Sight Orientation.

[SDSmlf]

Is this your gun? I am unaware of any assembly or rule book. If something for over the mantle, maybe one thing. If something to attempt to shoot accurately, maybe a different answer. My ‘shooters’ look like the one OP photograph. If it were to bother a future owner, believe the technology exists to reverse. I see this as a non issue and totally up to the current owner.

What I found the trick for the rear sight and old eyes. After the front it in place. Set your rifle on a flat surface (we used a fence post) and tape the rear sight where you think it should be, then move it down the barrel until the picture is crystal clear. Mine is a foot down the barrel. The was 15 years ago, and I can still see it in focus.

I only have one gun that I installed the sight in reverse on.
It's a Kentucky pistol, I just like the look of the front sight and had to do it in reverse, or I would have had a short bayonet on the front.View attachment 115464

My sights are in the opposite possition and are as they came from the factory. I don't know which is right or wrong but I do know that some sights are like mine and even under cut to ward off light reflecting back to the shooter, I suppose? Target pistols are a good example of what I am trying to describe.
