Why are the gas systems crossed....
Each gun operates the other. Shoot the bottom gun and it cycles the top gun. Note that the bottom gun has FA, I'll assume the top gun has FA as well. When you shoot the bottom gun and cycle the top, if the trigger of the top gun is strapped down on FA you will then fire the top gun and cycle the bottom one. This will go back and forth until you release the bottom gun's trigger. On SA you should get a two burst with the top gun's trigger strapped down.

I'll take the drum mags. You can melt the rest and put it out of its (and our) misery!
IIRC the top receiver is just a slave. The bottom gun fires, cycling the top gun which fires, reloading the bottom.
Tony has tried some neat stuff.
Bubba should be banned.
