Wouldn't lose sleep over govt vs "ultra light" barrel profile on an AR personally
I don't lose sleep over any of it. It was just a preference. If you want to go "light" with an AR, the ultra light barrel profile is necessary. Then there's smaller matters,...like elimination of the front sight on the gas block.
A big part of my choosing the AR was the ability to configure one that's very light. The QRC was the lightest in the base price range at the time.
