I have been having some serious problems with my kwa.
Originally I had the left/right accuracy issues and an ineffective hop up. I got both of those issues resolved by replacing the h-nub and I realized I had some debris in my barrel. So I was happy with my accuracy and my hop up.
Then one day I was putting my battery in and accidently  dropped the battery. It ripped out the red connector to the fuse, me and my dad re-soldered it back on. I know the solder was good so I wasn't to worried about it.
About a week later my gun starting having a lot of miss fires and firing two bb's at the same time. (shooting excel .25's) This problem was completely random and was often fixed by taking out the mag and putting it back in.
On Friday night I was shooting the gun a little bit out in the backyard making sure it was ready for the event on Saturday when all of a sudden I hear a single gear spinning. I go back inside and take out the motor just in case it was a misalignment. When I put the motor back in, I made sure it was in completely correct, the gun did absolutely nothing when i pulled the trigger. I check the fuse and the fuse was blown. I replaced the fuse with a 15A glass fuse and it still does nothing. We check the motor and it is not working. Something inside the motor was grounding out. We replace the motor with one from another gun, and we get back to the original spinning gear problem. I decided that I wasn't going to bother taking the gear box apart, I would let the tech's at the event deal with it. When all was said and done they replaced the piston and the bevel gear.
I still have a dead kwa motor but atleast a working gun.
-Was this user error even though I put the motor back in correctly, and didn't touch the gear box (only fired ~8-10k shots). The only time the gear box was opened was a month before to downgrade the spring (does downgrading spring void warranty?) Is there anything I can do besides buy a new motor? Is it still covered under warranty.

Try lubing it with some silicon lube or try other M4 magazines.
If that doesnt work, split your gun inhalf and shoot and see if the air nozzle full moves back and fully forward. If it s
It could be a tappet issue but I doubt it since its not a common issue in KWA's from what I have seen.
If that doesnt correct it, see if your bucking and barrel are seated properly in the hop-up unit and put a drop of lube in there too. Also see if your hop-up is turned on too much which can cause jams and/or missfeeds. Ontop of that clean your barrel.
Also make sure you have the little spring on the front of the hop-up unit and the unit itself is correctly placed in your gun.

If those battery of tests/solutions dont work, call KWA and send'er in. If I missed something post up!

Did your shell crack? I mean it was cold outside and it could happen in the cold.

I didnt even read all the original post :lol: I just saw the misfire/double feed issue so I tired to solve it!

If the GB was cracked the techs at the event would have said something.
Your warrenty is done, opening your GB voids warrenty, that and you downgraded the spring and thus had to remove OEM parts. Good news is that you can still pay to send it to the tech's at KWA to get it repaired.

P.S. There is a sticker on the GB, you can see it from the magwell of the gun, it says "Do Not Remove" or something along those lines.
