Prime Mech Airsoft's custom CZ Scorpion EVO, dubbed the perfect CQB build, is based on the ASG CZ Scorpion EVO 3 A1. Upgraded with the Leviathan EVO3 processor-controlled MOSFET, this AEG offers a plethora of advanced features. Replacing the original electronics, the Leviathan seamlessly integrates, retaining original functions while adding new shooting modes, adjustable burst lengths, rate of fire, pre-cocking, active braking, bolt-catch simulation, empty magazine warnings, shot delays, electronic fuse, low battery indicator, and data logging for fine-tuning. Paired with a stock motor, 13:1 13-tooth SSG, and a 1.1J output at 0.30g BBs, this customized Scorpion EVO is a formidable force in close-quarters combat.
