Picked this up a few weeks ago, and I'm very happy with it. Quality is excellent, and all hardware looks/feels top notch. The picture shows the MOLLE webbing as an OD solid color, but mine was full multicam.
Rig is very adjustable, I'm 5'9, about 140lbs, and I was able to adjust it to fit very securely. I run it with the rear straps in an x pattern to make even more secure.
Was able to fit 3 open-top M4 mag pouches and a universal holster on it.
Mine also came with a buuuuunch of strap retention elastic bands, which was great.
Quality is excellent.
Hardware is excellent.
Can mount a hydration pack or plate panel on the back.
None that I can think of, except maybe price, but you get what you pay for.
