The simple, clean design of the Segway Reticle Leveler makes
it the best anti-cant device on the market. The MK-III works with rifles,
shotguns and handguns and it mounts in a snap. Here's how it works: the plastic
squares go on either side of your scope. Each square is double-sided with
narrower lines on the reverse side to accommodate different vision preferences,
so choose the side that works best for you. Next, just adjust and re-position
your scope to align your reticle's crosshairs with the black lines on the
leveler and that's it…you're ready to shoot! No more guessing, no more
frustration, and no more hassle.
