I will probably end up just having my machinist/ tool and die maker buddy who I trust and is fully competent set up the barrel and gas block on his Bridgeport mill. Then he can just lightly spot the drilling area on the gas block with a .125" inch carbide two flute end mill to break through the melonite finish and drill them. I will just have to buy a #2/0 reamer from Brownells or Midway for around $20 so he can fit the taper pin I got from Bravo Co. Having done a lot of machinist type work myself in the past, I can tell you it is not a difficult job *if *you have the right machine tools and experience. If you do not have the tools or experience (drilling and reaming) it can easily lead to a not so good outcome.
