Is my airsoft replica compatible with the Infinite V4 conversion kit ?

I. Built to Glock Tokyo Marui magazine standards, the Infinite kit fits many models—such as the AAP‑01, G17, G45, G19X, P80 and other similar pistols. Its flexible shim adjustment system lets you precisely set the kit’s height, providing universal compatibility and a perfect fit on every replica.

Important:

• The Infinite kit is not compatible with compact Glock models such as the G42, G26 or G19.

• For replicas other than the TM G17 Gen4 and Gen5, a small modification is required to route the HPA hose through the “lower frame.” This tweak is simple to perform and poses no risk to the replica.

• An optional cutting template is available for purchase or download to make this operation easier. It was designed to preserve the model’s integrity while ensuring a low‑profile setup that stays true to the Infinite kit’s spirit.

Compatible examples:

• AAP‑01 / AAP01C

• G17 Tokyo Marui Gen4 / Gen5 (Drop‑in)

• G17 We‑Tech Gen5

• G17 VFC/Umarex Gen5

• G45 VFC/Umarex

• G19X VFC/Umarex

• P80 PFS9 Janus Division

II. If your airsoft replica doesn’t appear on this list or is heavily customized with parts from multiple manufacturers, that doesn’t necessarily mean the kit is incompatible. Given the huge variety of Glock‑style replicas on the market, some models may require specific adjustments. In such cases, a few user adaptations might be necessary.

How to check if your replica is compatible with the Infinite V4 conversion kit:

There are many brands and generations of Glock‑style replicas available, each with its own specifications. Because of this variety, we’ve put together a guide to help you determine whether your replica is compatible.

Required tools:

• Vernier caliper

First, make sure your replica meets all of these criteria:

1. Your airsoft replica must be 100% compatible with Glock 17 gas magazines (Marui, WE, AAP-01, VFC/Umarex)
2. The back wall of the frame must have a thickness between 1.90 and 2.2 mm (see image 2).
3. The depth for the magwell must be greater than 3 cm.

Important:

Always wear safety glasses when handling airsoft products.



1. Your replica must be 100% compatible with Glock 17 gas magazines (Marui, WE, AAP‑01, VFC/Umarex).



2. The rear wall thickness of the frame must be between 1.90 mm and 2.20 mm.

If in doubt, email photos of your lower frame taken from different angles. That will allow me to provide precise, personalized assistance.
