Our traditional style bottomline (not the on/off), coupled with our most popular Drop Forward, the Drop #1. Now packaged together with the grip frame mounting screws and 2 - 1/8" N.P.T Pipe Plugs. The bottomline is tapped for three gas exit holes so you can find the hose configuration most comfortable for your shooting position. Then plug the other two holes or screw in a guage if you like. The Drop #1 pulls the bottomline up nice and tight to allow your tank to get into your bunker with you! Light, tight and cheap: What a deal! Hook yourself up anytime you like!
