Marco Posted May 13, 2019 Share Posted May 13, 2019 The gun is cycling but not all BBs are coming out.Also If you look at the video the magazine is empty and its not locking In empty position.I have changed the recoil spring guide and springsI have changed the nozzle but the problem still persistsThe trigger bar and spring seem ok, so the chassis/hammer and slide release bar and spring. I will try changing the loading nozzle spring before checking again the hammer part (I do have a whole hammer and chassis kit from JKW, if compatible I could try to swap it)Any suggestions?

Mostly Retired Moderators L3wisD Posted May 13, 2019 Mostly Retired Moderators Share Posted May 13, 2019 Have you put a stronger recoil spring in it? Tried it with the old one back in? Link to comment Share on other sites More sharing options...

Guest Posted May 16, 2019 Share Posted May 16, 2019 Have you tried multiple mags? Same issue with each one? I can’t see the video, but often poor cycling is due to worn components or mid-matched springs Link to comment Share on other sites More sharing options...
Marco Posted May 16, 2019 Author Share Posted May 16, 2019 Thanks. Yes same issue with all the mags. I have now changed the nozzle spring too and the issue still persists. i have also added a new recoil guide and springs (guarder) I'll move next to the trigger bar and spring, then the hammer set.

Guest Posted May 16, 2019 Share Posted May 16, 2019 In my experience, matching the hammer spring and recoil spring will solve most cycling issues, it doh ds like you don’t have the right hammer spring then Link to comment Share on other sites More sharing options...
Marco Posted May 16, 2019 Author Share Posted May 16, 2019 Hammer spring is still the original one. I'll try swapping it with the guarder one. Link to comment Share on other sites More sharing options...

Absolute must match your recoil and hammer spring rates, did you buy them together as a matched pair? Link to comment Share on other sites More sharing options...
Marco Posted May 16, 2019 Author Share Posted May 16, 2019 I only changed the recoil spring because of the issue. Apart from the nozzle the gun was stock. Yes the springs are all a guarder set. Link to comment Share on other sites More sharing options...
Guest Posted May 16, 2019 Share Posted May 16, 2019 I can see the video now. I don’t think your hammer is hitting the release valve in the mag properly. When/how did the issue start? Is the knocker lock operating correctly can you see? Link to comment Share on other sites More sharing options...
Marco Posted May 17, 2019 Author Share Posted May 17, 2019 It seems so, btw i have changed the knocker lock spring too, the previous one one a bit bent. I'll do more experiments this week end, thanks Link to comment Share on other sites More sharing options...

So I changed the hammer spring but it didn't fix the issue, I swapped the whole hammer assembly with a kjw one but the problem persisted. I'll start check the slide assembly now. Anyone can suggest a technician that service GBB guns? Link to comment Share on other sites More sharing options...
