I meant it does not come with a mount... nor anything saying it's an add on accessory.

I'm not thinking it's gun related at all... I mean, Laser's have that covered. I have a Green Crimson Trace laser on one of the carry handguns.

Doesn't make any sense as a 'pointer' either, at least that I can see.

And then there's the color change... black or yellow crosshairs... that just confuses me even more. Maybe it's simply a 'by-product' caused by the bulb configuration when you narrow the beam width? But then why the color change? I just don't know... and it's bugging the hell out of me. - JamesJM
