Tom and all,
What you said will work, of course. Not thinking and needing to change to my stock anyway, I just removed the stock bolt and put it on as you said. Being left handed, I installed mine upside down with the loops to the left and cut a small hole for the sling stud.
Mine is the Beartooth neoprene mentioned above and it helps quieten the hollow plastic stock as I hope it would.
