Leader Maintenance on APQS Longarm (extended version)

This is how I maintain my leaders and make sure they are straight. It also extends the time on having to make new casing edges. Side note to video, if you do need to mark a new center, do it with it clipped. It really doesn't matter where they are placed on your leader just as long as the blue marks meet up. I find a "ball park" center for my front leader and then make sure the back mark abutts it.
