My first sight had 6" overall length, I had my pins at 10, 20, 30, 40 meters...my last pin was at it' s lowest position (45 meters), and the sight bracket was at it' s lowest position...just enough for vane clearance.

I replaced that sight for a sight with an overall length of 8" ....the extension bar was 6" . I thought that if the sight bracket was further away...I can use the last pin for the 50 meters target. You mean I' ll have to bring the sight all the way back to the riser to be able to use all 5 pins?

All this time, I thought the " spot" shooters were using their sights with really really long extension bars ie. toxonics or sur loc sights, so they can aim further....80 or even 100 meters.
