I really love the look of these tanks. COV didn't have the full metal ripple one in stock, so I ordered one with the plastic tube and then just the metal ripple tube separate. It looks awesome on my all chrome bolt mod, but for the life of me I can't seem to refill it without juice practically pouring out through the bottom o-rings. I've tried taking the top cap off, just pulling the cart down and I also switched out the o-rings to the larger ones that COV offers for free. I'm still using it but it's becoming a special occasion tank unless I can fix the leaking issues. But she is a looker!
