This field uses energy limits not FPS, it's 1.5J max for normal guns and 2.0J max with 50' minimum engagement distance for snipers. Rule of thumb to be below the limit is 4OOFPS with 0.20g BBs for normal guns (Rifles and Pistols but they rarely check pistols), and 460FPS with 0.20g BBs for snipers.
I dont know the airsoft limit. Paintball is 285
Wow did not know there was a limit. Sorry can't help you.
