I believe the sizes are reversed. Go to the Vltor site and read the FAQ about how to determine your tube.

I bought an EMOD this weekend and it fits and feels great. HAven't shot with it yet. It is about an inch longer than my CAA stock it replaced.

The poster above is correct. Mil-spec receiver extensions are smaller than commercial models. Unless something has changed recently, RRA uses commercial extensions.

Other way around. Here is a good source from Magpul: http://www.magpul.com/pdfs/technotes/ctr/buffertubeid.pdf

RRA uses a commercial RE.
