Hello,

I just received my KWA M4A1 today. I shot two magazines through it with no problem and I was really impressed by the power and rate of fire of the gun. However, on my third mag the semi auto stopped working consistently. Now, every time I try to shoot semi, the gun makes a noise like the motor is trying to turn but is being stopped by something. Full auto works just fine, though. Also, semi works when I hold the gun upside down and shoot, and it also works for 1-2 shots if I shoot a burst on full auto just prior to switching the firing mode to semi. I am more than a little concerned about this, as I just spent $250+ on this gun and I have yet to actually use it in a battle. Any help/suggestions about how this problem can be corrected would be greatly appreciated.

EDIT: I just had another look at my gun and the semi will shoot, but i have to wait 3-4 seconds between trigger pulls. Also, it seems to sometimes shoot a burst when the switch is set to semi. I am not sure if the selector mechanism inside the gearbox is somehow messed up or what, but I am sure that this behavior is abnormal.

Where did you buy the gun from?!  

Neither way, it could be a disconnect issue.  Give us a call and we will take care of it.

Thanks I appreciate the response! I bought the gun from AirsoftGI. What is the number I need to call? Would you guys give me like a set of troubleshooting questions or something, or would I have to send the gun back? When you say disconnect issue, what exactly are you referring to? Once again, thanks for the response. I am impressed that you guys have this website where your customers can come and get help.

I had the EXACT same problem. WHen the gun is on semi it sometimes does full auto, and you have to pull the trigger very slowly. None the less KWA were very good about it, and I am shipping it off soon for repair. Ive only had it two days  :(
Oh well, excellent gun, and very well made.

Only gripe is that now I have to fork out another 35 dollars to ship it. Expensive gun this is turning out to be. Very much worth it though.

I really don't want to have to spend the extra money to send it back, so I'm hoping someone can recommend something to fix the problem. Even if they cant, I never really use semi auto, but I don't like the thought of my $260 gun not being fully functional. Then there is always the chance that the full auto will stop working too, and I don't really feel comfortable with that. KWA does seem very helpful from the threads I've read so far, though, so I don't think I have anything to worry about.

Yes I know how you feel. It's a little agrovating that I just spent $300 on this gun, only for this to happen. Now I have to go about a month without my baby.

Disconnect is also called the cut-off lever.  That's what's controlling the semi.  The only way to fix it is open up the gearbox, if you send the gun back to us, we can fix it for you under warranty.

Can you describe how to fix it? Do I need to replace the cut-off lever? As I live in Germany my M4 is semi only (modified selector plate I guess), could that be a problem too?

For obvious reasons I can't send it over to you guys ;)

OK thanks allizard! I have one last question: Does painting the orange tip black void my warranty? I can remove the black paint if it does and hopefully nobody will know, but I suppose this is important to know before sending my gun back xD. Also, I am going to use it in a game today, but that wouldn't affect the warranty, either, would it?

You MUST have orange tip on the gun when you ship the gun in for service.  Warranty or not.

And yes, you need to replace the cut-off-lever.  

If you are in Germany, where did you buy the gun from?!

Thanks alizzard, I guess I'll do that then.

There are some airsoft online shops in Germany.
Mine comes from sniperairguns.de

The guns in Germany come without the orange tip so I can't send it to you anyways :D

I am getting ready to ship my gun back in for repair. I know I need to call KWA to get an RMA number first, but I have one more question before I do that. I have removed the black paint I put on the orange flash hider, but there are still bits of the black visible in the holes on the top of the flash hider. Will my warranty be voided if a KWA employee notices that the barrel has been painted in the past? The orange is completely visible now with only little specks of black in the previously mentioned places. It is obvious that it was painted, but the orange is not obstructed. Anyway, please let me know if my warranty would still be good before I ship out my gun!

Try alcohol swabs or paint thinner and soaking the flash hider in it for about a minute then wipping the dots off with a paper towel. I used to do a lot of painting.
