Skorpion and Chicom fire at 1200 i think, and the vector and mp7 fire at around 900 lol. And skorpion has abysmal range. The M8A1 fires faster than the SWAT as well. Stock solves mobility and you shouldn't be up close with an AR anyways. AN-94 is a great assault rifle along with the MTAR, Type-25, and Scar. The M27 is decent, and the FAL and SMR are really good. The M8A1 is amazing and the Swat has a very long 1 burst kill.
