At least he realized the fact his Holosight was on backward as evidenced by the back up iron sight in the raised position...
I would not think the primary sight would not be stored on the carbine, however, zero would be compromised.
I don't believe he's realized anything at that point.
I have the same Eotech sight, so I just had to check to see what you could see through it backwards. Unless you are totally high on adrenaline or something else, you are going to notice very diminished light transmission.
No qualified marksman would ever slap optics on their weapon and not zero them.
Makes me suspect these boys have never played with their toys before.
“I would not think the primary sight would not be stored on the carbine, however, zero would be compromised.”
Probably some but not enough to notice. The Eotech is a short range “tactical” sight. It has no magnification so the range is limited to, maybe, 200 yards. What the Eotech does is give you very fast target acquisition and a laser like red dot on the target seen through the scope. Of course there is no actual red dot for the target to see and nothing shows on the front of the Eotech scope. While I’m sure the zero is affected some I don’t notice a difference when the Eotech is put back on the rail in the same position. Using the scope for targets 100 yards or less feels like cheating.
