Above Italy's 1 J limit

Italian shops sell versions tuned below 1 J: ask the shop which version they ship.

Energy computed from the velocity with 0.20 g BBs, the standard weight manufacturers and shops use to measure FPS.

The main source does not give the velocity: FPS taken from the page of the same model on www.airsoftzone.com.

For information only, based on the source's data for this version. Not legal advice: always check current local law and the version the shop sells.
