10 Best Paintball Tanks 2025 in the United States

The Maddog 20 oz CO2 Paintball Tanks come in a useful 5-pack with empty, refillable aluminum cylinders designed for paintball and airsoft. Their 20-ounce size is a common standard for CO2 tanks, providing enough gas for approximately 800 to 1000 shots per fill, which is great for players who want to avoid running out of air during games. Made from durable, lightweight aluminum, these tanks are built to withstand the physical demands of paintball without adding unnecessary weight to your gear.

These tanks feature an industry-standard brass pin valve and are DOT and TC certified, meeting safety standards with a 5-year hydro testing cycle. This means they must be re-tested every five years to ensure safe use, which is typical and important for CO2 tanks. The tanks ship empty for safe transport and must be filled at a proper refill station, like a paintball field or sporting goods store. Since they use CO2, pressure can fluctuate with temperature changes, which is common for this type of tank but may affect consistent shot performance compared to compressed air tanks.

These Maddog tanks are a solid choice if you need multiple reliable, lightweight CO2 tanks for frequent play or team use. They fit all standard CO2-powered paintball markers and offer good value in a multi-pack. However, if you are looking for tanks with built-in regulators or prefer compressed air systems, you might want to consider other options.

The HK Army Aerolite HPA Air System is a lightweight, high-performance carbon fiber tank designed for paintball and airsoft players who value reliability and ease of use. Its 48 cubic inch size combined with a 4500 psi pressure rating offers a good balance of air capacity and compactness, making it suitable for players who want to stay agile without sacrificing too much airtime. The tank’s carbon fiber material keeps it very light at just over 2 pounds, which helps reduce fatigue during long gameplay sessions.

The included aluminum regulator is solid and provides a consistent output pressure of around 850 psi, which is ideal for maintaining steady shots and improving accuracy. Safety is well-addressed with adherence to DOT/TC-UN standards and built-in burst disks, giving extra peace of mind when handling compressed air. The tank supports a 5-year hydro testing cycle and has a 15-year lifespan, which means it’s built to last with proper maintenance.

The relatively small 48ci size means it won’t hold as much air as larger tanks, so players who play longer or prefer fewer refills might look for bigger options. Also, the 90-day limited warranty is a bit short compared to some competitors. This tank is a great fit for players looking for a durable, lightweight, and reliable air source for standard paintball or airsoft play, especially if portability and consistent output are priorities.

The Action Village Empire Axe 2.0 package is designed for paintball players seeking a reliable and competitive marker with a quality air tank included. It features a 68 cubic inch carbon fiber air tank rated at 4500 psi, which is lightweight and DOT & TC certified for safe use in the US and Canada. The aluminum regulator is rebuildable, includes dual burst disks for added safety, and outputs a consistent 800 psi without pressure adjustment options. The tank requires hydrostatic testing every five years over its 15-year life, typical of high-pressure paintball tanks.

The Empire Axe 2.0 marker uses a pressure-controlled inline poppet engine that delivers smooth and accurate shooting, with multiple firing modes accessible via the Shockwave board. Maintenance is simplified thanks to a tool-less bolt removal feature. The aluminum barrel balances weight and durability. Included is a Halo Too loader, known for quiet operation and strong anti-jam performance, which is battery-powered and requires 4 AA batteries that are not included. Flexible swabs are also bundled to help keep the barrel clean during play.

While the tank pressure isn’t adjustable and the loader requires separate batteries, this package suits entry-level to intermediate players who want a solid setup without complex customization. Its combination of lightweight materials, safety features, and versatile firing modes makes it a practical choice for casual or competitive paintball.
