Sling swivel - Troy Q.D. 360 Push Button Sling Mount, w/Heavy Duty 360 desgrees Push Button Swivel

I got this because I had no where to mount my sling on my quad rail. Turns out that all I needed was the actual swivel because it fits into one of the holes in the quad rail, so the actual mount part I didn't use, I'll just use it on another build though. Really easy to use. It was kinda sketchy at first because I thought it would come out but it actually holds really well and you really have to push the button for it to come out. Even holds during transition drills when I pretty much throw my rifle across my body.
