It might be possible for ADCO or Retro Arms Works to do something to get this to work, but even they might not want to mess with it. Wouldn't hurt to ask though.
Well, that is good information to know. Quite surprising I might add also, considering Colt should be using jigs set up for barrel drilling etc.....
