Update: Works. Limited testing, but it might be a little light, as my buffer got stuck in the arm. Didn't really notice when it happened, so it may not even be 100% necessary...
I have been spoiled by the Urutau's method of bolt construction. I had a Partisan-9 that was collecting dust with no bolt, so I got to work on this. Do note, this is untested, but I'm looking forward to testing soon.
