Works well; possible quality control issues - Tiger Rock AR-15 End Plate Sling Adapter w/ Quick-Detach Swivel Socket

Once I installed it properly, it works perfectly. It holds a QD aling mount just fine. Swivel swivels nice and smoothly and doesnt come out... Unless you habe it on the wrong side. Only reason why I couldnt put 5 stars is because, on one side, the swivel will not fit. I was under the understanding that it doesnt matter which side you use, so i installed it, then realized i the qd would slip out. But after reinstalling and spinning it to the other side, it works great.
