It would be quicker to list all the types of sling hardware that you can’t attach to the new Damage Industries Multi Mount Sling Mount (MMSM). It would be a very short list.
The MMSM has 4 different places to attach a sling and is designed to work with all common sling attachment hardware. It can threaded with your typical webbing sling ends. It accepts QD sling swivels in two different locations (rotation limited) and it has a small loop for using hardware like MASH Hooks and Snap Hooks.
Even with all of that functionality, it still consists of only 2 pieces. It looks to be an incredibly simple yet functional piece of gear.
