Some people reading this might say "that's a cool idea - but I don't want my kid inhaling Nerf darts". Sooooo, I being a parent of young kids, had this same paranoid thought so I made an ANDIP "anti nerf dart inhaler piece" for this gun. Simply take an extra 1/2 coupler, drill a small hole and glue in a diagonal piece to block darts. Insert a dart into the barrel from the back of the gun then slip on the ANDIP - then blow real hard. The downside is that the ANDIP slows the loading process down but it does prevent darts going the wrong way.
