A single piece of brass needs to be super glued into the half of the barrel with the O-ring. Slide on the other part, and match it up to the cut you made earlier. Super glue that seam. Now, just take out your dremel and cut off all the stuff that is not on the orange of the breach. Make sure you smooth out all the cuts with a small fine file or your darts will be eaten.
Here is the brass already cut in the back part.

And I sanded part of the jam door like I saw in an auction on ebay:

I just removed these pieces, so now you can un-cock your gun when it's pulled back to avoid a dry fire. Not sure what else that did.

And here it is finished:
