KWA MP9 question

Jun 11, 2011 12:32am
Just picked it up today and am loving it(thanks brettro), however after shooting it for awhile on semi the bolt sometimes doesn't completely return and won't fire, I'm wondering if the nozzle is getting stuck or is it the guide spring not being strong enough? Google hasn't helped too much

Depends on the ammo. I have one as well and it happens with a few mags, going on Semi auto.

Somewhat common problem. The main spring, i think, should be of a heavier tension from factory. You can stretch it a bit, or make a spacer out of about 1/2" worth of a bic pen body. Thats the main thing with these. There are other things to look for as well.

I'll have to try that myself.

thanks andrew, the piece of the bic pen worked, running .25's ran 4 mag's in a row and no issues

GTK all is well. If I knew it did that I would have mentioned it and or fixed it. Glad to hear all is well. :wink:
