Shop HK Army Compressed Air Tanks
HK Army builds some of the most trusted compressed air systems in paintball, and Discount Paintball carries the full lineup — from ultra-light carbon fiber bottles to affordable aluminum tanks for beginners and backup setups. Every tank here is DOT & TC approved and backed by a 5-year hydro testing cycle.
AeroLite vs. HSTL Carbon Fiber Tanks
The AeroLite line is built around ultra-lightweight carbon fiber construction paired with a reliable aluminum regulator — a great fit for players who want to shave weight off their setup without sacrificing air efficiency. The HSTL system carries HK Army's signature colorways while delivering the same dependable 4500 PSI performance. Both are sold bottle-only for players upgrading an existing regulator, or as a complete bottle-and-regulator system through our Tank Builder.
48ci/3000psi Aluminum Tank
Looking for a reliable, budget-friendly option? The HK Army 48ci/3000psi aluminum tank ships as a complete system with the regulator already installed and set to a standard 800 PSI output. It's a popular choice for new players, rental fleets, and anyone who wants a dependable backup tank without the cost of carbon fiber.

HK Army Air Tank FAQs
Carbon fiber tanks (AeroLite, HSTL) are lighter weight and run at 4500 PSI for more shots per fill in a smaller, lighter bottle. The aluminum 48/3000 tank is heavier but more affordable, and ships as a complete system with the regulator already installed — a great choice for beginners, backups, or rental use.
Both are 4500 PSI carbon fiber systems with comparable performance. AeroLite is built around minimal weight, while HSTL is built around HK Army's signature colorways. The choice usually comes down to look and feel.
The AeroLite and HSTL bottle-only listings do not include a regulator — they're designed for players upgrading an existing reg. If you need a complete system, use the Tank Builder to add a regulator of your choice, or shop the 48ci/3000psi aluminum tank, which comes with one installed.
