Placeholder My Tiburon: https://goo.gl/mgTP8Q My Sibaris: https://goo.gl/MKiokG Not entirely sure why DE designed them this way, but while the two share a lot in common, the Tiburon Prime outpaces the Sybaris Prime in accuracy by a wide margin. This allows it to accommodate Heavy Caliber with no significant penalty which gives it a serious edge over most other battle rifles (its even way more accurate than many sniper rifles). Sure, I suppose you could put Heavy Caliber on the Sybaris too, but it turns its accuracy to shit... not exactly something you want with a burst fire rifle. However, even WITH Heavy Caliber, the Sybaris still falls behind in damage compared to the Tiburon.
