HK Army Alpha Air Bottle 77ci – Ultra-Lightweight Carbon Fiber Tank (Bottle Only)

The HK Army Alpha Air Bottle 77ci represents the next evolution in lightweight carbon fiber air systems. Engineered to be the lightest carbon fiber bottles ever released by HK Army, the Alpha series pushes the limits of weight reduction without sacrificing capacity, strength, or performance.

Designed for competitive paintball, magfed play, and scenario environments where balance and endurance matter, the Alpha 77 delivers a high-capacity air solution in a remarkably compact and lightweight profile. By reducing overall system weight at the rear of the marker, this bottle helps improve handling, stability, and player fatigue over long days on the field.

The Alpha 77 features a slim 4.4-inch (112mm) diameter, making it comfortable for shouldering and compatible with a wide range of tank grips, stocks, and marker setups. At just 1 lb 12 oz (0.9 kg) for the bottle alone, it significantly undercuts traditional carbon fiber bottles of similar size.

This listing is for the bottle only. A regulator is not included, allowing you to pair it with your preferred output pressure and regulator brand to build a system tailored to your marker and playstyle.
