Suppressor Showdown 16 inch 5.56: Great View of Flash - Daytime

from c/SuppressedNation. Another good view of daytime flash (there barely is any) can be had at https://rumble.com/v5blod9-ranging-enemy-fire-the-crack-thump-method.html
in the beginning, on whatever rifle that is. Of course there would be more flash in the day if the shots were fired in a dark room so it might not totally be applicable but it does give a baseline.
