My friend would like to scale down to 4.5 mm with his 5.5 mm FX cutlass, but i am having a hard time finding a way to do that outside of contracting a gun smith, and with the charge of one of those here it would be cheaper to just buy a new gun then.

Any of you fine gentlemen that have a angle to thin i can try ?

I would assume like anything else it would take a new barrel and a new feed probe, and with this old stuff maybe a new hammer spring / hammer.
