Colt 9mm AR barrel, 10.5", threaded 1/2x36, marked "0" on taper near chamber, what looks to be 2/99 near handguard cap, barrel marked C MP CB (from what I've researched mean Colt Magnetic Particle Tested Chromed Bore) and 9MM, front sight base is marked "C" on site post area and "3" on gas tube area. has a small hex piece in gas block to keep handguards from moving.
unknown round count as i purchased this used but it shoots very well, no issues, have shot with a suppressor on it with no issues either. chamber and bore look very good.
