After taking it to my local airsoft store to get it fixed, my MP9 now works flawlessly on semi-auto. However, my gun miss-feeds like crazy when doing bursts on full-auto. Occasionally, the gun will start dry-firing for about four or five shots and then on the next shot, a bunch of bb's will all just simultaneously shoot out of my gun and go about 15 feet. This happens on both kwa/ksc .20g and .25g bb's. I've tried adjusting the hop-up and cleaning my inner barrel and the problem still comes up.

How have you cleaned the barrel and hop-up and have you used any silicone oil directly on the bucking?

Yes I have cleaned my barrel and bucking, and I have not used silicone oil on the bucking or the barrel.

They do this when the hop rubber swells from oil.. Take it out and clean it with hot water and dish soap, it will fix it right up.

Is it safe to do this with the bucking still in the barrel because I don't feel comfortable taking the bucking out of the barrel.

Give it a try and see, I am not sure how effective the cleaning will be but it wont hurt anything, just dry it out good when you are done.

Ok, I'll try it. How should I dry the bucking when I'm done?

Use hot water and dish soap, then blow it dry with compressed air.

See my thread below, I had exactly the same issue.  The bucking is not too hard to change if you follow the guide on here.  In the uk the part is only about £4, so might be worth changing as you will only have to strip the gun down once and you will be sure it's fixed.

Hi, sorry I haven't responded in a while. Once again, it works flawlessly on semi-auto, it just jams on full-auto sometimes. If it worked on semi-auto, should I still replace the bucking then? Thanks for the guide by the way.

Oh, and could you give me a link to the guide. I'm having a hard time trying to find it.
