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.
MP5 HPA Adapter Info
This magwell is made of CNC aluminium and cannot be damaged by BB strikes.
Compatible with all CYMA MP5 Mid Caps (65 round metal, 120/130 round metal, Straight, Novritsch Straight, Bullet Window).
BB Retention drops only 2 BBs when changing magazine
Fitment Instructions: This magwell has a rear shim and a feed tube spacer. The feed tube shim fits under the feed tube. The rear shim is held in by two screws.
Straight Magazines (Default Config) - Keep Shim In. Feed Tube spacer necessary on newer CYMA MP5 magazines
Curved Long / Short Magazines - Remove rear shim. Keep Feed tube spacer in.
If straight magazines will not feed with the rear shim and feed tube spacer installed, try removing the rear shim.
In the very rare case short CYMA magazines do not fit your adapter, contact support@AIRTAC.me (we can solve this for you ASAP)
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.
