Compatibility

  • WE
  • Tokyo Marui
  • Novritsch Raven
  • Vorsk
  • Tokyo Marui (If magazine uses screw not pins).

When paired with the magazines above, this adapter will work with nearly all airsoft Hi-Capas.

AEG Magazine Compatibility

AirTac recommend the use of a PTS brand magazine such as:

  • EPM-LR
  • EPM1RX
  • EPM-1
  • EPM1S

Many other brands of magazine will work. If a magazine does not fit, you can swap the rear shim at the back of the adapter.

AirTac do the legwork and make sure they test every adapter before they hit the shelves.

  • Seal Test
  • Firing Test, for feed & recoil

Lubrication & Sealing

This HPA Adapter is made of polycarbonate. One of the most impact resistant plastics. When sealing your adapter use only 100% silicone oil. Silicone oil mixed with petrochemical solvents (often 'spray-on' type), or superglue / cyanoacrylate, will destroy the polycarbonate. Your adapter will last a lifetime if you use only silicone oil. If for any reason you need to attach something to your adapter, use an adhesive compatible with polycarbonate such as "Loctite Super Glue All Plastics"

M4 Adapter Information

  • Injection moulded from polycarbonate, this magwell is near indestructible!
  • Compatible with most airsoft M4 magazines.
    • We recommend EPM1/EPM1s magazines as they have excellent fitment and strong springs.
    • Magazines advertised as Fast Feed such as the original EPM or Amarok magazines will also work well
  • BB retention means only 2-3 BBs are dropped when changing mag
  • A swappable rear shim is included

Please note only 2 screws are required to attach the modular magwell, some adapters may have more

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
