Jamoy Posted January 16, 2012 Share Posted January 16, 2012 Hey i recently baught a KWA mp9 and havent even skirmished it yet. Then suddenly it dosnt even fire! I mean when it fires it only has a velocity of maybe 240 fps which is not good. And sometimes the bolt and gas expansion chamber dosnt seem to seat properly. And on full auto it fires maybe 2 rounds then the entire magazine worth of gas is dumped in a massive woosh! I have disasembled the gun to give it a clean then relubed it with some silicon spray. No use! I have lost a small stupid pin that holds the trigger sear back like .4 mm further than it currently sits which should not be the deal as i have made a makeshift one and it made no difference. I was using .2g ASG Blasters with Abbey Brut Sniper gas (Which kwas should be able to withstand) What can the problem be? Cracked gas nozzle?

The nozzle was quite crap quality and barely a mm thick. Im going to write to KWA about this. Link to comment Share on other sites More sharing options...
REMSoft Posted January 16, 2012 Share Posted January 16, 2012 Have you considered that you are using a gas weapon in winter? Link to comment Share on other sites More sharing options...
Supporters Rock-climby-Dave Posted January 16, 2012 Supporters Share Posted January 16, 2012 It is loading the mag into the gun with the bolt forwards (uncocked). To load an MP9 and NOT break it: 1. pull bolt back and apply bolt lock 2. put mag in to click 3. press bolt release. 4. KIIIILLLLLLLLLLLL obviously, this is too late for you now, and it IS repair the gas nozzle jobby. Link to comment Share on other sites More sharing options...
