The HK Army Alpha Air Tank Builder lets you put together your own complete air system, one order at a time. Choose a carbon fiber bottle size and the regulator that matches your setup, and we ship it to you as one matched, ready-to-fill system - no guessing whether parts picked separately will actually work together.
Every bottle in the HK Army Alpha Air line uses the same lightweight carbon fiber construction and 4500psi rating, whichever size you choose, and it's available in a wide range of color finishes. Pick your capacity, pick your regulator, and you are set.

Frequently Asked Questions
Pick your Alpha Air bottle size - 48ci, 68ci, 77ci, 88ci, or 98ci - and your regulator - Standard, HP8, MP5, or Turbine Pro - and we'll put them together and ship you one complete, ready-to-fill air system.
Standard runs a fixed 800psi output. HP8 runs a 700-800psi output. MP5 runs a fixed 450-550psi output. Turbine Pro is rotational and adjustable across a 350-650psi range for players who want to fine-tune their output rather than run a fixed setting.
It comes down to how much air you want between fills versus how much size and weight you want to carry. The 48ci is the smallest and lightest bottle in the lineup, the 68ci and 77ci step up in capacity while staying compact, and the 88ci and 98ci increase length and weight for the benefit of more air.
Yes. Each Alpha Air size is also available as a bottle-only listing if you already have a compatible regulator, and any HK Army regulator will fit, along with regulators from Ninja, Immortal Air, and Empire.
Yes. Every Alpha Air bottle uses a standard tank valve thread, and each regulator option uses the same standard fitting found on most paintball and airsoft equipment, so this system fits virtually any setup that runs on compressed air.
No. Like all paintball air systems, this ships empty. You'll need to fill it at a certified air station or field once it arrives, up to its rated 4500psi capacity.
