Thanks DR, I found an old thread on AR forum, from 2006 where there were multiple post saying it also could be .625″. But I know since then, once S&W came out with the sport2 they made some changes and added the forward assist and dust cover on the ejection port, then went from a 1/7 to a 1/9 twist, so I just want to be sure.
