PLB-0001-140 LaserLyte’s Laser Scope Leveler provides the ultimate in scope mounting precision for the highest level of sight-in consistency. Designed to be used with any LaserLyte Laser Bore Sighter, this unique accessory assures that the reticle is “square” before you tighten the scope in its mounts. Simply attach the Laser Scope Leveler to a Laser Bore Sighter, insert in bore and you can match the horizontal crosshair to the projected horizontal Laser beam. Tighten scope mounts and then you’re ready for sight-in! The scope’s windage and elevation adjustments require the reticle crosshairs to be level–or square–for exact sight-in accuracy.
