Choosing which Duplex Insert is right for you:

There are two main indicators for the diameter of the ring :

  • Distance Eye to Iris-Aperture And Length of Lenshood II That’s all you need.
  • If you have Rear-sight Spy, you will need a diameter between 3,8  and 4,2 with a distance eye to Iris aperture of 4 cm to 5 cm
  • Feinwerkbau rear-sight, you need a long Lenshood II, there are 4,3 – 4,8
  • Anschütz 7000er rear-sight also with long lenshood II it´s similar to Feinwerkbau.

Length of sightline or Diameter of front-sight tunnel, doers not matter.
