Introduction: CO2 Airsoft Magazine No-wrench Mod

Picture of CO2 Airsoft Magazine No-wrench Mod

One of my Airsoft guns is a HK USP CO2 pistol.

The way it is designed, the CO2 cartridge sits in the magazine. This is nice, because all you have to do to render the gun completely safe is remove the magazine.

The only problem is that it requires an allen wrench to take out the plug and change a cartridge. The wrench seems to get lost easily, so I did this so I wasn't stuck with just using the wrench.

Step 1: Tool

I used a Dremel tool with a cut-off wheel, but a saw or a determined person with a knife could do this easily.

Step 2: Find the Peice

Take the magazine out, make sure there isn't a cartridge in it (obv.), and remove the plug on the bottom.

Step 3: Cut It

Cut a notch across the wrench hole as shown. I wouldn't cut deeper than about an eighth of an inch. Clean up any plastic burrs around the cut when done.

Step 4: Screw It

Now you can use a coin, a knife, or pretty much anything that will fit in the notch and not break to change cartridges on your magazine.






Any Questions?  I do hope I made everything clear...

is there a way to buy just the plug?

Is that cartridge a kind of plastic? I've never used them so I don't know. I wondered if you could safely use a pair of sturdy lineman's pliers, hold the nickle over a flame until it is very hot, and then push it quickly into the slot area that you show, withdrawing it before it melts itself into the cartridge. You'd have to control the push force so that you did not overdo it! Just wondering. I have patched small holes in plastic containers, pet cages, etc. by flame-heating a penny and positioning it into place over the hole.

Thanks for sharing this great idea!

Oh, hey, that might work! This works too, but if someone didnt have a rotary tool, they could do that. The magazine is indeed plastic.
