Kimio, with the scanner and good milling devices one could replicate just about any part of any firearm new or old, or all the parts to build a complete firearm except the springs.
There is so much potential to this laser scanner stuff. Someone on the internet probably already has a laser scanner and is compiling a library of laser scans of individual gun parts. This way you don't need a laser scanner to get all of the information you need to mill all the parts of a 1911, you just pay them for the scans.
Its the future of machining, and the whole process is simple enough that you no longer need to be a master machinist to remake just about any part. I think it will spur on a cottage industry, as its something you could do in your garage.
