Tracers Rounds (From SimHQ)

[Royraiden]

The aperture on a lens mimics the human pupil.The bigger it gets, the more light comes in.Also from the videos I saw,the tracers look larger when you look at them closer to a perpendicular angle,so being on a parallel angle with the tracers should result in them looking even shorter.Anyways we really dont know if those are the final tracers.We should wait and see.
