Most Realistic GUI/Optics mods?

[BillCar]

In the month since getting SH3 + GWX 3.0, I have gone from 89% realism to 95%. I'm preparing myself now for the jump into obsessive realism.

With that in mind, I've started looking for realistic optics interfaces. So far, it looks like OLC is the best one, but I am not TOO knowledgeable as to what I should expect from my optics, targeting materials, and so on. Is it reasonably realistic?

So far as I can understand, there were no stadimeters, and the UZO didn't have a rangefinder. Both scopes should run at 1.5x and 6x, as opposed to the 10x and 4x (or whatever) in the stock scope config.

OLC also has that great attack wheel, and the range/AOB/speed finder. I am still new to researching this stuff. Are these tools historically accurate? I sure hope so, because I do love them.

Any recommendations / suggestions / corrections are appreciated! I want the most realism that can be afforded from my computer chair.
