I have the Blackhawk drag bag, though it's not the one with the shooting mat. I didn't like the idea of have to unroll the mat every time I wanted to get the rifle put of the case. The drag bag has held up very well over the last 18 months or so, although I haven't been crawling through the jungle with it, just to and from the range. The bag holds a lot of stuff. I can generally fit everything I need for a range trip in it, including spotting scope, cleaning gear, ammo, binos, etc. I especially like the full length cleaning rod pocket (although I added a steel cleaning rod case, to prevent the rod from flexing in the bag). I also added a shoulder strap, which I use more often than the backpack-style straps. Overall, a good rugged piece of gear.
Oh, and it came in a plain cardboard box.
