After seeing it mentioned on one of the GB forums, I ordered up a sourdough front sight from Brownell's.
Installed it on my Win 71 and took it to the range last week. Wow, for punching paper I LOVE it. I was able to shoot much more consistently and got tighter groups than with the old silver bead. I just wish the blade was a little thinner. Might order another and thin it down myself.
Don't know how it will perform for game shooting but it sure presents a much clearer sight picture for me. I'll be putting one on my Win 94, possibly some other guns as well.
