Gehmann - Rear Iris

(#PH510) Gehmann Rear Iris - Adjustment range 0.5mm - 3.0mm. Thread size suits Parker-Hale or Redfield.

(#510) - Gehmann Rear Iris - Extremely short design and adjustable over a wide range of 0.5 - 3.0mm. The aim-point is precisely maintained through a wider range of adjustment by the introduction of a new system of aperture control, which is operated by varying the pressure of a steel tube against the central aiming ring - this guarantees a perfect circle at any point within the scale. Iris made of hardened spring steel, not brass like other manufacturers, therefore extremely robust, making it also suitable for large calibres.  Thread M9.5x1 for all well-known target rifle brands.
