I got this pack when I got my A5 from Ozark Sports World.
It's cheap, simple, better than nothing.
Bad: 1. It doesn't come with suspender straps, so you have to buy them seperate. If you don't get them, the pack will feel very heavy when fully loaded, and will either drag your pants down or the buckle will come loose and the pack will fall (awkward when your gun is attached with remote!). 2. Since the pods are horizontal they protrude further out than your body, making you a wider target. I've gotten shot on the side of the pack several times. 3. It doesn't have any additional pockets to put allen wrenches in or anything.
I'd recommend getting some sort of vest instead. This product puts alot of weight on your hips and makes you less manueverable.
