***OG KILLA MODIFIED***- Joe Sanchez of the East Side Menkar modified his 1500 by drilling a hole in the water container and running a hose from a two liter bottle strapped to the top, into the tank. He used epoxy to seal it up and it doubles the 1500's water capacity. He rigged it through the bottom ridges of the 2L bottle so if you need a quick load, you can loosen the 2L cap and gravity fills the 1500 tank. From what I can tell (I haven't shot it) the OGKM is still really sturdy and the weight isn't very bad, the 2L can be balanced easily.
