So I read an article in an old copy of Small Arms Review (SAR) that mentioned various conversions for the Mac-10 line of submachine-guns to run .22LR. One even ran off 10/22 magazines.
- Circa Q1 2020, considering the price of bulk 9㎜ Parabellum ammo, is this worth the bother? Particularly in light that I plan installing a Lage upper once they will sell me one. (Many months in and still nothing.)
- If the answer is affirmative, which one?
