I like the Gunbearer and usually always add it to a Kifaru or other packs. The Universal Gunbearer will fit any pack but you can shave some weight, or excess strapping, by going the non-universal route. I have owned several different Kifaru bags from Highcamp to EMR II but I think the DT1 is probably the sweet spot between simplicity and organization. I like the EMR II, but it is almost too much organization. The Highcamp is almost too little organization. They are all great bags. I have found that my preferences have changed over time. The DT1 is a great choice.
