Just bought a RRA Upper and barrel. it's a 16" M4 style barrel. How can I tell if the barrel is chrome lined? When I bought it from a local dealer I never thought to ask! And, if it's not...what is the disadvantage.

The RRA barrel has no markings I can see anyplace on the barrel

Look on top of the chamber on the barrel under the gas tube.

What does it say?

Is there a silver ring around the chamber?

With a clean bore the chrome bore will look a bit frosty as opposed to the plain barrel which should look bright and shiny... Remember that this is industrial hard chrome that we're talking about, so it won't shine like decorative chrome plating...

Just in case you cant find any markings on the barrel...
