handwerk, don't deer see blue very well? Seems I read that once in a story about why they DON'T see blaze orange well.
If so, I wouldn't want a blue dot on the end of my barrel- at least where I hunt, which tends to be be close-up.
I had one day a few years ago that I should have put tape on my muzzle... sloppy slushy snow all day, then it got cold and about froze my rifle solid. I guess enough water got into the rest of the rifle that it might not have even helped, really...
