HK Army Alpha Air® 15ci Carbon Fiber Tank – Ultra-Lightweight Bottle Only

The HK Army Alpha Air® 15ci is the smallest and lightest carbon fiber air bottle in the Alpha Air lineup, purpose-built for compact marker setups, air-through-stock systems, and minimalist loadouts.

Engineered to be the lightest carbon fiber wrapped bottles ever released by HK Army, the Alpha Air series redefines what’s possible in weight reduction without compromising strength or performance. The 15ci size is ideal for magfed players, CQB builds, less-lethal platforms, and markers where balance and compactness are critical.

With a 1.95-inch diameter, the Alpha Air 15ci fits seamlessly into air stocks and tight configurations where traditional tanks are not an option. At just 8 oz (0.22 kg) for the bottle alone, it dramatically reduces rear-end weight, improving handling, maneuverability, and overall fatigue during extended use.

This listing is for the bottle only. A regulator is not included, allowing you to select the output pressure and regulator brand best suited to your marker and application.
