In fast-paced games like airsoft and paintball, even a two-second delay can mean the difference between hitting your target—or being taken out. That’s why having immediate access to CO2 cartridges matters. The CO2 Cartridge Holder keeps your spares secure and within reach. Let’s walk through how to set it up for maximum efficiency.
In this tutorial, we’ll walk you through how to install, load, and use your CO2 Cartridge Holder, step‑by‑step.
Step 1: Unbox and Identify Your Holder
When you open the package, you’ll see the holder body and the mounting hardware. Depending on your purchase, it can hold 3, 4, or 5 cartridges.

Step 2: Determine Your Mounting System
The holder is designed to mount on one of three major systems:
-
Picatinny Rail
-
M-LOK
-
KeyMod
Check which system is on your firearm, airsoft rifle, or paintball marker. This will dictate which screws or locking plates you use.
Step 3: Position the Holder on Your Rail
Decide where you want your cartridges mounted. Common placements are the side rail and the underside rail. Once you’ve decided, align the holder with the mounting holes.
Here’s what to consider when choosing the placement:
-
Side rail - for easy thumb access mid‑game
-
Underside rail - for balance and low profile
Step 4: Secure the Holder
Attach the correct hardware (mounting clamp, M-LOK nuts, or KeyMod locks). Once attached, insert screws and tighten using the included tool or a small hex key. Lastly, test for stability by giving it a light shake.
Tip: Don’t overtighten. Keeping it snug is enough to hold firm without stripping screws.

Step 5: Load Your CO2 Cartridges
Push each 12‑gram cartridge into the slot firmly. Make sure the cartridges sit flush as this ensures a secure grip. Then, test by tilting your marker. Cartridges should stay locked in place.
Step 6: Use in Gameplay
Once everything is set and loaded, simply pull a cartridge straight out when it’s time to reload. No more fumbling through pouches or gear because you’ll always know where your spares are. The lightweight design means no bulky feel or distraction during action.
