One blaster conversion I've seen quite a lot, both sci-fi and steampunk, is the Nerf Maverick Rev-6. [link=http://www.google.co.uk/search?tbm=isch&q=steampunk+nerf&biw=1280&bih=808]This quick google search[/link] shows how popular it is, as well as showing up a few others too. I was on [link=http://www.iwantoneofthose.com/]iwoot[/link] just now and found [link=http://www.iwantoneofthose.com/gifts/toys/water-wars.list]this page of stuff[/link]. Personally I can see thirteen or so that would make excellent blasters or steampunk weapons, like the Barricade RV-10. I'm curious to see if anyone has already used one of these guns or anything similar. Pictures, hints, tips, etc, would be awesome too.
