Bought these to fit onto an extra-wide Tab Gear Biathlon sling.....they work just fine and attach perfectly into my qd cups
The most durable swivel set I have ! Perfect size to fit and attach my Viking Tactics 2 point sling !!
Works as intended. Works just as well as my formerly government issued QD swivels with no failures. I have it on my carbine locked to my trunk lid. It takes a beating there. I yank on the strap to close my trunk (several times per day). Take it on hikes thru the woods when I'm not working. I can rely on these swivels.
