The HK Army 15ci 4500 PSI Aluminum Tank pushes aluminum air systems into a new category. Built for players who want a compact setup without sacrificing pressure capacity, this tank delivers extended air volume in a durable, streamlined package. It’s a serious upgrade over traditional 3000 PSI aluminum tanks, giving you more shots and more consistency in a smaller footprint.

Designed as a reliable alternative to bulkier carbon fiber systems, this tank is ideal for HPA users running lightweight builds, tapped pistols, or compact rifles. Paired with a standard high-pressure regulator outputting 800 PSI, it ensures consistent performance shot after shot.

Compact, durable, and efficient, this is the next evolution of aluminum air tanks.
