597 I.S.S.F. crossover rearsight prism
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
