No a 144 stuffer is not a direct fit into the 155. About an hour of fitting and grinding little by little with a dremel i was able to fit a 144 tbm into my oem 155 nicely. Its easily done.

Interesting. Is it the bore for the sleeve, the vein grooves, or length that need massaging?
I guess what all did you grind? Thanks for the info.

It was a couple years ago but if i remember correctly it was the thickness of each vein needed to be widened slightly. Also the bore at the front needed to be a bit larger it think.
