Best i've used - Magpul Industries QD Sling Swivel

When buying something that's supposed to give you positive control of your weapon and give you more mobility, probably a good idea not to go with a no name brand that may fail and cause your sling to fall off your rifle. I've had plenty of cheap "deal" sling swivels and they all were either too lose or failed constantly. With Magpul sling swivels I don't need to worry about my sling failing. When I shoulder my weapon I don't worry about my swivel flying off and my rifle following. Don't buy the cheap deal no name brands on Wish or Amazon buy something reliable.
