Newbie here.  Notices EA Lowers are differentiated as Low Shelf or Hi Shelf.  Can someone explain the difference?

High shelf means you cannot use a RDIAS, while you can with a Low shelf. The lowers are basically the same, but high shelf lowers have more metal in the rear take down pin area in order to block somebody from installing a registered drop in auto sear to convert it to full-auto.
