One of the most common types of question I get on my Replica Airguns YouTube channel has to be something like… Why is my Airgun not working? Most of the time the amount of info about the problem is limited to something like… “It was working yesterday but now it’s not working anymore” or something like “when I pull the trigger nothing happens”. My personal favorite is… “I took my gun apart and now it doesn’t work!”
I just made a similar video for Blank Guns and as I said in that video, trying to trouble shoot a mechanical or technical problem over the internet is very difficult, this goes for cars, guns, computers or what have you…
In this Why is My CO2 Airgun Not Working video I will however cover some of the more common and obvious problems I have seen relating to why a CO2 Airgun may not be working properly. I really don’t get a lot of questions about Spring Piston or Pump Airguns so I will be focusing on CO2 Airguns in this video. There will be a lot of crossover with CO2 Airsoft guns so this video may be helpful for some of you Airsofters out there
First let’s get the super obvious stuff out of the way!
- Did you put a new CO2 cartridge in it and is it pierced all the way?
- Did you load BB’s or Pellets into the Airguns magazine and is the magazine in the gun correctly?
- Is the safety off?
- If the gun is a blowback semi auto single action Airgun then did you pull the slide back prior to the first shot?
CO2 Related Problems:
Not all CO2 cartridges are created equal, they often have slightly different shaped nubs on them and some brands will work better than others in different Airguns. If the shape of the CO2 nub does not fit properly into the valve area then it may not pierce or it could pierce but then not allow you to tighten it all the way losing all the CO2 in the process. If the CO2 is coming form the airguns handle to CO2 Valve area then this is an indication that your problem is related to the area where the CO2 enters the airgun.
There is a seal where the CO2 cartridge buts up to the valve, this seal can be damaged or even deformed from usage or even leaving your CO2 in the gun for too long. The outside CO2 Valve seal can also take the shape of a specific CO2 nub so when you use a different brand CO2 the seal may not properly make concat with the new CO2 type you are using, again causing leaking or even the total loss of all your CO2. Watch my YouTube video on “How to Fix Leaking CO2 in an Airgun”.
CO2 Valve Related Problems:
Again, make sure that Outside CO2 Valve Seal is in good condition and any leaking is not being caused by this problem, if you have checked the Out Side Seal and everything is OK with it then perhaps there is a problem with the CO2 valve?
One indication that your CO2 Valve might be the culprit is the total loss of all your CO2 when you try to insert and tighten a new CO2 Cartridge. Usually all the CO2 will exit the barrel, not the handle or valve area. What may be happening is the valve is stuck open or the internal seal is broken or deformed. If this is the case you will have to remove the valve and have a look inside, this is a lot easier on CO2 airguns that have the CO2 valve in the magazine, if the CO2 valve is in the actual Airguns then a lot more disassembly may be required and I would recommend an Airgun technician take care of this for you.
If the gavel is in the magazine then you will have to unscrew it, you may require a special tool for this? Once the valve is out of the magazine take a look inside and examine the internal seal, also look for any bits of metal shavings as they can disrupt the action of the valve causing leaking. Give the inside of the valve a good clean and then lubricate it with some silence spray. hopefully that fixes your problem!
BB’s getting Stuck in the Blowback Gas Tube:
I have actually made a dedicated video for this problem so I will put a link to it in the description of this video. The main reason people may have this problem is because we all like to rack that slide on our full blowback Airguns, but if you have a fully loaded magazine then each time you reach that slide without shooting the gun, you are inadvertently trying to load another BB into the breach area, the breach is only designed to hold one BB at a time so after a few racks of the slide the newly loaded have no place to go but into the Gas Tube where they can get stuck and cause having to the operation of your Full Blowback CO2 Airgun.
BB’s Rolling Out of the Barrel of Your CO2 Airgun:
This is not actually a fault of the gun but happens because of the way the gun is designed. This situation can happen with certain CO2 Airguns when the gun user pulls the trigger really slowly while the gun is point slightly in a downward position. What is actually happening is the first part of the trigger is made to draw a BB from the magazine into the breach of the gun. If the barrel of the gun does not have a rubber hop-up stopper in it then the BB is free to roll down the barrel and out of the gun. How do you fix this problem? Be more committed to your trigger pull and or shoot at a target that is not so low. Perhaps place your targets slightly higher than the gun so the barrel is not pointing down, especially if you like to take your time with the trigger :)
A Little Maintenance Can Go a Long Way!
Sometimes a good cleans is all you need to do to get things working as they should, again I have already made video Tutorial Showing “How to Clean Airguns and Blank Guns”.
What about stuff like My Airgun is jammed or my trigger is stuck or some random part fell out of my gun?
There is only so much I can cover in this video, most other problems are going to get a bit more complicated to fix and I suggest if your Airgun is not working and the suggestions I have made in this video do not solve your problem, then consider taking your gun into a gun tech.
