Yeah, most of my shooting suppressed has been at an indoor range, renting their stuff. On the last trip, I had a guy next to me with a short AR that was unsuppressed vs the Mk18 and Surefire RC2 I was shooting. The difference was amazing. His muzzle blast was fairly punishing, even through the separator/baffle. The suppressed Mk18 was nothing in comparison.

The OP asked about 5.56 rifles. If you want really quiet there are many choices and many better than .300BO or 9mm. But that's totally irrelevant.
Back to the OP. Get a Colt 6933 or the same made by someone else of equal quality. Add a surefire RC2 (my favorite) or the equivalent made by someone reputable. Shoot it and be happy.
Don't like the amount of gas you get add a couple of changes as suggested and be totally happy. Shoot tens of thousands of rounds and ride off into the sunset...

The OP also said this, i.e., "inside a residence" and "overall quietness":

I would like an 11.5 barrel. It would be nice to keep the weight down and this rifle has a 50/50 chance to be shot inside a residence. I'm not sure if that means I want less noise at the muzzle or just overall quietness.

I don't exactly follow your point. your saying that the OP wasn't asking about a 5.56 caliber gun? When he said "solely be a 5.56 gun"? I get that your point is that other calibers may be quieter and maybe the OP should check out some options. But that's a whole different topic than the OP started on.

Colt, SOLGW, or Geissele upper (16" for no stamp, 11.5" or 12.5" for a stamp), Dead Air Sandman-S or Nomad-30. Done.

It seems very difficult for me to let any recommendation for dead air products stand without pointing out the huge mess they are currently having and what is apparently very poor customer support. I own a bunch of their stuff bought long ago and its fine but lots of people are not in that position on the newer models.

I went with a PWS Mk111 Pro upper on an Aero Precision lower. Long stroke piston with 3 position AGB on an 11.85” barrel.

No gas in the face with my Recce 5 Mod 3. Even better after upgrading the can to the Eco-flow baffles in the Mod 4. Also good with the lightweight Gen 2 Explorr 224.

I'm with Jon on this. Dead Air is a major nope right now.

Maybe it's time for an actual thread on this since people don't seem to be aware what's going on. I'll start pulling together examples of destroyed Sandman and Sierra 5's.

My plan is suppress my current got to AR which is an 11.5 Daniel Defense on a BCM lower. I got a YHM Turbo 3 on order. I’m going to see how the gun shoot and possibly add a bootlegger BCG to help tune the gas

Not exactly the same thing because I don't have a YHM Turbo3, but my DD 11.5 runs fine with a buffer change and a charging handle replacement.
Me personally I'd probably do the gas tube before I did the BCG.

Something like a BRT gas tube is a very good way to tune. gpbst3 may be looking for more of a "drop-in" solution, in which case parts like the BCG, a buffer, charging handle, and/or a spring would be preferred. I don't know how DD gasses their barrels; hrcjon's buffer and charging handle solution may be all that's needed. As an example: I do use a Bootleg carrier; but in my current rifle, it is only adjusted one position away from full gas. The Noveske barrel is ported nicely, and doesn't require a different tube or much carrier venting. I do have an H3 buffer and Sprinco red spring. It would be fine with a normal carrier, but it doesn't hurt my feelings to vent a bit, and have the ability to turn it up if I want.

In an effort to get back to the OP, I did a brief internet search. I saw Sionics mentioned more than a couple times; I also saw PWS mentioned multiple times. I understand why someone would be hesitant to commit to an "unconventional" gun like the PWS. The Sionics trick is they sell each of their rifles with three different gas port options; whether these are all "off the shelf" (in stock) rifles, or built to order, I don't know. It seems the "off the shelf" silencer-oriented AR is not as easy to come by as it ought to be. Perhaps the market isn't really there, considering the majority of folks in that demographic will build their own.
