I’ve used the K gunbearer a lot. I think it take some getting used to, but it sure is handy. I will comment on one downside. If you are a guided hunter (as I have been) and you are following around a super fit hunting guide, the time it take to put it and take it out of the gunbearer will let the guide get out of sight before you have taken a step. AND going uphill, it’s hard to keep the rifle barrel from swishing back and forth in front of your face. I usually end up putting the butt in a side pocket and using the side straps
