Do not buy these, spend a little more money and buy QD swivels from reputable companies like Magpul, BCM, Midwest Industries etc. One swivel works fine and the other one is full of problems. The button is mushy and gets stuck in the depressed position. I sprayed some liquid graphite in it and was able to get it to unlatch. However it won't stay in a QD socket at all, the smallest amount of force will cause it to pop out of the socket, which is very dangerous. Had it pop out of the QD socket twice at the range and nearly dropped my rifle both times but luckily caught it. Only buy these if your going to put it on a cheap rifle that you're not afraid to have potentially dropped, which kind of goes against the whole reason of having a sling in the first place. If you are looking for QD swivels for a duty rifle or any gun you'd depend on with your life then look elsewhere, these will fail when you least expect them to. Buy quality and don't waste your money on these.
