no pics yet but I do have some more stuff to comment on.
Whoever designed this PC needs to be punched in the face for being an idiot and putting a 2" fastex buckle right where you'd shoulder your rifle. Perhaps they were thinking it would be easier to remove the PC if you needed medical aid, but the same thing could be achieved by undoing the side buckles and flipping the PC over the head of the casualty. By reversing the PC it does alleviate this problem, but opens up another one. Securing the side buckles is a PITA now, I can do it myself but if you're not flexible it's not going to be easy. To be honest though, with the cummerbund I dont' think that those straps really do a whole hell of a lot.
For height adjustment the 2" strap has velcro sewn onto it so you can secure it to itself. Not a bad idea...except for me there's not enough hook to really get a good bite on itself IMHO. I want to see if I can get it a little higher since I think it's sitting a bit low at the moment. I have some of it on itself, but not enough to really be to my liking. That said I can jump around and do the mil-spec monkey dance and it doesn't come loose with 4 loaded AR mags, 2 loaded pistol mags, and 2 ceramic rifle plates.
As for the plates, they drop right into the plate pocket so there isn't any adjustment in that sense. I have standard sized trapazoidal cut plates, and they fit perfectly. Rectangular plates should fit in there as well. The one nice thing is that the plates drop in from the top, so unless you're going to be doing some tactical ninja cartwheels they're not going to come out unless you want them out. The pockets secure shut at the top with velcro right between the shoulder straps.
I did remove the cummerbund from mine to see how it would feel without it. I'll be honest, it helps a lot to keep the PC tight to your body. Without it, there's a bit more side to side movement as one would expect.
