Guess you are referring to the ERPC on the frame. Just for the heck of it I looked for that as far as I could go:
3-15-2011 Company registered by RA arms 870 Remington dr. Madison, N.C.
Under NASDAQ: "Feb 13, 2009 E-RPC is a wholly owned domestic subsidiary to carry out operating activity related to Remington re entering into the handgun market" For some reason they set it up as E-PRC contracted Remington to make the R-1.
