User blog comment:Helix Armada/ACR=Skorpion, kinda?/@comment-1079585-20100919065647

The Skorpion had very low horizontal recoil while the ACR has none. The Skorpion had so little range that it was doing 20 damage at all but knife range, where it could kill in two hits. The ACR, unless silenced, will usually be doing 30 damage. The Skorpion fired at 850 RPM while the ACR fires at 750 RPM, making the 20 round magazine a huge issue. And the Skorpion had a long reload with a terrible reload cancel.
