    the ball at the end is the cocking mechanism that strikes the release valve for the air. so not really, with this design

    I see your point. but the bottle on the front has a smaller diameter then the rear, its fairly "skinny", this way, the barrel guard will still mount to the bipd.

    Wanted to add more bottle volume to my Panthera but didn't like the look of the Panthera without the barrel guard. Saw Saber Tactical's Drop-down front bottle adapter and gave it a try. https://sabertacticalinc.com/products/fx-panthera-drop-down-adapter-st00xx. stainless steel...

    I saw that one. but I hate the idea of the fill probe, I get confused on which gun which fill probe. the dual pressure gauge is helpful in the older version
