Ok this guy has made a co-axial piston gun and after reading it I have a few questions that I know spudfiles can answer. He said that due to this complex design the piston is in front, how is this possible? What size chamber and barrel? Do you think that he just did the bolt-action on the at-4 tube in the video for looks (because he was recording).

Thanks,

(Update: The latest version went back to a rear-piston design for serviceability.)

clearly it wasn't a good idea
