Similar to, but much better than, the magpul mag543 - Strike Industries Quick Detach Sling Swivel Loop

Bought both the Magpul MAG543 and the Strike Industries Standard QD mounts and used each on opposite ends of my sling. The Magpul requires steadying the QD by pulling on the sling behind the mount or applying steady pressure opposite where the sling is attached in order to perform the squeeze-and-push-to-disengage action to remove the QD. The Strike Industries version uses a simpler squeeze-only action to remove the QD. I feel it's simpler, faster, and more intuitive than the Magpul equivalent QD. YMMV.
