Complete and total pure junk! - Tacfire AR15 Receiver End Plate With Ambi Qd Sling Swivel Attachment

Does not fit any of my quick detach slings. I’ve tried them all absolutely ridiculous this product should not even be sold optics planet sells quality stuff but this is the worst item I purchased.It does slide over the buffer tube and while it is a painful attachment you can attach the castle nut. Poorly engineered only looks good in the picture that is on OpticsPlanet this item should not even be for sale. Buy a strike industries QD it’s much better quality and attach is like a dream.
