Has anyone else tried one of these yet? The quality is simply outstanding with rock solid lock up. The price was surprising. I would say these even surpass the KAC M4 RAS as both the top and bottom rail lock into the barrel nut as opposed to only the top on the KAC. I don’t have many non FF railed carbines anymore, but these are going on the several I still do own.
