    I was browsing their website it shows all their 14.5" M4 barrels feature 1x9 Chrome-lined barrels. I emailed them a week ago and have not received an answer. Any help here? Thanks.

    edit:

    the barrel reads: B MP 5.56 NATO 1/9

    if memory serves me right, the "B" stands for "chrome bore", Is this correct?

    one way you can verify that a barrel is chrome-lined is to simply look at the chamber.. if you see a ring of light gray surrounded by darker gray or black, that's chroming extending out of the chamber.

    just because you dont see chrome there doesn't mean it's not chromed, however- some manufacturers chrome their bores, but not their chambers.
