My dad and I have been talking about adding an auto of some kind to our collection. He's found an RDIAS at a pretty good price and is willing to finance the buy. He's pretty determined that he wants to use a RRA SBR as a host. This gun has a high shelf, of course. I'm trying to talk him into SBRing a new lower, but I don't think that'll happen.
Is there a shop out there that can mill down the shelf in his lower?
Thanks in advance

FYI, if you go with a new lower as a host, there is no need to SBR it: The RDIAS is a machine gun, and machine guns have no minimum barrel length -- so when the RDIAS is installed, you can put any upper on the host receiver. (Just make sure that if you remove the RDIAS, you also remove any sub-16" uppers at the same time.)
So if you buy a stripped lower and build it up -- say, $150 total -- you won't have to pay any additional taxes, but you will have
two hosts for your sub-16" uppers.
