[Any opinions on Midwest Industries M4 MLOK Rail]

Who made the head shield?  I've been searching in the forum and no on even mention what brand or where they got it from.

It feels solid, but I have only taken it out to shoot once. 

I was able to leave it on when I disassembled it to change out my recoil tube, just loosened the bottom brass set screws.
