Partial data CYMA AEG (electric)
CYMA CM128, AEG: 0.34 J, 190 FPS, 760 g, 29 rounds. Full specs from the official source, with FPS for every BB weight.
Power
Within Italy's 1 J limit
Estimated energy: the source does not give the BB weight, so we used 0.20 g, the standard weight manufacturers and shops use to measure velocity. With other BBs the value changes: always check with a chronograph.
For information only, based on the energy the manufacturer declares for this version. Not legal advice: always check current local law and the version the shop sells.
