ORIGINAL: whiff
Quit useing peep when I went full draw on a Buck and all I could see was a drop of water. Use a kisser now.
Was that drop of water in the no-peep lense? If so, they recommend applying some Rain-X to the lense to prevent that very thing from happening.
Anyway, I use a no-peep and I'm quite satisfied with it. I will not go back to a traditional peep site.
