Great piece on a new product. I don't currently own a gun but that is one I might someday. I respect others rights tp voice opposition to guns but am big on our birth-right in this country to responsibly own guns. I commend you on keeping this site well rounded in the ultralight realm.
Also, the idea of hunting "only" in a survival situation is silly and probably ineffective if you have no hunting training. Hunting is an outdoor art, as is fly fishing and ultralight packing and requires lots of practice, learning, mentors, proper gear and strategies. Ultralight gear and strategies of any genre is appropriately discussed here if used responsibly in the outdoors.
In keeping with that idea, I'd like to suggest experts on living off the land to contribute more ideas on this site for foraging and preparing, roots, nuts, seeds, leaves, berries, birds, animals, fish etc. that can be found in ultralight backpacking areas.
I had a watercress salad once with smashed wild raspberry dressing that was amazing! I once shot a ptarmigan during an Alaskan packraft trip and it made a great meal on a bed of Rice-A-Roni. I made willow bark tea once to help calm a toothache. I love any and all self-sufficient skills that can add flair, skill and dimension to an otherwise average outing.
I'm all for learning the modern versions of aboriginal skills and gear, not just how to get from A-B as light and quick as possible. Keep up the great work!
