Anyone have any problems with the KWA MP9?

So I've had my mp9 for a while now, but for some reason it's started to act up and jam on me. It almost looks like the bolt doesn't fully cycle back and will leave a gap. Although the cylinder looks like its resetted its just the bolt thats not cycled. ANyone got any advice?

This usually happens when a BB gets inside the gun and blocks the movement of the loading nozzle. It's unfortunately a common problem with this gun.

Remove the upper, and see if a BB or something else falls out.

I tried that and nothing came out. I also tried making the disconnector spring looser which did help close the gap a bit but it still has problems. Maybe the actual recoil spring isn't strong enough?

There are two long but smaller diameter springs that run along the inside edge of the nozzle to the body (I can't remember their function) but they do at times get completely destroyed and this could be the cause of your problem

Look at the manual and the exploded parts diagram. This will give you a better understanding of what could be going wrong.

Bring it into Blackblitz and we can take a quick look at it. Could be something simple, could need to be submitted for tech work.
