Kraken Ak-47 is jamming

[Turnbull]

Spellcheck ftl? Anyways, chill out there buddy. The reason this is called the Newbie Tank is so people can ask questions and get responses without people priming the flamethrower... No big deal, maybe he just wanted to say that for him those bb's worked well.

I noticed, since i own a kraken as well. Is that most of the time when i use bb's from different companies they all have a different styles of making 'em....did your kraken come with bb's that were labeled by whatever company they were from? ex: airsplat.com or airsoftgi.com
if so then i would recommend buying bb's from that webiste/store.

His point was that he disagrees that it's the bb's. As do I.

They aren't the best but they aren't fucking square and gonna jam it every 2 shots.

Actually my piont was that I could Identify the bbs I used and had success with. Perhaps the jamming is due to another brand of bb walmart stocks (lasersoft). I have used the arctic white in my stock guns that shoot under 350 fps with success. They are Bios and do not have a polished surface.
I have purchased Bios (0.20g) from my local shop that are made by cybergun as well, they are green with no polish and the same count (5000) at double the price. They say on the package guaranteed not to jam.
To this date I have not seen them perform any different than the arctic white from walmart (that is when I can see them). Tested today alongside the arctic white and velocity arms 0.20g polished at 60ft. Similar operation in its accuracy (same groupings), only difference I noticed was that the Bios had grouped a little higher. Either I was positioned a bit off or perhaps the bios get gripped by the hop-up differently.

On a side note, my 400fps rifle only gets fed 5.97mm +/- 0.001 0.25g bbs just to ensure it will perform properly. I use the walmarts when under 350fps and stock barrel. It is important to give your investment the best in parts and ammo to keep repairs from being frequent.

Well I would only imagine the hop-up gets a little more bite on them.

My breathing was off for one grouping and so could have been my form, but I did the velocity arms after the Green bios and after the white bios and then both bios in succession. So it just being 60 ft the whole idea for me was how the grouping would look. And everytime it was identical, well close enough. Hard to say why cyberguns bbs wouldn't work in a stock aeg, they don't make the worst products.

Krak'it open and see if the nozzle's damaged or slipped off the tappet plate.

Ensure your hopup is completely off (the slider should be all the way forward) when testing. With it off...the barrel should not be obstructed by anything. If the hopup nub is pushing down into the barrel while the hopup is off (a little, little bit is ok...but not a lot) then you've got to look at the nub, rubber, hopup unit. The edges of the hopup rubber should be evenly seated and not buckled or twisted in any way.

With the hopup unit/barrel assembly out of the front end...drop a bb into it. It should sit on the edge of the hopup rubber. A slight push with something ( (an allen key works) should pop it past the lips of the hopup rubber and it should just roll down the barrel on it's own. Try a bunch of BBs....if they all go through...use those to test with. If they jam...toss the whole bunch of them.

When reassembling...make sure you don't have the wires jamming up the front of the mechbox and receiver/hopup. That will push the mechbox back and cause an air leak. The ring around the hopup unit should sit flush and tight up against the mechbox shell.

Best of luck,

My buddy has a kraken and it was jamming - I tore it down to the barrel and hop up to see why it would be jamming and everything seemed fine. Lubed and cleaned it, put it together and everything seemed fine, firing about 50 rounds with no jamming.
The next day, it jammed. I figured it might have been the mechbox, but on a whim I tried a fully charged battery and he’s had no jamming problems since…

this helped a bit.i charged the battery up a bit and it worked better but not very well. So i bought some king and arms 70 round mags and now it works perfect.

Alright so if I use BB Bastard .20 bb.s It will NOT jam at all. Casue I had the same problem cept I got them at Bass pro, These exact same ones, they jam all the time, so ill seel them to my friend with a gun that has less Fps, it works in his, It would work sometimes but Keep Jamming so I was wondering if i should get BB bastard. Thanks

Bad BB's = Jam

BB Bastards = Good BB ---> BB bastard = No Jam
