Our Universal Warp Feed adapter makes installation a breeze. If you are upgrading from the AGD kit you will want to add it for most markers. Fits standard 7/8" O.D. feed tubes and 1.050" I.D. feed necks (original WGP I.D. size - please check before ordering), and includes the special AGD Parabolic Feed Plug. We also offer a "Stove Pipe" Adapter that screws on to any removable vertical feed port using the Autococker thread (MicroMag, VL Maxis, etc.) that really lowers the profile as well.
