Swivel Machine(Airrow Stelth) were years ahead of their time

Arrow guns come into fashion every 5-10 years, but never really seem to be too popular. Never owned an Airrow Stelth, but I did own an FX Verminator Extreme full kit with pellet barrel, arrow barrel, and 2 scopes, in .25. I thought the arrow barrel would be the ultimate urban stealth weapon, until I found out how LOUD it was shooting arrows, and there is no way to moderate it. I don't see a big market here. A crossbow would be a better choice.
