1. What the setting is

The “eye relief” or “pupillary distance” option in the gunsmith menu is described Delta Force Tekniq Alloy as a simple scope-position adjustment. It changes whether the optic sits closer to you or farther away from your view.

2. How it works

The source compares it directly to grip placement:

• Adjusting a grip moves it forward or backward.
• Eye relief does the same kind of thing for the scope.

So, instead of changing zoom, this setting changes the optic’s position.

3. Why it feels confusing

The confusion is said to come from presentation, not from the mechanic itself. The speaker wonders why the game does not animate eye relief the same way it animates grip movement.

Because it is not shown as clearly, players may not immediately realize that this is just a forward/backward positioning adjustment.

4. Does it matter in gameplay?

Yes, at least slightly. According to the source best site to buy Delta Force Items, moving the sight farther away toward the plus eye relief direction gives you slightly less visual recoil.

So the effect is not purely cosmetic, but it is described as small.

5. Main takeaway

If you see this setting in the gunsmith, think of it as:

• scope distance adjustment,
• closer or farther positioning,
• and a slight visual recoil benefit if moved farther away.

Overall, the setting is simple: it changes how far the optic sits from your view, and pushing it toward the plus eye relief side may slightly reduce visual recoil.
