I'm looking for a system to carry my gun hands free like the gun-bearer, but that will work with a non-hunting pack. Specifically i'm using an arc'teryx naos 70 - here are some pics of the hip belt and shoulder straps. I've been heavily considering a kifaru or stone glacier pack after my last few days out, but the Naos isn't a bad hunting pack - its completely waterproof, has some long pockets on the front, and will carrry a heavy load well enough. Only thing I can't figure out is how to carry my rifle - absolutely hate trying to hike steep ass terrain and side hill deadfall with the sling. The pack does have compression straps but that catches a lot of branches with the rifle up if i'm trying to move through timber. The gun-bearer seems perfect but I watched a video of how it attaches and it needs straps and buckles I don't seem to have. Any other similar systems that allow you to carry hands free?
