hi!
sooo ... the government isn?t interested in airsoft in any way, so the clubs have to make their own regulations, ...
regulation for muzzle velocity in this club here is 360 fps with 0.2g BBs ....
you must not carry the gun visible in public, ... it might be good to put it into a guncaseh or something else, .... how you carry the gun inside this guncase (loaded, unloaded, with or without accu, .... ) doesn?t care anybody, ....
and sites .... well .... thats another story, .... its a little bit complicated, ... if you are more than 4 people, law considers you a "milit?risch bedenkliche gruppe" (i.e.: a group, that can be dangerous for the military, .....) so you have to rent a site AND you have to have a club witch organises the game officially, to make the game legal, ....
sites dont have special regulations ..... it depends on where the sites are .... if the site is in a wood, where are a lot of poeple, then it might be better to place warning signs alont the edges of the rented site, so that nobody gets hurt .... but the law has no special regulations, ....
