I just started breaking in my XCR Light tonight, fired 60 rounds. I noticed after firing that the barrel seems slightly gray-ish, as in it seems to have changed coloration. Is this an issue I should be concerned with? This seems to be an amaturish question to me, but I have never noticed this with any issue M4s I have worked with.

My barrel never changed colour. Maybe it was oil drying and revealing the parkerized colour?

normal.

wipe it down with some oil and it should look like it did before.

ditto. If ya want it sleek and black, oil her up.

I didn't really think it was a problem, just wanted to check and be sure. Thanks all.

I ran a suppressor on my 16" bbl. and it discolored after a while. All the oil in the world wouldn't get it back to it's original color. I really don't care because my guns are tools and I run them hard. none of them are safe queens. ;D
