Rifle Scopes EXD vertical reticle insterment video

[AR15-SBR]

I watched a video a while back and now can't find it. It had a couple guys using this tool in a darkened room shining a flashlight "backwards" through the scope. The image of the reticle shown against a wall that had a plumb line on it and they "plumbed the vertical crosshair to the plumb line.

If anyone knows of this video I would really appreciate a link to it.

Thanks
