The Perun V2 Lightning ETU (Rear Wired) is a high-performance electronic trigger unit engineered to replace conventional switch trolleys and cut-off levers inside Version 2 gearboxes. Routed to the rear, this variant is optimized for carbines and rifles that store batteries inside buffer tubes, crane stocks, or fixed stock compartments (such as M4, AR15, and SR25 models).

At its technical core, the Lightning ETU utilizes an advanced array of contactless optical and magnetic sensors, completely removing moving switch components that are prone to mechanical failure, contact burnout, or arcing. The unit natively supports high-performance brushed motors as well as state-of-the-art brushless (BLDC) motors, ensuring consistent cycle completion regardless of load. Furthermore, it is fully compatible with Perun tactile accessories, including the Clicker V2, Clicker V2 PRO, and Speeder V2 modules.

Supporting input voltages from 7V up to 17V, the Lightning unit accommodates 2S through 4S Li-Po and Li-Ion power sources. Settings are altered in seconds directly through the weapon's fire selector and trigger without external links or cables, guided by acoustic beeps and an onboard multi-color LED. Onboard diagnostics proactively guard against short circuits, mechanical jams, and thermal spikes while an audible low-voltage monitor alerts the user at 3.7V per cell.

    • Contactless Optical & Magnetic Tracking: Complete elimination of mechanical cut-off wear and contact degradation.

    • Brushless (BLDC) Motor Optimization: High current handling designed for modern brushless and standard motors.

    • Precocking & Active Braking: Lightning-fast shot reaction with zero motor overspin or piston strain.

    • Broad Drop-in Fitment: Direct fit across VFC, Tokyo Marui, Specna Arms, G&G, LCT, Retro Arms, and more.

    • Tactile Module Ready: Directly accepts Perun Clicker V2 / Clicker V2 PRO / Speeder V2 units.

    • Comprehensive Circuit Protection: Guards against stalls, dead shorts, thermal overload, and Li-Po deep discharge.

  • Important Operational Notes:

    • Always disconnect the battery when the replica is stored; the unit draws a tiny standby current that can slowly drain cells.

    • Never connect power supplies exceeding 17V to avoid permanent semiconductor damage.

    • After running precocking, discharge the mainspring by setting the selector to SEMI and holding the trigger down for approximately 3 seconds.

    • Take care during assembly to seat the wiring harness cleanly in the shell channels to avoid pinch damage from the motor pinion.
