Reload Animation Glitch

[the_law]

So I recently got a copy of CoD MW2, and I decided to experiment with importing some of its weapons and animations to CoD2.
Although I had to modify the viewhands, I managed to get it mostly working.

However, as you can see in the video, there is a little glitch with the reload animations. I suspect that this has something to do the the meshes of the clip/bolt.
Anyone have a possible explanation to this glitch? I can upload all my source files if you want.

Side note: In the models I get from Lime, the meshes are invisible but the Hypergraph says they are still there. Can someone see if the same problem exists when using the MA file in Maya 8.5? I use NotePad to edit the MA in order to open it in Maya 6.0.
