This is the first govt procured barrel with a low-profile gas block configuration instead of a FSB (NSN: 1005-01-633-2345), note that the journal for a FSB is still present if you wish to install one.
One of the gas block dimples will be exposed if you install a FSB. 2 dimples for gas block set screws are present per the official drawing (spacing .425). The markings on this barrel are also on the gas block journal in front of where the gas block is mounted.
