Marking under the handguard is "1B13BA OA-M4AH16C 5.56 NATO 1/7".
"MP" stamped near the 203 groove.
16", M4 profile, carbine gas system, appears to be Melonite treated, 0.068" gas port size (via caliper). Who makes this barrel?

Help me out, I was curious and did try to use google, couldn't find it using 1B13BA or the whole inscription.
Patriotism means to stand by the country. It does not mean to stand by the President... - Theodore Roosevelt, Lincoln and Free Speech, Metropolitan Magazine, Volume 47, Number 6, May 1918.
Every Communist must grasp the truth. Political power grows out of the barrel of a gun. Our principle is that the Party commands the gun, and the gun must never be allowed to command the Party Mao Zedong, 6 November, 1938 - speech to the Communist Patry of China's sixth Central Committee
