Okay so I've had my kmp9r for like 2 months, gun kept double feeding, like when loaded up with fresh mag, I use it on semi and first shot is fired then it stops working. When I take the mag out and cock my gun back, I see a bb in the chamber, I shake it and it falls out. Tried everything and it keeps doing this. I even took apart the gun and found a bb lodged in between the piston, I managed to take it out and still no help. Everything is lubed with silicon oil. KWA staff, any idea's as to what's wrong? Should I drop it off to get it fixed? I live pretty close to your headquarters. Any help would be great! Thanks!

Hold on. EVERYTHING is lubed with silicone oil? That might be one of your problems if the hop up bucking has silicone oil in it. KWA hop up buckings are designed to be used dry. Silicone oil will lead to swelling of the hop bucking, which might be the cause of your feeding problems.

Also, i think you might have a problem with your recoil spring if it stops working after one shot. The bolt might not be returning forward all the way. In any case you'll need to at least get the bucking replaced if its swollen so its time to hit up the help desk.

hmmm.... any possibility of a video?

Starting to narrow down the possible issues. Perhaps it is a cylinder problem. Did you try pushing the bolt forward yet like i mentioned earlier?
