Does anyone know if they make a blowback kit for the TM Thompson SMG. I have seen one on youtube.com but I do not know if that was a custom job only or if there is a kit I can buy?
This one is a modification. He even tells you how to do it.
more information about that mod from the video,I just looked at it, makes me a little nervous about how long the piston will last with that mod,it looked like its will crack apart eventually.
