The Axis Sight Leveler universally assists in tuning sight bars and scopes for precision adjustment of the 1st, 2nd, and 3rd sight axis. The 6,000 series machined aluminum sight leveler is custom fit to integrate with any Versa-Cradle clamp. For those without a Versa-cradle, the flat surface of the sight leveler accommodates any C-Clamp. The three set screws allow for easy adjustment to bring your sight to level status before making axis adjustments.
