Awhile back there was a thread about this sling mount: DD sling mount

Some, myself included, thought it would work better if it would swivel freely since the reciever extension limits rotation and will prevent you sling from twisting itself into a knot.  The first design had the limiters in it.  Just wanted to let anyone interested in these to know that Jay listened to what people said they wanted and made the new ones without the swivel limiters in them.
