Gehmann 510 Rear Iris

The Gehmann 510 Rear Iris will allow you to change the aperture size in the rear sight, to allow for vairing light conditions and to give you a better sight picture.

• Very short and adjustable over the wide range of 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, 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
• Laser engraved indications
• Thread: M9.5 x 1
