Google didn't turn up a whole lot of options. I used a borrowed Urban ERT sling this last weekend for a 3 gun match and really liked it. Only thing that looks like a recipe for disaster in the paracord loop that releases the sling. Would like to find something with a different method that wouldn't be as prone to getting snagged on something. Anything out there that I'm not aware of that may fit the bill? Thanks fellas.

Giving this a bump to see what's out there.

This maybe?

I use the BFG RED swivel on 3 of my ARs and really like it.  I've never had issues with it snagging or releasing when I didn't want it to, but it's instant off when you need it to be.  Two of my shooting buddies thought it was a stupid idea when they first saw one (aesthetics are not its strong suit) but then tried it out and now they have them as well.
