ok I get it, same name but different products. Sorry I guess I hid the link in the earlier message. This isn't made by eberlestock. It's definitely worth a look before you buy anything.
Gunslinger home of the worlds first compact rifle holster,Hunting and fishing info
It is a multi-piece harness system. There is a belt piece with a hook that mounts to the belt strap on your pack. Then there is a strap that attaches to the opposite shoulder strap and connects with your rifle sling to keep pressure on the rifle to hold it in place. I havent got a chance to take it hunting yet, but I strapped my 700 to it and jumped around my house with it. I looked ridiculous, but it held strong until the woman made me stop.
I'm kinda short and stocky so the scabbard was a waste of money for me. My arm just isn't long enough to draw the rifle out of the scabbard while it was mounted to my backpack. I still have it but it justs sits in the closet. It works ok when its not on the pack, but that's how I hunt mainly so......
