One of the things I'm confused about it, it sounds like a mil spec tube won't fit a lower that has a commercial fitting.... But I do see people doing this...

I have 4 AR's. CMMG, DPMS, PSA, and a Spikes lower. They will all accept any buffer tubes I have. I also have an adapter to put a AR buffer tube on a Mossberg Shockwave shotgun. It too will accept either a commercial, or mil spec buffer tube.
I have a few commercial, and mil spec buffer tubes. The stocks from commercial and mil spec won't interchange. That's the only difference I've found.
