Don't know your budget but Wilson Combat has 6.5 Grendel 22" barreled ARs. I have their 20" Grendel barrel on my home built AR & it's a good shooter. My only experience with the three possibilities you mentioned are with a BCA upper. It wasn't a good experience. I had to shim the barrel extension on a 6.5 Grendel Odin barrel with .002" shim stock to get a tight barrel/upper fit. The combo never shot well...
