Well here I am late to the party. I have one called the Fieldline Pro Series. I think I bought it at Wally World for about $15. I don't have any pics but it has a 12" by 6" center compartment, a small zippered one in front where I carry my tape and staple gun with staples for targets. It has two wide mouth compartments, one on each side they can hold several mags each, and a small open compartment on the back where I keep my selection of range tools, like my screwdrivers, leatherman tool etc. I like the shoulder strap that keeps my hands empty for pistol or rifle cases and such. My wife got it for me for my birthday a few years ago.
I ordered a bulldog case for my mossberg shotgun from opticplanet...haven't gotten it yet.
I also have a plano ammo box enroute which seems like a 50 cal size . I will bring that to the range to bring ammo, ear and eye protection, staple gun , and targets.
Optics planet has a terrible reputation for taking your money and then ordering the item that you ordered and have it drop shipped to you from someone else.
