After owning my mac11 for about a month or so, the cylinder broke off right after firing for about the fifth time. I sent it back to KWA and they replaced it and it worked for another few months. now on to the problem.
Now, once i fire it, mag full of bbs and gas, it jams 1 bb imediately every time.The bolt travels all the way forward and stops there, as if their was no gas in the mag. (the position it is in at this point will be the first picture.)
Once removing the mag, and pulling the bolt back, there is a bb stuck right at the begining of the barrel (this is the second picture). No gas comes out at all. keep in mind it does not just roll right through either end, it is simple stuck and pretty much needs an unjaming rod to get it out.though just blowing at the other end will get it out.
I use clean good 0.2 bbs, (and have tried several other brands) So i do not think it is the bbs. I have also taken the gun apart and lubed it with silicon oil nicely so i do not think this is the problem either.Also i have tried turning the hop up all the way down and all the way up.
i have taken out the hop up bucking, complete rided it of any oils whatsoever, out it back in. and it worked for two bbs then it jammed again. so i tried putting on some silicon oil, but it did the same.
Any gueses or ideas on how to fix this would be greatly appreciated.
