As a Gunbearer owner I've never loved the shoulder attachment. I've also tried the Talarik Sling Hook and one other brand I can't remember the name of. They always feel like they aren't secure enough, are in the way, or hurt more than they help. The Slik 3 looks really nice but I can't get over its weight, which that metal bar in the bottom rest is probably half of. I just pinged them because they don't post an official number and they said it's 13 ounces. Shoot, my BTR glassing stool is 16 and I was thrilled to get it down to that. Are y'all really rolling with a rifle carrier that weighs that much?
I felt the same way. I just would not carry a rifle sling that weighs that much. That is why I use the GB cradle with the SLIK SLING top strap. I REALLY like the SLIK SLING top strap. That GB cradle can be easily modified to fit other belts, nearly anything.
