Evidence suggests that Colt does not use 4150 steel in AR-15 rifle barrels, and never has.

Their are a couple of companies that are having 1/7 chrome lined 4150 barrels made in different configurations. The ones that come to mind;

Global Tactical
Bravo Company
CMMG

Not sure if their are more or not, just go over to arfcom and do some looking.
