Using a multi mount attachment does start to make sense, though, when you look at the economics. An inexpensive rail sling attachment that has a couple attachment options and doesn't weigh significantly more or take up any more space on a rail than a multi mount presents more value than a device that only offers one attachment method. If you end up changing your sling after a few years, not worrying about buying a new mount is worth something.
The Damage Industries Multi Mount reminds me of the VTAC LUSA and the Blue Force Gear Rail Mount Sling Loop. Damage Industries has married the best aspects of these devices while holding the price to $25. The Multi Mount adapts a sling to a 1913 Picatinny rail via a pair of rotation limited QD sockets, HK style or MASH hooks, or slotted directly through the device. It's made in the U.S. of billet aluminum with Mil-A-8625 type III class 2 hardcoat anodizing. The only thing that worries me is running a steel HK or MASH hook through an aluminum fixture. I've seen steel hardware really chew away at aluminum sling attachments over the course of a deployment.
Damage Industries is currently shipping black and dark brown versions and is gauging interest in a FDE version.
