Can someone tell me why I should get one type barrel over the other, considering all other aspects being equal? Im talking specifically about BCM 16 inch and 14.5 inch barrels. I understand the raw differences between them, but I'm not sure, for instance, what benefits a Cold hammer forged would have over the standard. Are BFH worth the extra money? Are they heavier? Are the light weight barrels less accurate? How much lighter are they? Why not just stick with a BCM standard?
