Me and my brother have been trying to get this done since September of last year and now we are about 90% done on it. I personally have to thank Dan Hallak of Scenario Arms for posting the how to videos to do this.

A mighter box and a drywall saw are hard to use but, My brother pulled it off nicely.

A dremel for touch ups and to smooth the rough parts.

The finished product. As I said, it's about 90% done. I still have to get the adhesive and put my side rails back on.
Any thoughts?
