So in theory a flat top upper with m4 feedramps would not work with the barrel then. Or am I over thinking this. This seemed to have a pretty good explanation. ww w.ar15.com/archive/topic.html?b=3&f=118&t=506552
Basically I would like to replace the fixed upper with a flat top one and most flat top uppers have the m4 cuts.
