Default More info

I found on my two scopes that both top turrets had one grub screw missing (from identical positions as well, how strange). Even though the turrets function well with only two screws I felt the need to have a full set (sad or what). My local nuts and bolts supplier (Lincs Fasteners) was very helpful and between us we worked out that the screws are M2.5 thread and the allen key required is 1.3mm or .050".

Worth knowing if you lose any.
