nerf is a game(even if played with cursing, bloodthirsty friends, screaming wired warcrys and shooting each other in the head....*teary smile*) just get your parents to understand that
It helps if you play with people your parents can trust
by improving the air flow (plugging up all the holes) you SHOULD get a tiny bit more range. it may not be noticeable, but with some guns it is quite good (splitfire, in particular)
also, if it is a pump gun, plug up the air release hole in the end of the pumper. just be sure not to pump too much, as my good friend head-shot-guy (named such because he gets shot in the face in every one of our wars ) so (un)happily discovered. hairline cracks in the airtank are VERY annoying...as you would imagine
I'm not out to impress anyone at the moment I'm just after a good loser, because it seems to me that the current nerf selection for losing is really lame
