20" colt HBAR barrel

[Riflehunter1776]

looking for a lightly used 20" heavy contour barrel, colt mfg, chrome lined with standard front sight assembly. Brownells had them only a few months ago, but I did not see it until too late. I'm trying to restore a green label to the correct configuration.

(for reference, this is what I'm looking for)
