Power
Above Italy's 1 J limit
Italian shops sell versions tuned below 1 J: ask the shop which version they ship.
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.
