This HPA adapter represents the culmination of months of work to produce, from scratch, a shortened magazine for the GBB MAC11. This leads to an ultra lightweight magazine setup, that is both more enjoyable and economical than buying the gas mags.

There are a number of factors involved when designing a HPA adapter for this gun. We’ve taken the time to address these, ensuring flawless feeding, lifelong air-seal, and an excellent aesthetic.

PLUG AND PLAY - We've injection moulded our own gas router for this adapter, and combined it with our high flow valve and printed feed lips. This means no more donor mags!

DO NOT EXCEED 150PSI WITH ANY AIRSOFT HPA ADAPTER.
ALWAYS USE AIR REGULATED BY A SECONDARY REGULATOR (EG AT200, WOLVERINE STORM, POLARSTAR MRS).
CHECK YOUR PSI BEFORE CONNECTING AIR TO A HPA ADAPTER.
NEVER CONNECT OUR EQUIPMENT TO PAINTBALL AIR TANKS OR CO2 TANKS.
NEVER CONNECT OUR EQUIPMENT TO A TIPPMAN STYLE HPA LINE

AIRTAC Adapters

Each of our adapters is designed to be low profile while reaching field limit FPS. We design and manufacture all of our products to the highest standard, and do not charge extra for ‘premium’ features. Where applicable this adapter features:
  • Lifetime Warranty (Our adapters have to be built to last)
  • Injection moulded or CNC magwell that is impervious to BB strikes at point blank skirmish FPS.
  • CNC or Injection moulded Feed Tubes and Magazine Catches for lifelong durability.
  • Tuneability/compatability via integrated shim systems. Our adapters are designed to cope with 'airsoft tolerances'
  • Gas Routers injection moulded from NBR, 1:1 with the factory gas router.
We test every HPA adapter we sell
  • Seal Test
  • Firing test, for feed and recoil (we have over 100 guns on site for testing)

Plug and Play

This adapter is ready to go out of the box. Valve, feed lips, and gas router are already fitted to the adapter. You do not need to use any donor parts.
No assembly is required.

Key Information

  • We use a US Foster Fitting as standard. This is the most common airsoft HPA fitting. EU fittings can be purchased separately.
  • Some of our HPA adapters have a smaller internal volume than gas magazines. Because of this, you will need to use a PSI of 90–150.
  • If you need higher FPS, you can:
    • Fit a tighter barrel
    • Use a longer barrel
    • Use heavier BBs
    • Fit an improved hop bucking
  • If your replica has an NPAS fitted, we advise opening it fully.
  • Do not exceed 150 PSI. Many airsoft guns will not see an increase in FPS past this, as the hammer may struggle to depress the valve correctly.
  • Insert the HPA adapter with your bolt / slide locked back to minimise pressure against the nozzle loading arm.
