So, as the topic title says, I'm having some major issues here.

Every shot (sometimes it works for a few shots) it will load 2-3 BBs out of the mag, which will get jammed in the chamber area and require me to either shake or pick them out, only to happen again the next shot.

Also, when the mag is empty, it continues to dry fire without catching on the mag follower. I tried a brand spanking new mag and had the same issues.

The thing on the blow-back chamber that pushes the BBs up the ramp appears intact.


Thanks guys. I really hope I can get his solved. I do not have the box or manual or anything like that, so I can't call on the warranty. I'd like to get this fixed as soon as possible so I can get out and play/spray.

Here's a look at the chamber.

It's a bit rough, but would that cause this?

Anyone got any ideas?

My blowback chamber is marked MK11. New or old version?

edit: Ok guys, I took it completely apart, cleaned everything up and re-oiled everything. It's no longer jamming (well, rarely), but it continues to dry fire.

Any idea what could be causing the dry firing?

Also, a new issue I noticed. Even on lowest hopup setting, the BBs have too much backspin. Any suggestions on that?

I'm mostly worried about this dry firing....

Airsoft Canada seems to think my cylinder is screwed. I tend to agree with their conclusion.

...yay spending more money.

I had the exact same problem as you did before I sent my M11A1 NS2 into KWA. (My KWA M11A1 NS2 came from the very first batch.) Your cylinder's loading ramp has been worn down too much, so now it isn't loading bb's properly into your chamber. So, Airsoft Cananda is right, replace your cylinder and it'll be firing like new again.

FYI, After the first batch of M11A1 NS2's, KWA quickly replaced the cylinders with a redesigned nozzle/loading ramp. So, the new cylinder you install should last you a while, even though the previous one took me several thousand rounds to make it fail.

replace the hopup bucking too.

A fresh hopup bucking is always a good thing.  Like fresh undies :D
