The JAKL 9-SD checks a bunch of boxes for me. But I am curious about what braces/stocks will work with it, what does the end of the receiver when the stock mounts look like. It doesn't look like it is 1913, but I have seen a 1913 adapter. Anyone have one that they share some info about.

The back of the receiver itself is basically like any AR type lower with the threads for the buffer extension.  There's various things that attach to the lower there and match up the lines of the upper.

There is the 1913 rail end cap.  https://palmettostatearmory.com/psa-jakl-9mm-brace-stock-adapter-thread-plug-and-screw-retail-sku.html

Otherwise the various stocks/braces made just for JAKLs are like that part, but with the stock/brace and sometimes a hinge built in instead of a rail.
