The safety detent is under the grip on the AR15 as well. And yes you need to install the safety before you tighten the set screws. You do not need the tool. The castle nut will not need to come off. If you have anti walk or anti roll pins you do not need to tighten the set screws. That is the main reason for them. To put pressure on the pins. But I still do just to be sure it won't move.
You’re correct. My bad. The takedown pin detent is behind the end plate on the AR15. It’s been a while since I’ve worked on the smaller frame stuff just took a look at a stripped one I have.
So just the grip has to come off to remove the spring and detent for the safety.
