I'm looking for input on sling attachment points for my RA XCR. I picked up a Magpul Rail Sling Attachment and that is good, but I also grabbed a Mapgul ASAP rear sling attachment and it is not compatible with the Dlask adapter/AR stock nut setup. What are you other XCR guys running for a rear sling attachment? I've got a Mapgul MS3 just crying to get hooked up!
