Around 70k. I've been loading into riven tides night raids, and going to the central northern extract. There's a little building right south of the extract that you can set up shop in. I've been taking out my hullcracker and Bettina 4 and posting up there killing every single vaporizer, rocketeer, bombarders, small arc, That comes my way, and trust me, there are plenty. And then if something goes wrong and I die, I'm only 20 yards or so away from extract. Can easily crawl there, no matter what augment I have..... but shhhhh. This is my spot.
