HK Army Alpha Air 68ci 4500psi Carbon Fiber Tank (Bottle Only)

The HK Army Alpha Air 68ci is built using the lightest carbon fiber construction HK Army has released to date. Wrapped in carbon fiber and rated to a full 4500psi fill, this bottle cuts weight off your marker without giving up any of the 68 cubic inches of air paintball players rely on for a full day on the field. Built for players who feel every ounce hanging off their marker, the Alpha Air 68ci pairs a compact 4.4in diameter with an 8.2in length and a bottle weight of just 1lb 8.6oz (0.7kg) — noticeably lighter than most 68ci carbon fiber tanks on the market. It's available in a wide range of color finishes, so you can match your tank to your marker and loadout.

If you need a regulator, any HK Army regulator will fit — Standard, MP5, HP8, and Turbine Pro — along with regulators from Ninja, Immortal Air, and Empire, or use our Tank Builder to select a bottle and regulator together as one complete system. What does 4500psi mean for this tank? 4500psi is the tank's rated fill pressure — the maximum pressure the carbon fiber bottle is built and certified to hold. A fill station set to a 4500psi fill will bring this tank to its full 68ci capacity. Will any regulator fit the Alpha Air 68ci? The Alpha Air 68ci uses a standard tank valve thread shared across most paintball regulators, so any HK Army regulator will thread on — Standard, MP5, HP8, and Turbine Pro — along with regulators from Ninja, Immortal Air, and Empire. If you're unsure about a specific regulator, use our Tank Builder to pick a matched bottle-and-regulator combo. How is the 68ci different from HK Army's other Alpha Air sizes? HK Army offers the Alpha Air in five capacities: 48ci, 68ci, 77ci, 88ci, and 98ci. Larger capacities hold more air and more shots per fill but are bigger and heavier; the 68ci is a popular middle-ground size that balances air volume with a manageable size and weight on the marker. Is the Alpha Air really the lightest carbon fiber tank HK Army makes? Yes. HK Army built the Alpha Air line specifically to be its lightest carbon fiber wrapped bottles to date, cutting weight versus its other carbon fiber tanks without reducing air capacity. How often does a carbon fiber air tank need to be retested? Composite (carbon fiber) paintball tanks are DOT/TC certified and, like other composite tanks, generally require a hydrostatic retest every five years from the date of manufacture to stay in service. Check the date stamp on your bottle for its exact retest date.
