Im stuck on a problem with moving something

Im working with an older template and am using cs4. There is just one tiny section I am stumped on.

I just cant seem to figure out how the tween is made so I can move it to a new location. It is hard to explain.

The site is clanratedx.com

The part I am trying to move is almost non detectable. If you look at the barrell of the person on the left you sill see some very small smoke coming from the barrell of the machine gun. I am trying to move it to the barrel of the pistol. It is made up of about 20 layers and is configured in a way I am just stumped. Is there any reading that might shed some light on the subject. I have only been working with flash for about a week now and am usually able to figure most things out.
