Doesn't work for me. - Midwest Industries Quick Detach End Plate Sling Adapter

The sling adapter is easy to install and locks up solid. The downside, for me, is that the QD cup does not have any sort of anti rotation groves. I tried to use it for a year, really wanting to like it. But, every time I try to sling or remove the weapon, the sling twists and I have to stop and straighten it out. Mounted it on a SHTF weapon and It's simply not going to work.
