Colt rifles have never came with a jeweled moving parts assembly.
There could have been some engineering prototype made like this but I have never seen one.
A chrome moving parts assembly was used due to the slickness of the chrome and was though to provide some of the benifits of lubrication.
Parkerizing holds lube better and it was discovered the chrome was not needed.
It has no effect on reliability either way.
