HK Army Alpha Air 77ci 4500psi Turbine Pro Air System
The HK Army Alpha Air 77ci 4500psi Turbine Pro Air System gives you more air than a 68 without jumping to a long, heavy bottle, paired with HK Army's flagship regulator, the Turbine Pro. It comes assembled with the standard body Turbine Pro in black, so you just get it filled and you're ready to go.
The 77ci comes in 16 colors: Abyss, Blizzard, Graphite, Haze, Ignite, Shadow, Striker, Summit, Surge, Toxic, Viper and Void, plus four DOOM editions: Alloy, Ghost, Midas and Scorch. Colors come and go as we restock, so the ones you can pick above are ready to ship.
Turbine Pro: Adjustable Output From 350 to 650 PSI
This is the big reason to step up from the HP8. The Turbine Pro ships set at 450 psi, which suits most high end setups. If yours wants something different, the included laser etched shims let you switch between 350, 450, 550 and 650 psi. A brass air flow stabilizer smooths out the first rush of air for steadier pressure every time.
Put the Gauge Where You Want It
The 360° rotating cap lets you turn the gauge and fill valve to whatever spot works for you, then lock it down with set screws. The burst discs sit low and close to the body, and the spring loaded fill valve plus rubber cover help keep dirt out.
Alpha Air 77ci: The Sweet Spot Between Air and Size
You get 9 extra cubic inches over a 68ci for more air per fill, but the bottle is still only 9" long and weighs 1 lb 12 oz. It's a great choice for long days at the field or if you just hate walking back to the fill station.
Built and Certified for Safety
Every Alpha Air bottle is made to DOT/TC-UN (ISO 11119-2) standards and inspected by an independent agency. It's certified for use in the USA, Canada and Europe and has a 5 year hydro. Every Turbine Pro is leak and pressure tested before it leaves the factory.
