As i do marshall at various sites, i do take a chonie on the field with me , & if i hear something out of the ordinary after they were tested prior to a game they get BANNED...Not a nice thing to do on the field as some of the punters do object to " gun owners " taking theirs onto the game zone, as i make ALL gun owners turn them down to 280fps...My prerogative...or if you hate the opposition take a allen key and do a crafty turn or three :O who said that?????
