They are under Turret Axis block group. You still need a core for each part, but a rail rocker will lock onto the axis face just like it would a rail. The Bobby AI if I recall has to be on the 'barrel' segment and will automatically move around said axis points up to two degree's of movement deep but no further right now. Otherwise fairly similar to how you used to build turrets.Last time I played, it was when I bought it. My computer broke.
