I recently picked up a DPMS Predator. After I gave it a full cleaning I noticed something weird on the crown, and I can't decide if it's chrome lined or just damaged.
The reason I think it might be lined are:
- There appears to be some chrome spillage over the crown..?
- I cleaned it thouroughly with Barnes CR-10 & there was no blue whatsoever on any patch. I have never seen this before.
- There's a chrome-ish look at the edge of the crown.
- There's also a chrome-esque look to the internal bore of the gas port in the bolt.
The reason I think it might not be lined are:
- The barrel is not stamped "chrome".
- from one angle it looks like the crown might just be cut crooked?
Here's a photo from one side-
And here's a photo when I turn the barrel 180°-
So, what do you guys think? If it's not lined, I'm going to get a PTG crowning tool & clean it up. If it is lined apparently I can't do that, and I'll have to live with the weird cut in the crown.
