15ci / 4500psi Aluminum Compressed Air Tank - Black | HK Army

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. These do NOT fit the Wolverine Tank stocks sadly. We have not tried other tank stocks. Please check the diameter of yours to confirm.
