Sheet Metal Lower AR-15/AR-45ACP Build

[ARBuilder]

Hi All
I am doing a sheet metal lower 45 ACP build.
I will be using a Grease Gun Mag when it is all said and done.
Yes it WILL be HEAVY
Yes it WILL be UGLY
Yes YOU CAN BUILD IT with HAND TOOLS!
Yes you can build it to AR-15 mag specs!

First is to cut out the FCG pieces

Here is a few more pcs.

Time for some welding.

This is where I stopped tonight after 2 hours of work, I will get this going again this week.

[ARBuilder]

I will continue as the week goes!!!

[ARBuilder]

I guess I should show the build as it started.
So here is a glimpse

more pics and changes.....

At this point I realized I needed to make my own gas block out of aluminum

[ARBuilder]

And at this point it fires fine but with mag issues

[ARBuilder]

it is buffer-less system

[ARBuilder]

I turned down the rear of the carrier so it goes over the buffer spring and will leave it at that for now

I have to meet you some day! Your work blows me away.

Ok so where did the sheet metal lower go?

I thought the 45ACP uppers run just on a blow-back design like the 9mm uppers. No gas system, no locking bolt.
