I've got a couple of the "3 day assault packs". One in digital green, the other in desert camo, picked up cheap at gunshows. $25-$30 IIRC. They are great day packs for the money. Mine were lightly used, and I've seen a few new for around $90. Just be careful it is military issue. Lots of cheap knockoff's
I don't use mine for a range bag. I found a cloth tool bag from Home Depot to work better than any of the range bags I've seen and they are a lot cheaper.

Plus, it doesn't scream "guns inside" in my vehicle.
