A moderator on a 223 can block out the noise from the muzzle blast but cannot stop the noise from breaking the sound barrier.

Most manufacturers say that a moderator on a 223 will take it down to the noise of an unsuppressed 22lr.

But if you were to reload your own subsonic 223 ammo that will not break the sound barrier then it will be like the movies. But by doing this you will have terrible ballistics from your loads, and have trouble because the case is using about 4grains of powder instead of around 27grains.

You can on the other hand by uppers/barrels designed for a subsonic calibre like the 300whisper, but this wont have terribly great ballistics either.

So yes, you can completely silence a 223 but it may not be what you are wanting.
