Primary Airsoft GLOCK Gen4 M4 HPA Adaptor

This one fits the Glock Airsoft Pistol.

From the manufacturer:
Our 4th generation Glock M4 adapter is injection molded from a strong glass-reinforced nylon material.

The magazine release is now CNC machined aluminum for all Gen4 Primary Airsoft adapters. 

This adapter allows you to use HPA (high-pressure air) and M4 AEG magazines on your Glock airsoft pistol. To use it you will also need an M4 AEG magazine, a “paintball” tank with a low-pressure regulator (0-140psi), a hose with a Foster (PolarStar) quick disconnect, and of course bbs. The normal operating pressure for green gas is roughly 120psi depending on the temperature. We recommend that you run your pistol near this pressure and do not exceed 140psi. Keep in mind that higher pressures can cause excessive wear and damage to the internal components of your airsoft pistol.

We recommend that you use high-quality M4 AEG magazines with strong springs for the most consistent performance.  Do not leave your magazines loaded with bbs for an extended period of time as this will cause the springs to fatigue and lose performance. Worn-out AEG magazine springs should be replaced with super-feed springs.

The adapter now comes with a longer screw which has a 2.5mm hex head. They also come with our new universal feed tube that will fit the following magazines:

  • WE tech / Armorer Works G17 magazine
  • Tokyo Marui G17 magazine
  • Action Army AAP-01 magazine
  • Guarder Aluminum Magazine Case for G17

The adapter will work in an Elite Force Glock, KJ Works, or SSP18 if installed onto a WE, AW, or TM G17 magazine. The adapter will not fit onto Elite Force Glock magazines, KJ Works magazines, or Novritsch SSP18 magazines.

The metal quick disconnect fitting in the photos will come installed. The fitting is a US standard Foster Pneumatics 1/8 NPT quick disconnect. The fitting can be changed to any fitting that has 1/8 NPT threads. Be sure not to cross-thread the fitting when installing a different one. The adapter does not come with a gun, magazine, or any other accessories.

The adapter was designed to even the playing field when playing airsoft with a pistol as a primary against AEGs with hi-cap mags.
