Uzi Caliber conversion

[colossians323]

My searchenginefu is weak.
I have a RR blocking bar removed 45ACP SMG (action arms IMI NIB)

To convert to a 9mm is all that is needed is a full auto 9mm bolt and barrel, or does the grip need to be changed out too?

Thanks in advance for your answer(s)

Your grip frame should be fine if it's not a Grease Magazine gun lower. Bottom line is if you can insert 9mm mags into it and they lock up you are good GG mags are larger in size so a 9mm mag would fit sloppy
