Steve Rinella's sling is made by me at my company RipCordSurvival.com . I started out making bracelets for deployed soldiers as a gift. My pal who was deployed told me to make something more of it. RipCordSurvival was born shortly after. David Amick of Carolina Custom Rifles found me and asked if I could make a sling for a custom rifle that is unlike any other. After brainstorming together, my first sling went onto Steves's 7mm in a fateful twist. I have since innovated on the design, but the platform remains unchanged. I know this is an old post, but I thought I'd throw it out here. I'll give you a discount if you're interested in purchasing one.
