I actually just thought about this with the -M I just got.
To be honest, I don't understand why RA is still doing this. It'd be a lot cheaper to make this uppers without side/bottom rails, as, that would reduce a lot of extra machine time. Just put a few holes in for mounting rails up near the front and you're good to go.
I'm curious if it has to do with rigidity and the way the quick change barrel setup works.

Mounting a light under the rifles is bad but to each his own
No it can't help the slots in the rail are as deep as the shave
How is it bad?
