Runs a TM Glock or AAP-01 from M4 magazines on air. Consistent shots, an adjustable and safe FPS, and a large air reserve behind you.

Gas pistols are hostage to the weather. Air is not. Running the gun from a regulator means the same velocity in January as in July, the same trigger response all day, and a magazine that holds rifle numbers rather than pistol numbers.

The same adapter covers both the Tokyo Marui Glock and the Action Army AAP-01, and Kross report good feeding on both. It is made in MJF Nylon 12 to take close-range hits.

Three packages: fit it yourself, have it fully assembled, or send in a magazine you already trust and have the work done on that.

The work itself is minor. Out comes the gas block seal from the base of your magazine, across goes the O-ring, on goes the adapter, and the long screw pulls it down onto the internal thread. Test it on air before you count the job done.

Frequently asked questions

What does HPA actually change? Velocity stops moving with temperature, the shot-to-shot spread tightens, and you can set FPS to a site-legal figure and leave it there.

Does the same adapter really fit both pistols? Yes. Kross build one adapter for the Glock and AAP-01 rather than two.

Which magazine should I use? Kross recommend PTS EPM1. It is the one they designed around.

Is an O-ring supplied? Kross say the O-ring is on them for this one.

💡 Titan Forge Airsoft tip: Set the regulator before the first game, not during it — chrono it at home and you will not be the person holding up the safety brief. See our HPA regulators.
