My barrel has been shooting pretty bad lately, 6.5 Grendel 16”. So I broke it down today, was going to clean up the receiver face and see if maybe that would help. As I was cleaning up the carbon on the crown of it, I noticed these gouges just inside. Anyone see this before? I didn’t pay attention to it when I got it new and have no idea how I would’ve done this. Any insight would be appreciated!

No, but if you had some hard debris like tiny rock pebbles enter the barrel after a shooting session or stuck on a jag/swab, I could see that happening. But those similar looking nicks and gouge marks on the "face" of the crown outside the bore might be telling a different story. Has the barrel ever been dropped or come in contact with the ground without a muzzle device? And what type of tool(s) are you using to remove/install the muzzle device?
Did you use brass (or bronze), a bore snake and a carbon fiber rod to clean the crown?
Although its hard to determine from one picture it appears that the damage was not from regular barrel cleaning, but from the attempt to remove the carbon from the crown after taking the muzzle device off. The gouges are clearly through a surface layer of carbon and into the steel.
On the other hand, you might have two unrelated things going on, however. Some of the damage inside the bore could be a form of pitting from corrosion.
