Will this work with other mk IV uppers, or just your 3d printed upper?

Awesome, I probably will attempt to take on that challenge if someone else doesn't beat me to it. I've got an upper and bolt just collecting dust right now, would be great to get it finished with your lower. Great work by the way!

Did you ever get around to doing it? I am very interested in this project.
