    I was gonna say that MAYBE there was a height variation between the upper reciever and the forward rail system. But then it was carry over because the upper rail mounts to both.

    Maybe it's a shooter's preference because it raises the height overall before placing an optic?

    Or maybe if the front end if free float, it helps hold the zero of the scope incase the free float some how rotates?
