I finally got the courage to disassemble and check the bucking on my KM4-CQB.  (The instructions here and the YouTube videos made by 13 year-olds was the final push.  :) )

The bucking was swollen and soaked in oil (I assume silicone).  Took finesse to gently remove it as it would not originally get out of the hop unit and just telescoped closed.  Finally got it out and soaked/cleaned/dried.  Slid right back in.

Not knowing just what damage if any was done I have a new KWA bucking on order.  But now that I know how to access the bucking in this carbine is there a better aftermarket unit I should consider that uses the stock hop up mechanism?

Is there anyway to clean the hop up without opening up the gun?

Not that I know of but it's dirt simple.  So simple that removing the AEG barrel is in the owers manual.  The only additional task is popping off the little clip that secures the hopup and bucking.

I personally recommend you get a new KWA bucking and have it on hand before doing this.  My bucking was hopelessly swollen and never did clean up.  A highly recommended "green" bucking had to be trimmed to fit and did nothing.  A new KWA bucking cured all my problems.

Cleaning or replacing the LM4 bucking is much more difficult.

Thanks Chuck! I have another 2GX bucking on hand if anything goes wrong.

Correct, it's considered general maintenance.

So I tried to clean my stock SR10 barrel last night with the cleaning rod that came with the gun and it will not fit in to the barrel. The head of the rod with the slit will fit but the point where that head attaches to the rod is too thick for the barrel. Am I missing something here?

Will it fit without any cleaning patch attached?

Hello,
I am a new KWA owner I recently purchased the SR10 model and I am very pleased I did a lot of research and happy with the purchase. I have only shot the gun once due to my schedule and it being so cold out at this time I have shot exactly 360 rounds. After shooting I noticed my range wasn't so good and the hop up adjustment did NOTHING when I tried to adjust. After reading these post and the manual it says this gun needs to be broken in. Would it be wise for me to remove grease build up in the barrel and hop up bucking thru warm soapy water or just shoot it out ? Or combine both? I want to make sure I'm doing the right thing and I also want to make sure there isn't anything wrong with the gun as it wasn't cheap. I am currently using the kwa mid caps and .25 g golden ball bbs. Please advise.

Congrats on the new kwa! It took me almost 7,000 rounds for my cqr to work well, but what you need to do is definitely soak your bucking in warm or hot soapy water over night do this about 2-3 times. Kwa says it will take about 5,000 rounds for your gun to start running smoothly. Also the bbs your using are just fine. These guns work so well that a couple times I had to use crosman bbs for a day and didn't wreck the gun.

Thanks for the reply should I soak it 2-3 times consecutively or every 1500 or so rounds ? I plan on doing this all this week or latest the weekend. Am I correct in saying that I do not need to remove the hop up gears just the plastic clip and the buckin should come right off ?

Hello,
I recently bought a new KWA M16, but am new to KWA rifles, or airsoft in general. I just had a few question and would greatly appreciate if someone could help me out. First of all where is the hop up bucking and how can I get it out? I have know idea what and where this is. Another concern I had about this method of cleaning is the fact that there is no lubricant or rust preventive coating left on the gun. Like I said I am new to airsoft and most of my experience is in actual firearms so I may be wrong when it comes to airsoft, but I know that on a gun especially on the moving parts oil or some kind of lubricant and rust deterrent needs to be applied. If you use water to clean your gun every time even if you do dry it, all of the internals will be grinding against each other and quickly wear out. Also if you live in a humid climate there is a very high chance your gun would rust without proper coating of oil. If not silicone what and how should I keep the moving and metal parts of my AEG clean and rust free?

As Chuck said, dont waste your time on the orig bucking. Oil and greased soaked. If your going to shoot .25 buy another 2gx, they should send us all one for free. They know buy now they had way too much grease in the box. Not many owners could just open the box and enjoy the gun. GOT TO TAKE MY NEW GUN APART? Go with a G&G bucking, and if flat hopped will get crAZY range. Love my SR10, after some minor tweaking with the hop up. Best gun I have ever owned.

  If you keep it in the house you will be good. Dont use any kind of rust preventive that is oil based. Most use silicone based products.
