These are excellent swivels if you use your sling for stability during shooting. The rounded edges eliminate any sharp edges from digging into your hand if you have it up tight next to the swivel. The quick disconnect is quick and easy, allowing you to keep the sling on your arm if you want. The only way these could be better is if they were made from stainless steel.
Pros: Rounded Corners, Quick Disconnect
Cons: None
