Anyone have trouble with the short barrel (10.5) 607s cycling?  I've heard roomers of trouble with some of the short barrels.  If there is anything I need to do in the build process to prevent cycling issues, I'd like to know.  Any tips would be appreciated.

I don't have a 607, but my 10" and 10.5" SBR uppers are configured like uxb's and I haven't had a problem yet...
