I think they are the same. I just tried an AR 15 gas tube in my DPMS .308 bolt carrier, and it was a tight fit, it certainly couldn't be any bigger. Most online sites don't list them as a separate item. I have one  (.308) coming tomorrow, if they are different, I will post it. Good luck getting any help on this forum.
