One of my nephews stopped by the other day, he's really into guns, has a pretty sizable collection, for a young buck in his 20s. He was showing me some sort of device he had for when you scope a rifle it was supposed to make your reticle level. It had all kinds of stuff on it, magnets, level bubbles etc.
He said what do you think of that uncle?. I said that's pretty impressive!. I said to think all these years I said all I have been using is a piece of string taped onto the wall with an nut tied to the end of it hanging down to line up my crosshairs, I said gravity don't lie :biggrin: .
He pondered that for a moment and said damn that actually sounds like a good idea. :wink:
