ah ok, was thinking he just wanted to put a plug in for BHW, I was thinking he meant that, but i went there and couldn't find any info, I know that ARP makes their own forearms called the Skip Flute Rail, he machines them and had posts up from the design to completion. I think I remember them going with a different upper, there are several parts they've changed vendors on, but does not make his own uppers and doesn't offer a 'steel railed upper', so maybe he could post a link
