I will post some pics of my recon tonight, to show how I have the hydro setup.
Theres also a Recon set like mine on MM, but I didnt like the way the Hydro was atached.
I also have my Recon set so when I am laying prone. The buky part of the recon is right under my chest acting like a pillow(well kinda hard pillow)proping me up 6-8 inches. I have no problems with low craws or sliding down a moutain(yes I have done it) on my rig. I did have to relocate my side arm to my drop leg,
