The 15ci/0.23L size at 4500psi is the sweet spot for compact HPA builds: substantially more air capacity than a 13ci/3000psi tank in barely more physical volume, thanks to the higher fill pressure. That translates to a noticeably higher shot count per fill while still fitting stock-internal mounts and compact back-rigs.
The higher 4500psi rating is the key difference from common 3000psi tanks. More stored air at higher pressure means more shots between fills — practically, the difference between needing a mid-game top-up and running a full skirmish on a single fill. The regulator steps the pressure down to your engine's working range as normal.
Construction is a carbon-fibre-wrapped bottle, keeping weight low despite the high pressure rating. The UN certification means the bottle meets international transport and pressure-vessel standards — relevant for refilling confidence at dive shops and paintball sites, which increasingly ask for certified bottles before they'll fill.
Supplied with the POWAIR regulator on the Tactical Line RS specification. Standard paintball-thread output, compatible with the usual HPA line fittings. A strong choice for players upgrading from a low-capacity 13ci tank who want more shots without moving to a bulky back-mounted bottle.
