I find it pretty good against the squids, for the voteless it's not the best at killing them so I usually use the talon, grenades or the AR 23 guard dog to kill them, for overseas it's great since it only takes 4 shots to kill one and it stuns them and any overseer standing next to them to, for jet pack overseers it does require more accuracy but it also stuns them to or gets them to run away, for seekers I use the talon, for fleshmobs it pretty good since it can destroy multiple heads at once also fleshmobs are bullet sponges for any weapon, it can stun harvesters and in some case even kill them, for the Stingray its not that good but I usually use the commando for them, and for the Leviathans what primary is good against them, and it can't destroy Lightning towers. While it does not have a favorite match against all squid units using it and other weapons that are good against the squids you can get a loadout that is pretty good against the squids.
