I don't have access to a milling machine, it was done by hand & eye. I used needle files, a drill bit held by hand for the rear slide hole, and my dremel with a tiny engraving bit to start the notch in the bbu.
I've only fired a handful of rounds through it so far since this was done, so I can't for certain state any vast improvement performance wise, except the bbu doesn't get loose and wobble around like the original one did.
