Out of curiosity, why does it interest you? Seems to me it'd be a lot cheaper (and make more sense) to snag a decent flashlight. Like a streamlight 88040, $20 more than the phosphorce (if diy or alt costs similar) and likely to be way more efficient.
Oh lookit you, sellin a las0r. Honestly you probably shouldn't have stickied this thread, I (and I'm sure I'm not alone) tend to ignore most of the stickies if I've read them in the past. Can you wait to sell this so next week you'll have it for my visit? Come on.... :D
My current project: http://i55.tinypic.com/208cnfd.jpg
It's a .338 Lapua Magnum. If there was some way to accurately mount and calibrate a laser for say, 1500yd zero, I'd do it. On pistols and some rifles there's a laser sight that mounts in the bore for the most accurate sighting.
I was recently playing laser tag (ha ha! lasers!) and the place we were at had a laser obstacle course, they seemed to use green with minimal fog. Seemed like each laser was around 10-20mw (eyeing) with some light fog, and they showed up clearly enough. I can find out what they use if you want.
