579 combined with iris and 1.5 magnifying lens, -5 to +5 dpt.

Iris adjustable over a wide range, from 0.5 – 3.0mm 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 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 Iris blades are firmly connected to the base body, therefore a shift in the point of impact is completely impossible! Light reflection is kept to a minimum by applying a special matt finish to all external and internal surfaces A revolutionary iris and magnifier assembly which permits correction of diagnosed axial and spherical problems in the shooter's eye For more information on the corrective part of this unit please refer to our description of 579 Gehmann patented, so not available from any other manufacturers Laser engraved indications Optics 0.0x WITHOUT magnification, dioptre adjustment from -5.0 to +5.0 dpt.
