Thanks for your help guy, I think my best bet is to get another magazine. Then I can at least suss out whether the problem is within the gun or not. If not, I have a second magazine, not a bad thing. If anyone else knows whether or not the gold part in the above photos looks busted please let me know. Thanks for all your replies people

Unfortunately my sausage fingers won't reach the pin but I had a good look down the mag well with a light multiple times and i'm pretty certain the firing pin is moving backwards out of the mag well and stays flush with the side when the slide is back. I took some photos with the flash down the mag well and I noticed something that doesn't look right to my noob eyes. The gold "thing" in the photo almost looks sheared and torn? Is that normal?

Sorry for my late reply guys. I have taken a few photos of the different sides of the magazine. When I push an empty mag in there is no resistance to speak of and clicks nicely into place. Annoyingly, my friend took my bottle of gas home with him so I gotta wait to make a video showing you guys exactly what happens! It must have something to do with the valve as it starts firing as soon as the magazine clicks into place. Really annoying as this is my best sidearm!

Does anyone know what could be wrong? Please?

Hi guys, This gun is firing off a full magazine without me even pulling the trigger. It is as soon as I put the magazine into the gun it just goes off full auto. Pretty dangerous! https://youtu.be/YXQFKTpfFC8 I'm not sure if that link will work but it is me shaking the magazine. It makes a clinking sort of sound like something is loose. I thought I would ask here first before going to my local gun shop after some great advice from these forums regarding another gun I was having problems with. Hopefully someone knows what is going on! Thanks, Chris

Thank you for your replies, I will try this out tomorrow. I have been looking for a long time, not continuously but I didn't know it was a generic sort of thing. Sorry for the noob post but I really appreciate your long, detailed replies. I haven't used the gun since it made those noises and I didn't let it do it too much so hopefully it will be ok. Again, many many thanks guys!

I have had my CyberGun Colt M4-A1 for quite a few years and the other day while shooting I noticed the grip had come loose and it seemed to be affecting the performance of the gun. It kept making horrid noises like jamming and wouldn't fire. I could kind of feel it in my hand while holding the gun. I have stripped it and checked for clogged BBs to no result. I am convinced that having the grip loose if causing some kind of malfunction within the gun. I have attached a photo of the diagram at the back of the booklet and it appears there is a spring in there. Could anyone help me in determining how to fix this please? I have searched throughout the internet for months trying to find information about it, using everything including the reference number but can't find anything to help.
