 Super aggressive serrations. And when I say super aggressive, I mean, this is probably the most aggressive serration I've ever felt. Like, there is zero chance. You cover your hand in gun oil and you can still actuate the slide. I mean, it's super aggressive. The other cool thing that I don't think we've really done a good job of highlighting is, I mean, if you take, everyone puts red dots on their guns now, but when the semi-auto starts to come out of battery and start the recoil cycle, there's always a bit of back spray that comes up.
