[QUOTE="Varmartin, post: 367347, member: 8554"] Loosing your elevation Zero( being a whole turn out ) is something that does not happen very often if one is careful, but could have serious consequences if unnoticed ... I thought long and hard about marking the turret some how to help remember which line the turret needs to be set on for zero. I could have returned both my NXS scopes to Nightforce and have them fit `zero stop`elevation turrets , but that would have cost a couple hundred ££.... so i thought about a different solution. This is what I did. First I removed the turret by slackening the single hex grub screw about five turns out. Using a Dremel, I drilled a small hole in the lower edge of the turret on the zero line. I then refitted the turret and tightened the grub screw. Using the hole as a guide I spun the drill bit by hand to mark the inner column. I then rotated the turret two full turns ( 20 MOA ) and marked again in the same fashion. Now when the turret is removed I was left with two small counter sunk part drilled holes which I filled with paint. The lower zero hole in green and the upper in red. I used a 2mm drill bit in the Dremel for the turret hole , then spun a 1.5 bit for the marker hole in the column...then opened it up with the 2mm bit for the paint. The turrets just pulled off, but i did notice there was a vacuum indicating a very good seal .. Please note ..I have no intentions of swapping scopes around between different rifles and have 20 MOA rails fitted to both rifles these scopes are on , so cannot see any issues in the immediate future with carrying out this mod... See images attached for a shooters eye view of how it looks... This image is my turret set at a 100 yard zero... [IMG]http://i587.photobucket.com/albums/ss311/varmartinhubbard/IMG_0232.jpg[/IMG] This image is with the turret set at 20 MOA. ( two full turns up ) [IMG]http://i587.photobucket.com/albums/ss311/varmartinhubbard/IMG_0233.jpg[/IMG] This image is with the turret removed but sat on the adjuster to show both marks.. [IMG]http://i587.photobucket.com/albums/ss311/varmartinhubbard/IMG_0234.jpg[/IMG] I could have made the red hole location pretty much any where on the scope column, but set it at 20 MOA. This modification will only ever serve to indicate my 100 yard zero and nothing else. If I am more than one turn away from that reference point it shows in the `window` to serve as a reminder ... Any comments or other ideas are always welcomed ..so fire away ..so to speak . :D [/QUOTE]
