I'd really like to get a QD socket that would somehow work with an MP5 stock so I can run it with a MS4 style sling. I run a TW5 for CQB, currently I have a simple one point sling attached to the MP5 style stock sling mounting bar using a split ring. Its not glamorous at all. I thought there might be a stock screw/pin with a QD socket, but I can't seem to find exactly what I'm looking for. Recommendations appreciated.
