Leopold zero point magnetic bore sight - Leupold Zero Point Boresighter

This bore sight tool is a must have, it works for scope - open sight-handgun,rifle,or shotgun- even used it to zero the scope on a air rifle. Simply attach it to the end of the barrel adjust the x hairs on the scope to the ones on the Leopold boresighter remove the tool and take a shot poof it's on paper at 100yds. For my black-powder mu slug gun 22lr 3006 and Springfield XD40 if not dead on they were just a "click" or two off. How simple was that? I mean REALLY! and it comes with mini cards to keep track of grain- drop-in and what ever compensation was needed for which firearm. I put mine under the dust caps on my scopes or under the butt plate for those with open sights. Great tool now I hear it's dis- continued! What?? If it's truly discontinued and you've got a chance to get one somewhere somehow I'd advise you to grab it keep it and pass it down to u next sharp shooter in your family. GET ONE!
