The hunting scope/optic has no damage (cracked glass etc) state overlay like other optics have. This makes it perform equally well regardless of its condition, making it kind of overpowered compared to an Acog or PU scope that become more or less useless already at Damaged.
I believe some other optics also lack overlays for damage states, I will add these to this ticket once I have tested them all.
Get a hunting scope, damage it somehow - look through it. No visual cue that it is not in pristine condition.
Other optics that also lack damage states:
Range Finder
Binoculars
Kazuar/1PN1 nightvision scope (oddly enough the Starlight/NV-PVS4 nightvision scope does have a damage state overlay!)
Yeah, shouldn't be a major undertaking to provide these optics with a couple of overlays to even the field.
