There are two ways to answer this question.  Yes, its supposed to do that when the firing pin isn't there for it to hit (when the upper is off).  Second, no, never let the hammer hit the lower and the catch without the upper in place.  Put your thumb over the hammer and lower it to let it fall, and never let it hit the lower without the upper in place.  Damage from this, my friend, sucks big time.

I have a thick piece of truck tire iner-tube that I cut a small chunk out of and place over the bolt release and down into the tigger portion of the lower when installing triggers so I can give a quick test/feel check before fully assembling.  Saves on bruised left thumbs.

To say nothing of broken lower reciever webs[:D].

The only actual broken lower AR reciever I've ever seen was exactly at that point.  That was about 1965, before I ever owned an AR, and taught me a lesson I've never forgotten[:D]

You'll break the bolt catch with the hammer free falling. The top section will break off. I replaced one for a fella once.
