I have attached a gun bearer to mine. Have also strapped my bow to it. You have to add straps as there really aren’t any available. Also, in daypack mode it has a relatively small footprint. Your bow is going to overlap it above, below or off the sides depending on how you rig it. I rigged mine side ways across the top to free up my hands hiking in and hauling meat. It worked fine in pretty open terrain.
I would agree with the post above that within the MR line those 3 packs are probably the most versatile. Pop up is basically a daypack with just enough frame to haul on occasion. The bag fills up quick. The frame works but it isn’t a replacement for a full size hauler if you use it in that role often. It doesn’t have the stability or padding. On the plus side, it is lighter, more compact and cheaper than a full size pack.
