Both hose options are discontinued by the manufacturer and is no longer available. Sorry! October 2009. Part # 164483-000 has been discontinued. If you choose to order this item you will receive a longer hose which will require you to remove your foregrip, and connect the braided hose from the bottom line adapter straight to the gun. There are 2 versions of the Triad. One came with a foregrip and uses this short Braided hose (164483-000). The other did not have the foregrip and therefore uses the longer braided hose (131588-000).
