or simply to suit personal preferences. The new Clicker V2 PRO retains the mechanical safety feature.
