I’m guessing the “reliability” issues named by users are most often due to improper mounting.
We see certain high quality brands mentioned and I have never had an issue with any of them.
The eye can not see the minuscule amount that scope bases and rings can be out of alignment. Left, right, up and down. Front and rear.
If the tube is in a bind and you hog down to 35 inch pounds because the ring manufacture says to torque it to 35. When the the scope company says 25. Or worse you hog down without a quality torque wrench. And the bases and or rings are not perfectly aligned the tube is in a bind,
And the internals of the scope are also in a bind. Now add recoil to that bind. And then wonder why it doesn’t track any longer.
Of course there are defects. And abuse from dropping or impacts. But I’m guessing the guy at the store or at your house didn’t take the time to align and or lap the rings.
The pointer style alignment is better than nothing. But it still relies on your eye to see thousandth's of an inch.
Better is the sliding ring. If there is any bind whatsoever, you feel it. Left right up or down.
