Need help identifying rifle sling

[No.1Nick]

Guys, I have had this rifle sling for probably 20+ years and I desperately would like to buy 1 or 2 more. However I have no idea where I got it or what brand it is. It is really slick! It has spring loaded polycarbonate ends and is extremely durable and quick to change. Can anyone identify it and tell me if it is still available or not?

Thanks, Nick
