My barrel looks very similar to the one in the picture except for the HF, for hammer forged. Not having the HF marking, does that preclude my barrel from being a BMC?
No, not all barrels from BCM are hammer forged. You got me curious about my BCM uppers so I went and checked the markings. My Bravo that isn't hammer forged is marked HP MP. The one that is hammer forged is marked BFH HP MP.
