Steve, I saw that, thanks for posting. I was thinking it was an m2 barrel but according to the 2006 catalog, an SBS m2 wasn't an option which had me stumped. An M1 barrel makes more sense, although this barrel has the shoulder stop which I don't think was introduced until a few years after 2006. Anyway, mystery solved and thanks for all the comments.

I have this 2006 M2 Tactical with an 18.5 barrel, it's not a crio barrel and has a fixed choke. The factory ghost ring sights are installed but the setback on the front is farther back than I've seen on others. Has anyone seen a barrel with the front sight set this far back? It almost looks like it is positioned for a 14" SBS barrel.
