Actually this issue accured with 1.42 update.

So the zoomed optic mode reticles (the deltas) are to thick compared to RCO zoomed optic reticle (dot).

It is hard to aim with the to thick reticle. I know it sound like a minor thing, but it was ok with before, now it is like 4mm thick.
That is not so clear anymore how to aim properly imo. {F26209} {F26210} {F26211}
