Well, this sucks... sorry to everybody for going over this again..
But I emailed Rob Arms tech support for the official word and asked them specifically if the XCR-L can handle 5.56 NATO, and what kind of chamber it has. They didn't bother to respond to me. I know on their page that it says 5.56 NATO (223 remington) but the two are not equivalent but it looks like they are saying it is.
Anyways, sorry to keep bringing this up.
