Chrome-moly barrels have the ability to be highly accurate when broken in properly and are the least expensive of barrel choices... Unlined chrome-moly barrels normally have the shortest life of any material because they experience erosion from bullet friction at a faster rate compared to chrome lined barrels... If used as semi-auto only, this life can still be thousands and thousands of rounds... Plain chrome-moly isnt resistant to corrosion or fouling and is the most difficult to clean... With all of this said, a quality unlined chrome-moly barrel will more than suffice for the average AR15 owner...

Chrome Lined is basically a chrome-moly barrel where the bore and chamber are lined with a thin layer of chrome through an electro-plating process... Chrome lining offers resistance to rust, corrosion, fouling and is easier to clean... Barrel life is also extended when chrome lined...

Lining a chrome-moly barrel with chrome also has the possibility of reducing accuracy... Therefore, a chrome lined barrels is often used more as a work/CQB/SHTF barrel, not as a match/target/competition barrel... Although I have seen some truly excellent accuracy from various chrome lined barrels... MOA can easily be obtained from a quality barrel that is properly chrome line...
