    Leupold CDS set/grub screw size

    Hey, Anyone know what the size specs are for the set screws used on a VX3i CDS turret? There’s three of them which hold the turret on.

    Cheers

    Grub screw spec is 4-40, it is 1/4 (0.250) inch long.

    You need a 3/64 hex allen key, in a pinch a 1.0mm metric allen key will work as well.
