⚠ Regulator not included. Compatible with all standard 5/8-18 UNF HPA regulators — see our HPA Regulators collection. The HK Army HP8 works great with this tank. Tanks are supplied empty.

The most compact carbon fibre tank in the HK Army Alpha range, the 48ci is the choice for players who want lightweight HPA in a short package — CQB builds, speedsoft rigs, or any setup where a longer tank would get in the way. At 4500psi it holds significantly more air than a 3000psi aluminium bottle of the same size, giving you more shots per fill without adding bulk.

Carbon fibre wrap over an aluminium core means it’s considerably lighter than a comparable aluminium tank. The Alpha range is HK Army’s lightest carbon tank series, built to meet DOT/TC-UN (ISO11119-2) safety regulations and independently inspected. Available in Shadow and Doom Midas colour finishes.

Frequently asked questions

Is a regulator included? No — add an HPA regulator separately to match your engine.

Why choose 48ci over 68ci? The 48ci is lighter and more compact, ideal for CQB and speedsoft where weight and low profile matter most.

What thread does it use? Standard 5/8-18 UNF — fits standard airsoft HPA regulators.

🔧 Titan Forge Airsoft tip: The 48ci is the ideal tank for a pistol HPA adapter build or a speedsoft setup where a longer tank would be a liability. If you’re running a standard field rifle and want fewer refill trips, step up to the Alpha 68ci — the sweet spot for most players.
