  1. Clear Sight Picture. review by 30-30 Plinker on 6/27/2017

    The Williams Sight that I purchased for my Win 94 SE was nice other than it had the .093. The .093 had to much \"spare area\" for me to get a consistant sight picture. The .050 seems to had eliminated the extrea area and now perfect sight picture everytime.

  2. great replacement aperture review by Chad on 6/27/2017

    I had lost the aperture on my old wood pump pellet guns Williams sight when I was a kid...this aperture replaced it perfectly... I honestly think it was the same one.

  3. Well made, great value! review by Steve on 6/27/2017

    This Williams aperture was exactly what I needed! The smaller aperture opening gives me a sharper front sight picture than the standard aperture opening. The aperture is well made, and a great value!
