• CNC or Injection moulded Feed Tubes and Magazine Catches for lifelong durability.
• Tuneability/compatability via integrated shim systems.

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.

Key Information

• Some of AirTac's 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, AirTac advises 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.

Novritsch SSP5 Users: AirTac highly recommend running an uprated nozzle spring to ensure good feeding through the whole magazine.

IMPORTANT

• 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 AIRTAC EQUIPMENT TO PAINTBALL AIR TANKS OR CO2 TANKS.
• NEVER CONNECT AIRTAC EQUIPMENT TO A TIPPMAN STYLE HPA LINE.
