The HK Army Alpha Air 77ci 4500psi HP8 Air System gives you more air than a 68 without making the jump to a long, heavy bottle. It comes as a complete system with the HP8 regulator installed, so you can get it filled and get on the field.

The 77ci comes in 16 colors: Abyss, Blizzard, Graphite, Haze, Ignite, Shadow, Striker, Summit, Surge, Toxic, Viper and Void, plus four DOOM skull editions: Alloy, Ghost, Midas and Scorch. Colors come and go as we restock, so the ones you can pick above are ready to ship.

Alpha Air 77ci: The Sweet Spot Between Air and Size

A lot of players end up on a 77 because it's the best of both worlds. 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 if you play long rec days, go through a lot of air, or just hate walking back to the fill station.

Lighter Carbon Fiber Than You'd Expect

Alpha Air is HK Army's lightest carbon fiber line. The bottle keeps the same 4.4" diameter across every size, so the 77 tucks in right where your 68 did and just runs a little longer. Your setup stays balanced, and you're not carrying extra weight.

HP8 Regulator With 800 PSI Output

The HP8 is HK Army's standard output regulator at 800 psi, and it works with most paintball and HPA airsoft setups. A built in gauge shows your remaining air at a glance. Need a spare or replacement? The HK Army HP8 regulator is also sold separately.

Custom Setups and Bottle Only

Want a different regulator, like the Turbine Pro? Build exactly what you want with our Alpha Air Tank Builder. If you already own a regulator, the Alpha Air 77ci bottle is available on its own.
