@ATFGunrYou're missing the point of glint. If things were realistic, there would be no glint, because scopes have those honeycomb things, and/or anti-reflective coating, and whatever other reasons. Glint is so you can see faraway snipers; the map, location, angle relative to something that isn't you should not matter.
It might not stick out to you due to how bright it is, but Manifest is a night map. Nevermind all the other weather events on a plethora of maps that introduce something that blocks the sun, most notably Orbital, Hourglass and Spearhead. Getting in a shadowy spot is not too hard.
