I carried an AR-15 in patrol with the 16" barrel as an LEO for years and felt it was near perfection. You get good ballistics from the barrel length and its not so long as to get in the way. If I could have used my Grendel instead of .223 it would have been perfection. The shorter barrels are great if you are going to do building searches and the like but in IMHO the tax stamp and loss of velocity are not worth the shorter barrels and anything longer than 16" tends to get in the way.
