Back in the 80's I had a great one. It used spring steel wire and plastic beads for the darts. You could get the blowguns all the way up to 7' long. Mine was only 6', it was very accurate and I took every thing from lizards to the occasional cat.(Don't tell my neighbors!) The thin steel wire could even be sharpened for better penetration. The company that sold them went under and I eventually ran out darts. I wish that I still had one though!
