So the tank on the Alpha/Delta Wolf are removable and have a valve so they don't empty. Any word on there being valves available to carry an extra tank?
So this does raise a question of compatibility:
From website:
This spare bottle from Omega Air allows you to carry a spare lightweight bottle, giving you an extra 480cc of volume on the go.
480cc capacity 4500 psi fill pressure Valve fits LCS and FX bottle rifles (Excludes Impact M3)
Does this mean there is some compatibility between brands and valves? I'll try and give AoA a call tomorrow for more details.
