As a soldier, avid outdoorsman and firearms instructor, I have encountered many packs and range bags.  My initial impressions of this one are that it is a very good idea and a remarkable bargain for such quality at under $70.  Upon receiving it, I expended an entire aerosol can of waterproofing on its inside and outside.  It is tightly and strongly made, and there are many nooks and crannies.  The product video will help some purchasers assemble it.  True, it is not an ideal backpack, but it can certainly be carried short distances.  More importantly, it is a great disguise.  I live in a high rise situated in a university town where backpacks are ubiquitous and firearms are not universally loved. I wish I had ordered the green one. Even in brown, it attracts no attention in elevators, hallways, parking lots, etc.  It needs, as other reviewers mention, external Molle attachment strips, and all of the velcro should to be about twice as wide.  The initial design appears to originate with competitive shooters - thus the many magazine loops, stapler pouch, etc., that are useful for those who want to score points in shooting games.  Of the five external pockets, three are the same small size, just right for competitors' magazines, but impractical for much else. Two of these could usefully  be replaced with a single, general-purpose pocket.  Happily, more serious shooters with practical goals will find that the pack's fundamental design allows much customization.  To accommodate the procedures of an indoor range where I often teach, I have added an external earmuff container and a tube to contain rolled targets of the appropriate size.  If the pack holds up under hard use, I'll probably buy another in green and set it up for outdoor ranges.  By then, this company or a competitor may offer a similar pack with more adaptable features..  As it is, even with a few shortcomings, this is a solid piece of gear at a very favorable price.
