What's new

The most complete HPA conversion kit for Airsoft pistol GBB is back with several improvements.

Drop in Tokyo Marui

The Infinite V4 kit is now 100% compatible with the Tokyo Marui G17 Gen 4 and Gen 5.

Ultra-simple “drop-in” installation: it mounts directly into your airsoft replica with no modifications needed.

For older-generation Tokyo Marui Glocks (excluding the TM G17 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 replica. An optional cutting template is available to make the job even simpler.
Universal compatibility

Equipped with an improved mounting system, the Infinite V4 kit delivers universal compatibility with models like the AAP-01, G17, G45, G19X, P80 and other similar Airsoft replicas. Its flexible fit, using shims lets you fine-tune the kit’s height for a precise, perfect fit on every pistol.

For 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 replica. An optional cutting template is available to make the job even simpler.
Optimized responsiveness

A new output valve, positioned as close to the firing pin as possible, enables faster opening and improved airflow on every shot, delivering 0.7–1.71 J depending on BB weight and operating pressure (PSI).
Even more resistant

The kit's clamping system has been improved: it now uses steel nuts, providing better resistance.

An innovative HPA kit.

Don’t just fire BBs, live airsoft to the fullest!

Discover Infinite, the first HPA conversion kit designed for GBBs, the most compact and realistic platform in airsoft.
Thanks to its innovative "Split" design, it removes all the limitations of classic GBB magazines without ever compromising the feel.

Fully mechanical, with no FCU or lipo battery, Infinite delivers stable and instant power.
It gives you the best of all three worlds: the authentic feel and ultra-compact format of a GBB, the consistency and reliability of an HPA system, and the practicality of an AEG, for total immersion and a greatly enhanced gameplay experience.

Take a Closer Look.

G17 split magazine - Ultra light 3D MJF

Powered by HP MJF technology.

MJF technology

Design without limits.

Creating a magazine that meets all these criteria was one of the biggest challenges of this project.

To achieve it, choosing HP MJF technology was an obvious choice. Used in demanding industries such as aerospace, automotive, and robotics, this process allows the Ultra Light magazine to combine precision, lightness, and durability like never before.

Simple and effective

Ultra-light and durable.

Thanks to their minimalist design, stripped of any unnecessary parts, the magazines reach a record weight of just 20 g while maintaining remarkable strength.

Their extreme lightness allows them to absorb impact energy better, making them stronger and more durable, especially during drops.
Less mass = less damage, scientifically proven.

Strong and durable

Tested, proven, approved.

Tested in real gameplay situations and subjected to rigorous trials inspired by the MIL-STD-810G military standard (Method 516.6): rapid reloads, repeated handling, successive drops, the magazines have proven their resilience.

The result: they withstand drops exceptionally well, where heavier metal GBB magazines get scratched, bent, and require careful handling due to the gas inside.

Even more possibilities.

Why stick to just one playstyle when you can switch modes effortlessly?

M4 / MP5 adapters

More BBs

Get a major advantage: you can also use your AEG magazines thanks to Split adapters.
In an instant, swap in an M4 or MP5 Split adapter to greatly increase your BB capacity and gain the upper hand in your airsoft matches.

Modified AEP Magazines (Limited Edition)

Aep custom

And that’s not all. The Infinite kit is now compatible with modified AEP magazines. To ensure perfect fit with GBB replicas, each original magazine has been carefully machined to create a precise notch. Without this modification, this adaptation simply wouldn’t be possible.

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
Is the kit installation Drop-in?

Yes, the Infinite V4 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.

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 1.5 mm
G17 gen 5 VFC/Umarex 2 to 2.5 mm
G19X / G45 VFC/Umarex 2 to 2.5 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.
