530 Iris with 1.5x Diopter by Gehmann

Key Features:

• Extremely short design and infinitely 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
• Laser engraved indications
• Optics 1.5x dioptre with -4.5 to +4.5 dpt correction
• Optics can be unscrewed and replaced by the 577-thread adapter to obtain a “classic” iris setup without dioptre adjustment
• Thread M9.5×1 for all well-known target rifle brands
• Instruction manual included
