Apertures for TechSights 200

Apertures for TechSights 200
  These new one-piece apertures for the TechSights 200 peep sight allow you to change peep-hole sizes to suit the available light where you're shooting. It works much like a camera aperture in that, the smaller the hole, the better the focus. Of course in low light, you need a bigger hole to be able to see. And in bright light, you can use the smallest aperture and see the clearest sight picture. We have replacement apertures in sizes .062, .086, and .125 peep hole sizes. Choose the best size peep-hole (aperture) for your available light. The apertures are designed only for the TechSight 200 model (and won't fit the TS100).
  Note: 062 is what the standard TechSight 200 comes with so... Don't order .062 unless you need an identical replacement.
