I just tried to snap some pics and they all look terrible. I just have my cell phone and it's not easy to get a good shot of front compartment.
BadBoyBeesons photos are better than anything I can create.
I have a couple of Maxpedition Velcro mag carriers in there. They are holding a flashlight, multitool, a small first aid kit, and a few other small items.
You could fit 4 AR mags in there (horizontally) with the right Velcro pouch.
And anything you put in there is accessible with either hand.
