Would love to see something not done yet on the Stens, mainly MKII & MKIII, a 45ACP Conversion. Only original 9mm & 7.62 Mauser done by the Chinese! Make an HD 45ACP Barrel threaded for a Suppressor, move the Extractor out for the 45ACP Case Rim, and with 3D Printers maybe make a better Magazine Follower for 45ACP.
Could you sell me the CAD file if it is available? I want to study detail and I am enthusiastic. One of the files that you give me is complete, it included dimensions.
