K120 Feeding Problems
Posted 02 October 2012 - 07:09 PM
With the gun straight up and down in a normal shooting stance, I'll only get 2-3 BBs before it starts dry firing. Sometimes it will shoot more, then stop for a couple dry fires, then start going again. Most of the time though, it just stops after 3-4 rounds. I was thinking it was the magazine jamming at first, but I'm not so sure about that.
I can turn the gun upside down and it feeds the entire magazine flawlessly. I can also just hold the BB retention clip back and the entire contents of the magazine flies out.
I'm not sure what to do. I've completely disassembled the magazines, cleaned them with soapy water, and made sure that I have a little bit of lube on the BB track.

I think I've pretty much shot dead whatever warranty I had. I've painted it, thrown on a mock suppressor, installed a 3/4 cylinder, and did a nice shim/grease job.
I'm using ASGI .20's

Even if under warranty it'll cost you $5 to send the magazine in for repair. As I recall these are only $10 each to start with.

I mark all my magazines with a white "R" on the bottom with automotive paint, this wouldn't void my warranty would it?

I purchased them on October 2 from airsoftgi.
(ironic because it looks like that's the day this post was started.... Maybe its just bad juju! Haha)
Should l clean them or should I just send them back??

1) Have you accidentally left rounds in the magazine? I.e. loading them and then storing them without unloading them before storage. by not unloading you run the risk compressing the spring and then have it shorten because of the compression.
2) what kind of BB's are you using? sometimes if the BB's are just slightly larger than normal, it happens, the bb can slow/jam the follower causing it to not properly push the bb's up into the gun.
3) Have you stretch your spring? On my old MAG magazines when I wasn't feeding I would take the spring out and give them a stretch by pulling on them by a little bit to make it just a little longer/return them to size because I left the magazine loaded in storage.
Worst case scenario you can always contact us on the help desk. And since it is a magazine, you can most likely ship them in a flat rate envelope for cheap.

Once I was able to test them I realized I had feeding issues... I figured it was a gun problem at first. But after numerous testing with other mags I have realized that I only have these feeding issues with these k120 mags.
All my non kwa hi-caps fees perfectly! But all 6 k120s are having issues with feeding. And all at random..... But will never get through even half the mag before the firs dry fire. But the minute you turn the gun upside down they start feeding instantly again.
Is this something I should send back to kwa or back to airsoft gi?
I'm assuming at this point that I just got a box of bad mags.

I knew you guys would ask me what bbs I tried with them so I tested 1 mag with every brand of bb I could find in the house! All the same problem!
And yes I realize I have way to many different brands of bbs floating around! I like testing different brands out to see what works best for me.

I have good an bad news regarding my k120 mags..
Good news.. They work...
Bad news.... Not in my sr-12!
I don't know if it's a feeding ramp issue or something else, but my sr-12 just doesnt like these mags!
At first my m4 was having issues as well but now will fire through every k120 mag without any issues!
I've even gone as far as taking out the barrel and hop-up from the sr-12 and put it in my m4.. And the mags fire fine!
At this point I figured it was a issue with the feeding ramp. So while the barrel was out of the sr12 I decided to put a full mag into the lower half of the receiver to see if any bbs were getting caught up on the ramp...
Nope! All the bbs shot straight up and bounced off the ceiling... With every mag!
So now I'm totally stumped!
It's not a Mag issue because they work in my m4.
It's not a hop-up issue or bucking issue because te mags fire through both barrels when put into the m4.
So the only thing left is the feeding ramp right?? But it doesn't seem to be blocking the bbs path in any way.
What is my next step of troubleshooting?
