One of mine is an Eagle rig, it holds eight rifle mags, four double stack mags and there is molle on both sides of the mag wells. It also has an open type back,(no plate carrier) it makes it really cool in the heat. It's been a good rig. It's been a long time since I bought it, or I'd tell you the name of it, I don't remember.
I like the tactical tailor two piece mav. With the X harness its pretty comfortable and opening from the front its easy to get on and off. Its pretty adjustable so I dont think you would have any trouble fitting it to your frame.
