Quick detach works too well - Tiger Rock AR-15 End Plate Sling Adapter w/ Quick-Detach Swivel Socket

I tested function with two different QD swivel brands also purchased here on OP; Magpul and Fortis. Neither swivel will insert deep enough to fully lock in. If you twist and pull both swivel brands will disengage, you can visibly see the QD buttons don't pop back up fully when inserted. Both of my swivels work in Fortis, MFT and PSA QD sling mounting points. The other reviews convinced me to go for it despite the too good to be true price. The low price means it probably isn't worth returning so I'll just remove the roughly 1/32" off the face.
