One thing is obvious though...It is clear , watching the guncams, that COD's tracers are way to " fat" , too "even" and too long.Some have also pointed out that they were too "fast" ? compared to what they saw in RL... And this has been the conclusions from "experts real military " in this forum since the first WIP were shown.
COD's tracers may be ballistically accurate, but not visually...

SAlute !
