Does Anyone Sell An AR 45 Conversion that takes Thompson Mags?

[Tartakovsky]

I have a Thompson Semi Auto M1921 and as such, have a bunch of pre-ban 30 rd Mags. I’d like to get an AR-45 conversion as I also have a few ARs and would love to shoot one as a PCC. Anyone know of a supplier for a kit to convert to 45 that takes these Mags?

That's a good question, I'd also like to have an AR chambered in .45 acp., even if it takes Glock or M3 Grease Gun mags. I know it's possible to make them because you can already get an AR upper chambered in .50 Beowulf.

Unfortunately, disclaimer, these AR45s use unmodified grease gun mags, but this was the best I could find:
