This is the closest examples I could find from real guncams "laser-like"
tracers...I know these are not Spit or Hurri ammos, but still....
I would say that what we have seen so far from COD:

They are a bit to large and long ... and to even...
When the are further away, they could look more like a dot and seem to "float"...
They could have a bit of faint smoketrail...
