It really sucks that Lichtenberg Researches webpages are no longer available, and most of the pictures and diagrams on AK Files are no longer available from their hosting sites either. I'm about 5 years late to the game on this one unfortunately. I think I am going to have a local machine shop make me a copy of the EOD bolt/Carrier from my x25 blowback build, and use that. I just really want to make sure of my cuts for the 2xtm magwell. Starting with a blank sheet of 4130 .050". It'll be fun either way, but I sure would rather have a complete tutorial with pics.
