Really depends on what I'm using the rifle for. I have a 9mm PCC with a 14.5" JP Supermatch barrel and JP comp, because that's a pure competition rifle and isn't getting suppressed. If it's something more tactical/defensive/etc., I would probably pin a SiCo ASR FH or brake so I could use my can. I could also see pinning in a VG6 Epsilon or Gamma (my favorite budget muzzle devices when I want a brake/comp).
Let's put it this way. If your join date was somewhere in 2020, most people here might be left with the impression you were on a fishing expedition. Your questions were a bit...leading, shall we say.
This is generally how I do business, but I admit that I will probably be buying a general purpose 16" 5.56 upper just because it is getting somewhat annoying to constantly bug the ATF a few weeks in advance every time I want to go out of state to a different location than usual. (I file something like 20 5320.20s a year to cover various pieces of my collection going to various places ahead of time, and I STILL find that I have to file another from time to time.)
