HK Army 13ci/3000psi Compressed Air HPA Paintball Tank Air System w/Regulator – Black

The HK Army 13ci/3000psi tank is designed for specialty formats where size and maneuverability are critical. This tank is the smallest and lightest aluminum HPA system available, making it ideal for pump, pistol, or magfed markers where a large bottle would interfere with the profile.

Best for: Magfed players, pump gun enthusiasts, small-profile markers, and youth/low-impact leagues.

Expert Opinion: The 13ci tank solves a specific problem: providing stable HPA in the smallest footprint possible.

Comparison Insights: Finding Your Best Paintball Air Tank

Choosing the right HPA tank system primarily comes down to capacity, weight, and budget. While every tank listed here is a reliable option, they cater to different player needs.

For players focused on maximum affordability and durability, the 48ci/3000psi aluminum tanks (like the HK Army and Maddog versions) are the clear winners. They offer robust performance and consistency for a much lower entry cost.

If your priority is high performance and reduced weight, you must look at the HK Army 68/4500 Aerolite Carbon Fiber. These tanks hold 50% more pressure and are significantly lighter, making them essential for competitive play where fatigue and shot count matter most. This lightness comes at a premium price, but the performance payoff is worth it.

When considering longevity and maintenance, note the unique benefit of the HK Army 13ci/3000psi. This small tank’s hydro re-test exemption means its operating life is dramatically simplified, requiring zero mandatory testing after the initial purchase date, unlike the larger 48ci and 68ci tanks which require re-testing every five years.

Finally, always confirm the Date Stamped on the Tank. This date is the manufacturer date, not an expiration date. Your tank is typically safe and certified for five years from that date before the hydro re-test is required.

Final Verdict: Which Air Tank Should You Buy?

Deciding on the best paintball air tank isn’t about finding a single “best” product, but finding the best fit for your style of play and budget.

The Entry-Level Champion: If you are a casual player, a beginner, or simply looking for the most bang for your buck, you cannot go wrong with the HK Army 48ci/3000psi Aluminum Tank. It delivers stable HPA performance affordably and reliably.

The Performance King: For the dedicated tournament player, or anyone who hates carrying heavy gear, the HK Army 68/4500 Aerolite Carbon Fiber Tank is the essential upgrade. The weight savings combined with the massive shot capacity make it worth the investment.

The Specialist’s Pick: If you run a compact setup—such as a pump marker, a pistol, or a magfed marker where space is tight—the HK Army 13ci/3000psi Tank is the perfect choice. Its hydro exemption is an added bonus that simplifies ownership.

Frequently Asked Questions About Best Paintball Air Tank

What is the difference between 3000psi and 4500psi tanks?

The primary difference is the maximum amount of air pressure (and thus, shot capacity) the tank can safely hold. A 4500psi tank holds significantly more air than a 3000psi tank of the same volume (e.g., a 68ci/4500psi tank offers roughly 50% more shots than a 68ci/3000psi tank). 4500psi tanks are almost exclusively made of carbon fiber to handle the higher internal pressure, making them lighter but more expensive.

Why do some paintball air tanks need to be Hydro Tested?

HPA (High-Pressure Air) tanks must be regularly hydro tested (hydrostatic testing) to ensure the integrity of the cylinder walls hasn’t degraded under continuous high-pressure use. The Department of Transportation (DOT) requires tanks larger than 2 inches in diameter and over 24 inches in length to be tested every five years from the date of manufacture. Tanks that are exempt (like the small 13ci cylinders) do not require this periodic testing.

Should I choose HPA or CO2 for my marker?

While CO2 is cheaper and easier to obtain, HPA (High-Pressure Air) systems offer vastly superior performance. HPA maintains a consistent pressure output regardless of ambient temperature, leading to greater velocity stability and enhanced accuracy. CO2 output fluctuates with temperature, causing inconsistency. Almost all modern and competitive markers require HPA to function correctly.

What is the standard output pressure for these tanks?

Most paintball regulators on the best paintball air tank systems (including all those reviewed here) are set to an industry-standard output pressure of 800 psi (or 850 psi). This is the safe and optimal pressure required to run most mechanical and electronic paintball markers effectively. Markers with low-pressure operation will typically have a secondary regulator built into the gun to further drop this pressure down.

How many shots can I expect from a 48/3000 tank versus a 68/4500 tank?

Shot capacity depends heavily on your marker’s efficiency, but generally:
* 48ci/3000psi: Approximately 400 to 600 shots.
* 68ci/4500psi: Approximately 1,000 to 1,300 shots.

This vast difference is why serious woodsball or speedball players rely on the higher capacity of carbon fiber tanks.

Can I fill my own HPA tank at home?

Generally, no. HPA tanks must be filled using specialized, certified compressors capable of reaching 3000 psi or 4500 psi, depending on your tank’s rating. Attempting to fill an HPA tank with a standard home air compressor is impossible and unsafe. You must visit a paintball field, specialized dive shop, or a dedicated air filling station.
