Williams™ Aperture Regular 1/2" Diameter with .125 Hole 

Williams™ Aperture Regular 1/2" 1432 are designed to be used on Williams™ Redfield and Lyman receiver sights. The Williams™ Aperture Regular 1/2" 1432 creates a sharp contrast that gives quick definition to the aperture. It is important to note the following when choosing the correct Aperture for your sight:


  • The fractional dimension is the outside diameter of the metal aperture.
  • The decimal dimension is the size of the hole drilled in the aperture used to aim.
  1. This aperture is one size ... review by Joe on 6/27/2017

    This aperture is one size up from the .093 sized aperture that comes standard most Williams peep sight units. It gives a slight but noticeable increase in the field of view. Centering the front sight in the middle of this larger aperture is still relatively easy. The 1/2 inch ring size gives my old eyes better contrast than the standard 3/8 inch ring. Quality and precision of manufacture was the same as that of the 3/8 x .093 it replaced.

  2. Just what I needed review by Pat on 6/27/2017

    Mounted Williams target rear sight but standard small aperture was too small for offhand shooting. Large aperture gives great sight picture.
