It would be extremely stupid for anybody to keep a bayonet on their musket/rifle at all times. In fact, the only time soldiers really attach bayonets nowadays is during military drill and performances (like the Trooping of the Clours).

But a bit more on subject, I suspect the idea of creating two separate models (one with bayonet and one without) which serve exactly the same purpose seemed a little pointless to Ubisoft.
