I thought the 45ACP uppers run just on a blow-back design like the 9mm uppers. No gas system, no locking bolt.
So moving on....
These upper pics are with an AR-15 lower receiver which I need to run an adapter to accept Uzi mag, I was just showing that for the purpose of knowing how I started this lower project.
This will take the place of the standard lower and allow it to accept Grease gun mags.
My 45ACP is direct impingement.
