I had a Mountie in the early 60's and loved it, but it had a flaw that bugged me so much, I got rid of it.
The rifle was used for plinking and hunting. From a rest, I could shoot under 3/4" at 50 yards with the receiver sight.
The flaw? The top of the receiver was not perpendicular to the sides. When I mounted a Williams 5D receiver sight the flaw was so obvious it drove me nuts!!! It may not have bothered me to that extent today, or I might have just milled it to make it right.
People are like rifles. Some are tried and true, having great eyes, personality, and fun to be with. Others never seem to hit the mark with you. Still others go off half-cocked. Still, it's nice to know most of them.
