An innovative HPA kit.

"As players, we all know that GBB(R) replicas are still the benchmark when it comes to realism and shooting feel.
But they do have one weak point: the magazines. Price, weight, limited gas capacity, cooldown, leaks... all these constraints can get in the way of the experience..."

Frequently asked questions

Why choose Infinite over a conventional electro-pneumatic HPA system?

Infinite is the first HPA kit designed for the GBB platform, the most compact and realistic in airsoft.
Unlike electro-pneumatic HPA systems, it requires neither FCU nor battery: everything is mechanical, simple and reliable.
You keep the recoil, the end-of-magazine firing stop and all the fun sensations of a GBB, with the regularity and power of the HPA.
And all this at a much more affordable price than traditional HPA systems, which often cost between €300 and €700.
Infinite is ideal if you are looking for an ultra-compact, high-performance primary or secondary airsoft replica capable of making your games more intense and immersive.

Classic HPA system:

❌ Long and complex installation
❌ Requires FCU and battery
❌ High price (€300 – €700)
❌ No feeling when shooting

With Infinite:

✅ Easy installation
✅ 100% mechanical, no electronics
✅ Realistic sensations (recoil, stopping firing at the end of the magazine, etc.)
✅ More compact, more fun, more immersive
✅ More affordable price
HPA adapter vs Infinite ?

The Infinite kit is designed to preserve the original GBB experience while providing the consistency and performance of HPA.
Unlike standard HPA adapters, which often sacrifice functionality and realism, Infinite retains:

  • A functional slide stop with empty magazine detection
  • The original position of the magazine release button
  • The ergonomics and handling of the original replica
  • A compact, low-profile design, visually identical to a standard gas magazine once installed

Additionally, the Infinite kit is versatile, allowing the use of AEG magazines through optional modules.
The goal is to combine performance, immersion, and realism, while giving players the freedom to choose according to their preferred play style.
Is the kit installation Drop-in?

Yes, the Infinite is designed for perfect compatibility with G17 Tokyo Marui Gen 4 and 5.
This means the conversion kit can be installed straight in, with no modifications needed on your Airsoft replica.

However, for the AAP-01 and Airsoft Glock replicas (except G17 TM Gen4 and Gen5), a small modification is needed to route the HPA hose through the lower frame. The procedure is quick, easy, and safe for your Airsoft replica. An optional cutting template is available to make the job even simpler.
Is the Infinite Kit compatible with the AAP-01(C)?

Yes, the Infinite kit is fully compatible with your AAP-01. Thanks to its universal design, it fits a wide range of Airsoft replicas.

To easily install your Infinite kit, follow the complete guide available here: Installation Guide .
Is the HPA coupler included with the Infinite kit?

No, the coupler is not included directly, as there are several standards (US, EU, MINI).
Leaving the choice up to users allows the kit to be adapted to each configuration and avoids imposing an accessory that would not suit everyone.

If required, the coupler can be added from the “HPA Fittings” section of the site.
The kit is equipped with an output to a 6x4 mm line (standard in HPA), compatible with US, EU or MINI fittings.
Which magazines are compatible?

The INFINITE HPA kit is all about adaptability.
It keeps that authentic GBB feeling: the kick, the sound, the realism but gives you the freedom to customize your setup however you want.
Whether you’re going for high capacity or full milsim immersion, there’s a magazine built for every playstyle:

-Milsim Magazines: Designed for full immersion, with a discreet, lightweight design. Enjoy all the GBB feels: blowback, slide lock on empty, natural handling… Don’t just shoot BBs, experience airsoft in a more realistic, fun, and intense way.

-M4/MP5 Adapters: Perfect for players who prioritize capacity, using AEG magazines holding over 100 BBs. A great solution for those willing to sacrifice some realism and GBB handling in exchange for maximum ammo in-game.

-Modified AEP Magazines (Limited Edition): Ideal for players looking for a balance of discretion and versatility, with adjustable capacity from 30 to 100 BBs, though without the empty-mag slide lock feature.

⚠️ If you choose the AEP option, you will need this specific cap to use them with your Infinite kit (not compatible with V1 and V2): 👉 Infinite AEP Cap .
To ensure optimum compatibility with GBB replicas, a notch has been carefully machined onto the original CYMA AEP magazines (without this process, this simply would not have been possible). AEP TM and SSE18 Novritsch magazines are also compatible, but will require the same notch to be machined.

The easiest and quickest HPA kit to install.

You can turn on subtitles in the settings and select your preferred language.

VFC: G17 | G45 | G19X | G18C
Janus Division Group: P80

Shim recommendations:

To achieve a perfect seal with your replica, you can easily adjust the kit using the shims already installed on it.
This system has been designed to be as simple as possible: thanks to the height adjustment, you don't have to worry about small tolerance differences between parts.
The kit thus fits many Glock-type replicas, including custom models.

And to make things easier for you, you can simply use the shim configurations shown in the table below.
The configurations presented serve as a reference: you can of course modify them according to the tolerances or specificities of your replica.

(Shim adjustment must be done on both sides, using the 0.5mm and 1mm shims provided.)

G17 gen 4/5 Tokyo Marui 2.5 mm
AAP-01 1 mm
AAPC 1 à 1.5 mm
Cthulhu Lancer Tactical 1 mm
G17 gen 5 VFC/Umarex 2,5 to 3 mm
G19X / G45 VFC/Umarex 2,5 to 3 mm
P80 Janus Division 2,5 mm


Remarks :
If you add too many shims, it will block the replica cycle.
Conversely, if there is not enough, the attachment will not be tight enough and the cycle will not be complete.
Experiment to find the optimal configuration for your replica.
