Any reason to run a rear sight so far forward?

age. my old eyes like a rear sight a bit further forward.

but try the rear sight in both positions; i bet you get quicker target acquisition with a forward read sight (esp for cqb stuff likke in the picture). think scout rifle.
I’d agree for a notch rear sight but with a circular aperture rear sight it’s not really supposed to be in sharp focus anyway…your brain just naturally centers the front sight in the aperture. Having an aperture sight that far forward will slow you down trying to line up the front post in a small circular aperture. Not sure what type the pictured sight is, though.
 
In many stressful situations, the sights are seldom used as anything more than direction indicators. They may be aligned for accuracy, but the shooter usually wants as much of the image and surrounding area as visible as possible. This is especially true for up close and personal shooting.

The shooter in such cases will practice using the sights as "indicators" to save time getting on target. At closer ranges, pinpoint accuracy isn't usually an issue.

For shooting distance or when pinpoint accuracy is required, and there is time to acquire the sights, then an individual might like them to be further back.

Open, tangent, notch sights are a different ball game, as your eye doesn't automatically center the front sight in a "ghost" ring.

Some folks can and do learn how to focus and acquire sight images very quickly. In my case, that wasn't one of my areas of expertise, so when stressful situations were happening, up close, taking the time to properly utilize the sights wasn't an option.

I've spoken with individuals who only used the front sight hood while looking over the rear sight when shooting under stress.
 
Yes,

-Faster site acquisition (note both eyes are open)
-rear aperture isn't blocking any minute of FOV (again, both eyes open taking on as much info as possible)

It can be argued that at room distances sights aren't required for "IPSC" sized targets. But never say never.....especially if there's non-combatants in the mix.
 
Looks cool & makes a good photo op 👍😎

How old is that photo? they don’t make that barrel & FSB anymore 🙄, LOL. I want to get some of buddies ear pro though 👍😎
 
The front of C79A1/2 sight mount is angled so the BUIS fits in front.

You mount it behind the C79 sight and you cannot get the eye relief.

Most don't even issue you the BUIS, let alone zero with it. Unless you are the Navy. Only branch that uses the BUIS as their primary sight. Which is setup like a Old M16A1.

Judging by the blue colt carrier I'm gonna guess he took off his C79 to shoot simunition in some sort of indoor training where a fixed 3.4x probably isn't ideal.
From what I've seen they mount the BUIS in front of the C79 to get better eye relief with the C79, the BUIS is just a backup after all.
Alot of the rubber sights ontop of C79 are ripped off. I remember doing CQB with C7A1 trying to use the sights ontop.

shouldnt be that old of a pic, the gun holding the gun is using the CADPAT MT uni....couple of years maybe
 
Because that backup sight is designed to sit infront of the C-79 Optic. Youll notice the curve of the backside fits the front of a Elcan closely.

I had one on my rifle when I was over in Latvia, its not as bad functionally wise at it looks.
