KWA M93RII Ns2 problem

[McCrea]

Hi,

here is the problem. When there is no gas in the mag, put it in the gun, I can cock the gun just fine.

But when there is gas in the mag, put it in the gun, then I can't cock the gun anymore, the hammer won't stay down. Also when there is not much gas left in the mag just shoot out the gas left in a long burst.

I've looked into it, and it seems like the firing pin (little piece that strike the mag valve) can't slide back beside the valve when there is gaz in the mag.

Is the firing pin too long? I've tried to lube, the pin and the mag, not working.

The gun is stock. almost new.

rack the slide before inserting the mag, see if that makes a difference

If I rack the slide before inserting the mag, everything fine, but I have to rack it again to load a bb.

[Thenooblord]

well if you rack it to chamber a round when the hammer was already cocked before the mag was inserted, does it work?

[McCrea]

Yes it works but its suppose to work when i rack the slide with mag inserted

All KSC and KWA guns come like that I've noticed (well system 7 anyways not to sure about pre-system7), The valve knocker or whatever it's called is on a hinge and moves up and down. From what your saying sounds like you have to cock it twice, it may be a pain in the ass but just have it pre-racked then stick the mag in again and rack it again.
