I was in NWAF when I found a damaged T3N RDS Optic and attached it to my M4. I proned in front of an evergreen in third person and ADS to see if the optic's condition would suffice. Instead, I got a black screen when I ADSed. When I zoomed out, it was completely normal. I deduced it may be due to the evergreen I was behind, and moved to a clear, grassy area to ADS again. The black screen returned. When I was standing or crouched I did not have a problem.

I have linked a Steam screen shot of the black screen I have described above in the "Additional Information" section. You can see part of my M4 and the 60rnd coupled mag, but no the sight or anything else besides a bit of the bottom left corner.
