597 ISSF Crossover Rear Sight Prism by Gehmann
Key Features:
- For shooters with one defective eye wishing to shoot with the other
- Completely waterproof with an external lens at either end for water and dust protection
- Centre to centre sight line displacement of 65mm gives no physical change to the sight picture but does require use of a larger than usual aperture
- Attachment is direct to a standard 1″ sight disc – or if using one of our shorter irises, via 597A – or a longer iris, via 597B
- A 1″ knurled outer ring is used nearest the eye for attaching an eyeshield or eyecup
