ROSSI V1 ETU – Electronic Trigger Unit for V2 Gearboxes

The ROSSI V1 ETU is a compact, reliable electronic trigger unit designed for Version 2 AEG gearboxes. Known for powering the ROSSI Neptune Series, including the L119A2, this ETU brings faster trigger response, improved electrical efficiency and consistent cycling to standard V2 platforms. It’s a simple, drop‑in upgrade for players who want modern electronic control without the complexity of full MOSFET programming.

Key Features
