If so, how?

I just went through there with Fawkes and Dogmeat and it still took a while. One Reaver in particular was tanking me, Fawkes, Dogmeat, a turret, and 3 Sentry Bots simultaneously. I had an M2 .50 cal from a mod and it was still taking a min or so to kill each one of these things. I can't imagine 4 Reavers attacking me at the same time.
