carbon Fiber bottle

I got a 500 cc / 0.5 L bottle from Ali ( can not remember the brand ) but it look & feel as good as any other bottle i have seen, picked up a stainless FX bottle insert in the UK.

Now all my CF bottles work on both my Maverick and AGT Vulcan 3, and i can swap tanks without loosing plenum pressure, which are a big deal not least in the Vulcan 3 with its huge plenum, and not least since i only use the small plenum as a .177 shooter.
So the Vulcan 3 in small plenum setup have like 100 - 150 CC of volume in front of the regulator, and then + what ever is in the tank.

Mind you the original AGT bottle, the not valved fitting in it,,,, all i have left now to get it out is to heat it to temperatures way past my comfort zone, CUZ damn that thing are in there good,,,,, but i refuse to believe it is part of the ALU the CF are spun around, so it just got to be able to come off, but GD AGT have gotten that part mounted strong.
