Infinitely adjustable from 0.5mm-3.0mm. Much shorter and adjustable over a wider range of 0.5 - 3.0mm For all well-known target rifles (M9,5x1 thread): Feinwerkbau, Steyr, Walther, Hämmerli, Grünig + Elmiger, Diana, Anschütz etc. The fixed-seat iris works with individually pin-located tempered spring steel leaves The aim-point is precisely maintained through the 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 Light reflection is kept to a minimum by external and internal matt finishes Gehmann patented, so not available from any other manufacturers Laser engraved indications Thread M9.5x1
