A complete HPA setup has six things in it: a rifle built for HPA, an air tank, a regulator to step the tank pressure down to working pressure, a line connecting the regulator to the rifle, the engine inside the rifle, and the BBs. Get any one of these wrong and the rest of the system suffers — under-spec the regulator and you'll starve the engine; over-spec the tank and you've added unnecessary weight; pick the wrong line length and the rifle won't sit right on your rig.
This collection is everything across that stack: rifles, tanks, regulators, lines, engines, pistol adaptors, and MTW spares. We're the UK supplier and repair centre for Wolverine Airsoft, an authorised dealer for Heretic Labs, GATE, HK Army, PolarStar, and Amped, and we run every system we stock.
If this is your first HPA setup, start with the HPA Airsoft UK guide — it covers tank sizing, regulator selection, line lengths, and the trade-offs between platforms. If you already run AEG and want to convert, the AEG to HPA conversion guide walks through it. And if any of the kit you order needs installing, tuning, or servicing, the HPA tech service handles that — on-site at Skirmish Wycombe or by post.
