@markm - so a .30cal K is preferred to a 5.56 K for a 5.56 gun?

Depends who you ask. If I were buying a can for one of my ARs, I would certainly be getting a light weight 30 cal K can that directly threads to the barrel.
Generally speaking, Back pressure is lower, weight is lower, and port snap is lower.
In the early days of AAC and Gemtech, everyone wanted "full-auto" rated cans with the lowed Db ratings. Two of the WORST things you could want because you get a HEAVY can with massive back pressure. The m4-2000 for example. They're miserably heavy cans that have terrible back pressure. Compared to modern selections, those things are terrible on an AR.

On quieter at ear equaling louder at the muzzle, I’m not convinced. I own a pile of rifle silencers and have used another pile. I’m certain that it is true sometimes, particularly with un-tuned hosts or older cans with more extreme bias. However, I’ve seen metering videos that used legit meters in which cans that differed only in bore diameter (exceedingly rare) on factory Colt 16” and 10.5” rifles in which there was little or no difference at the ear, but the smaller bore can performed much, much better at the muzzle. I’ve also noticed that in my experience cans that are really good at the ear are also frequently good at the muzzle, and even more so on a tuned host. And that makes sense, given that sound intensity degrades at the square of the distance and that the ear is roughy the same distance from the muzzle as the muzzle mic is to the muzzle. This effect is, of course, manipulable via test barrel length.
Truth is, the real reason 7.62 cans usually sound better or same to the shooter in comparison to similar 5.56 cans is that they are significantly longer.
For the OP….depends. Lol.
Dwell time, gassing, barrel, and ammo are a factor too. I've had adjustable gas block set ups that ran perfectly, but the port snap was painful for me, the shooter. I had to dump the set up because if I have to wear ears, there's no point in the ass aches of dirty suppression.
The first time I shot a mini can, I expected it to hurt my ears, but the lower back pressure actually made the shooter's position quite enjoyable. Another small can we shoot is the mini KAC 5.56 can. It's got like 3 baffles. It's fairly quiet at the shooting position, but barky for the other guys spotting for the shooter.
The Dead Air and YHM K type cans with changeable thread adapters are my favorites. I think Pappabear said he wished he had all Dead Air direct threads. They're light and as quiet as the humongous 30 cal cans with twice the baffles.

Well,
What's a good K-type suppressor for my 580+ series 16 in Mini-14?
I don't want long or heavy. Doesn't need to be hearing safe. Needs to have minimal gas face.
The YHM Turbo K is on my want list. Fairly cheap. I think Clint here from Black River Tactical has said good things about them. I've grown to hate suppressors on gas guns, but the YHM can has me willing to give it another go.
