You guns are full of it. It most certainly could be made to fit. If Allem could make K80 barrels fit I'm sure someone could make an MX barrel fit a TM receiver. However, it would be costly. So the correctly reply is: it will only fit after extensive work.
If you have a barrel mono block you can have someone make a barrel to fit any gun the problem being the availability of the mono block. However just my opinion.
Put the two side by side and then take a fast guess about just what that would entail. Prolly on par with making a SxS outta an MX8
MX8 and TM1 are entirely different receivers. You may as well try to but the MX8 barely on a Browning Citori.
