MKV Suppressed states in its description that its supposed to have higher bullet velocity and more stopping power than other SMGs that are using suppressors at range, but this is wrong. I did a simple Damage test compared with the PDW. I went to the PDW's max range, 68m (added 3 in case of waypoint error). Equiped a suppressor + 4x crosshair scope. Tested it 5 times vs. non-infiltrator dummies. It was doing the prescribed minimum damage, 100, at this range. The kill was 10 shots. A couple trials I had bullets hitting the leg or head, so I had to do them over. Compare this with the MKV Suppressed. It has a 91 minimum damage at 45m, and takes 11 shots to kill at that range. It does less damage at range than what the PDW does with a suppressor. It seems that the suppressor's penalty of losing effectiveness at range varies with the weapon. Basic tests with a Cyclone, an 8 shot kill (125 damage) with no suppressor is 31m, while with a a suppressor it drops to 24 ± 2m. It seems like its around 24, meaning that suppressors lowers the cyclones max damage range to 34-36m, down from 46m. Also tested suppressors with the ACX-11. With no attachments, its 6-shot kill range (167 damage) is 50.5m . I then equipped a suppressor, and it dropped down to 35 ± 2m, meaning the minimum damage range dropped from 80m down to 50-55m. I also tested with HVA, and it turns out HVA has 0 effect on damage range. It only affects recoil and muzzle velocity. TL;DR While the description states MKV has the highest stopping power and effectiveness at range for suppressed SMGs, its not true. Comparing it to the PDW, it fires 3.8% faster but takes 1 more bullet to kill at range, meaning its not the fastest TTK of the suppressed SMGs at ranged.
