HPA Magazine Adapters

HPA Magazine Adapters UK

An HPA magazine adapter lets a gas blowback pistol run on air from a line instead of gas held in its magazine. It connects to an air line from a regulator and, apart from the Balystik connector, feeds BBs from a separate magazine. Most are made for one pistol's magazine pattern, and most fit onto a gas magazine you already own, so the chart below lists them by pistol: TM Hi-Capa, AAP-01, TM Glock, and the Novritsch SSP5 and SSP1, with the gas magazine each one needs.

Most HPA adapter ordering mistakes come down to the donor magazine, so check which gas magazine each adapter fits onto in the Donor gas magazine column of the chart below before you order.

They come in a few types. M4 adapters take an AEG M4 magazine. Angled adapters hold the M4 magazine at an angle rather than straight down, and AirTac's modular angled adapters, including the 2026 Edition, run it parallel to your wrist for a smaller vertical profile. MP5 adapters for the Hi-Capa, Glock and AAP-01 take CYMA mid-cap MP5 magazines. The AirTac / T1P shotgun shell adapters feed from 30 round shotgun shells. CTM's M4XIMUS kits take M4 magazines and have a side window that shows the BBs, and CTM's MP5 adapter lets a fitted M4XIMUS kit take MP5 magazines. The Balystik connector is a direct line fitting: it swaps the fill valve of a WE or KJ Works gas magazine for a US Foster nipple, so the magazine runs from the line.

AirTac UK's adapters for the Hi-Capa, Glock and AAP-01 are also grouped together under AirTac HPA adapters.

For the line between regulator and adapter, see HPA lines. The same adapters are grouped by platform under AAP-01 HPA adapters and Hi-Capa HPA adapters, and a tank, regulator and line come together in the HPA bundles.
