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.
In the world of Airsoft battles, you cannot play around like that when you need for your new gun to work the 1st time you pull the trigger, Anyone who knows the relationship between Gas Pressure, Liquid & ambient Temperature can easily tell you what gas that you should use for your gun to work correctly. Green Gas & Propane have the same Gas pressures, & the only lower pressure Gas that you could use is 134A refrigerant, which I believe is in the bottles of Gas Duster (that Kids Huff to kill their Brain Cells with because the refrigerant displaces theiir oxygen and nearly kills them),
If the Gas relief Plunger is the problem, then if you push your plunger relief valve in when there is no gas in the magazine, and you have resistance then that is the problem, but I bet that you do not. I'm writing you this because I bought mine from Evike, who I happen to really like,except for their WArranty where, I pay the shipping cost to get it back to them for warranty. NOT SO, in this case because I explained my problem in detail and with Gas characteristics knowledge. Now think about shooting your gun when its hot outside. How do you think your M11A1-NS2 will work when its 90 deg F outside, because Gas Pressure rises proportionately.
My Suggestion is that you NOT fool around with the gun and wait another day. You would be better off by not guessing every problem and call KWA Tech Support and tell them exactly what happened with your M11A1-NS2 & that there are others out there with the exact same problem & that it probably warrants a recall & you may get them to fix it without charging you $35 an hour.. The real problem is that there is a problem with the piece down in your gun that pushes the plunger in. The BB sticks in the Hopup, because there is not enough Air pressure getting to it to shoot the BB out.
I do not know about you, but I can't blow $140 on a Gas Blowback gun and just use it as a paper weight, because you will get killed in battle with that thing as-is. One more thing I forgot to mention & that is the EVIKE Team that I am currently dealing with has been very responsive to my problem within a day each time & have even told me that they will have to Break the Gun down twice to fix the problem. Now what Tech guy would ever tell you that?
Good Luck & Best Wishes,
