Frequently Asked Questions
The HSTL Tank Builder offers three HK Army regulator options. The Standard Regulator is the most affordable option and a reliable choice for recreational and competitive players. The HP8 Regulator is a step up, available in multiple colors — great for players who want to match their setup. The MP5 Regulator rounds out the lineup as a performance-focused option for markers requiring lower pressure. All three regulators are compatible with the HSTL 68ci carbon fiber bottle.
The HSTL carbon fiber bottle is available in 68ci only, weighing in at just 2lbs 2oz with the Standard Regulator attached — built for players who want a lightweight setup without sacrificing air capacity. If you're looking for a 48ci option as well, check out our HK Army AeroLite Air Tank Builder, which offers both 48ci and 68ci bottles.
The HSTL carbon fiber bottle is available in Black White, Blue White, Gold Black, Purple White, and Red Black. The HP8 regulator is also available in multiple colors, so you can mix and match your bottle and regulator to create a custom look. The Standard and MP5 regulators are available in Black.
Yes. All HK Army HSTL regulators use a standard thread pattern that is compatible with virtually all paintball markers and airsoft guns that accept a compressed air HPA tank. If you're unsure whether your specific marker is compatible, feel free to contact us before ordering.
Yes — just let us know above. We can assemble your HSTL tank and have it ready to fill and play right out of the box. If you prefer to put it together yourself, we can ship it unassembled as well.
The HSTL bottle operates on a five-year hydro cycle. The tank must be hydrostatically tested and recertified every five years from its manufacture date to remain legal for use and refilling. Most paintball pro shops and dive shops offer hydro testing services.
No problem. Just choose "None" above for the regulator or bottle. OR, if you already have a regulator and just need a replacement bottle, you can purchase the HSTL 68ci Bottle Only separately. Regulators are also available individually in our HK Army Regulators collection.
