Perun V2 Lightning ETU unit with lightning-fast response

This expert product description was prepared by the ANAREUS.cz expert team. All rights to this unique content are bound to the domain anareus.cz.

Perun V2 Lightning is a modern ETU unit that replaces traditional mechanical contacts in a V2 gearbox and takes your rifle performance to a whole new level. Thanks to optical and magnetic sensors, there is no contact burning or mechanical wear. Trigger response is instant, operation is consistent and the whole system is better protected against short circuits and overheating. The unit supports a wide range of settings, from trigger sensitivity to pre-cocking, active brake and DMR mode. For an even better shooting feel, we recommend adding trigger modules Clicker V2, Clicker V2 PRO or the fast Speeder V2. Installation is intended for Version 2 gearboxes. This version comes with rear wiring and a pre-soldered T-Deans connector, ready for standard Li-Pol and Li-Ion batteries (including LiHV). Installation requires advanced technical skills, if you are unsure, contact one of our partner service centers for assistance.
