How do I attach a sling swivel to an Oryx chassis? I have been using a bipod attached to a short pic rail connected to the Mlok slots, but I want to try using a shooting sling for prone. I'm really clueless about swivels. 
There is a small hole forward of the Mlok slots on the forend. It apppears to be threaded or maybe just concentric grooves? The MDT website has a threaded stud with a sideways hole but then I need the ring. Some websites have a push button stud with what looks like ball detents that includes a ring. I would really appreciate advice on what to get.
