What is the number of lenses in the ATACR and in the Comp?
How are they grouped?
Which is the lens that is missing in the ATACR?
Can you explain the reason why that missing lens would have an effect in the mirage?
You should already know this stuff. Very easy to do research. Like I said, competing without knowing the basics is never not funny😂😂.
Here is a start.
F1 scopes dont have the reticle lens housing(black housing near ocular). AO scopes don’t have the side focus lens group(also black in front of erector assembly)
