Hi to all.

Got a night force scope with a zero stop elevation control and a side to side adjustment knob for windage.

On both of these the grub screws now have a sudden alarming habit of coming loose and the sights go out of whack completely.

Once the screws are loose and you bouncing in the bakkie, you talking about the scope becoming 3m wide at 100m!!!

This is a .260Rem that normally shoots 1" group at 500m. Now you cant even get on paper at 25m. Have to boresight like a new mount.

Loctite??? Blue?? Red? Any other pointers?

As always, thanks in advance for the help.

Cheers.
