What happens if I pull the trigger after the M4's clip is empty?

[usmarine]

When I fire the last round and I pull the trigger. What does the bolt (and bolt catch) do?

After the last round, the bolt carrier is held back and you cannot pull the trigger. After you press the bolt catch and release the bolt carrier, you can pull the trigger.

Hey, uh, usmarine, I'm 18 and never seen one and I still knew the answer. Try googleing some of this stuff, eh?

The clip is what you use to load the magazine. The magazine is the box like item protuding from the bottom of the rifle.

 

[too many choices!?]

The M4 has no clip!!!!!

If you fire the last round with the magazine inserted the gun will lock in the open bolt position via the bolt catch. Any subsequent trigger pull(while the bolt is retracted and held open) will not release the hammer(whitch is being held under the the bolt carrier) but will allow the trigger to go through it's forward backward travel. After releasing the bolt carrier(bolt release or charging handle) the hammer will be caught by the trigger sear and you will be able to fire the gun with the trigger again(if it's not on safety ) I second the google comment!!!!! ps to answer your original question ....... they both do absolutely nothing as you pull the trigger with the bolt catch engaged !!!!!!!!!
