Thanks guys.
Bob the Angry Potato - I have pics of it without the magwell but it is in stock form. The comp is uses a little adapter that attaches to an extended inner barrel and is secured to the inner barrel with set screws. Then the comp itself just screws onto the threaded inner barrel attachment and the comp is held stable with a set screw. I got both the comp and the inner barrel attachment from
www.X-Fire.org.
ILLusion - I polished the side of the comp with 800 grit sandpaper and a small block of wood.
