RRA Barrels

[Hoser23]

Are the standard barrels offered by Rock River Arms chrome-lined, or is this an option?

[Bio-Hazard]

It appears to be an option right now. I ordered a RRA complete 16"CAR upper the Friday before last. I heard it was gonna be a pretty good wait. I didn't see the option before on their website when I placed my order, but now it's there. I'm gonna call tomorrow and see if I can upgrade. I imagine they haven't gotten anywhere close to starting my build yet. How much can a chrome lining improve the wear quality of a barrel and chamber throat? Is there much of a difference?
