Partial data VFC GBB (gas blowback)
VFC T91 FSP GBBR: 1.34 J, 380 FPS, 3,130 g. Full specs from the official source, with FPS for every BB weight.
Power
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.redwolfairsoft.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.
