On the actual military weapons (whether they have the M4 profile barrel or the government profile barrel), the barrel length is 14.5 inches. On civilian "M-forgeries", a 16 inch barrel is more commonplace, although the 14.5 inch barrels can be found on the civil market, provided that they are equipped with a permanently mounted flash suppressor or muzzle brake of a sort which brings the overall barrel length to 16".
