Verifying Chrome Lined Barrel?

[JustSomeDude]

Just got my upper in from model1sales, and not that I don't trust them, but I want to verify that they sent me the chrome lined barrel and chamber as ordered. Is there a simple and quick way to do this?

Not that I know of but an interesting question.

Usually the barrel is stamped if it is, but don't be too upset if it isn't. As long as you keep your gun clean, the barrel should last for an insane amount of time. I don't have a chrome barrel in my Bushmaster, and i've put over 5000 rounds through it with no signs of wear.

usually with a bore light or any light down the barrel it will look "chrome" but I might not know much about this subject.. just my own experience with my armalite...kc.
