I'm also needing to remove the side skirt from my MP5...
I did check out the instructions (if that's what you'd call them) on ugly.net and I found it to be no help at all as they just show you where the clips and fasters are... not how to go about removing them. I was able to remove the two fasteners, but seems the clips are more of a pain. I didn't try using any tools or too much force to avoid breaking them (even though they're cheap to replace).. the more I can spare the better.
Anyone know the technique behind removing them? That'd be swell.
there's screws on the front and the back.... the rest is held on by clips under the side skirt.. if you take them off expect most if not all the clips to break... you will not get the side skirt back on properly if you plan on putting it back on... reason being because you will need to buy new clips
