Currently, I have my Scorpion in a nice little backpack. Unassuming because it doesn't scream tactical but I just recently finished modding my AR pistol and want that around as a backpack truck gun. It's 10.5 in barrel with a Law folder + brace, so it folds nicely to a length about 23 inches. So anybody have ideas for a relatively good priced backpack that can fit something like that?
