Anyone gave a solution for mounting RS RIS barrel nuts? I'm fitting a 12" MI RIS and the barrel nut it too tight. I am going to sand the paint off the receiver barrel screw with my dremel & try again...

any tricks to making it snug enough to avoid problems with the bolt catch? I've been lurking this forum for acouple weeks, prior to picking up the CQBR today, and I know that you are the SOPMOD expert Richard, so your help is appreciated

Anyone have a gearbox picture of a front wired sopmod? I'm converting my CQBR to a front wired PEQ, and trying to figure out how to run the wires. Thanks
