slight GBB m4 problem

[Infa]

Hello guys, im having a little problem and i can't justify what it actually is. I have a GBB m4 and the problem lies somewhere in mags or nozzle (i think). When i enter the mag, charge the rifle the first shot is perfect, however when i try to take the next shot it just spreads the gas everywhere.

Cheers

but wondering... Mags used to work previously. I just recently put npas inside the nozzle... could that be the problem ?

Re: slight GBB m4 problem

Okay cool, nah that shouldn't be the problem. It sounds like the spring on the nozzle has become unattached, if it's not that fiddle with the naps settings

Re: slight GBB m4 problem

my m4 used to have ALOT of probs but does it cycle or just completely vent on first shot because it could be something in you buffer tube blocking the full cycle or look as john said at your nozzle spring ether that or your npas is set so it doesnt cycle properly i think its a cyclic problem but i may be wrong? one way to tell fire then charge it and fire again and see if it vents?

Re: slight GBB m4 problem

Ok guys i have fiddled with it, it seemd like the bolt was getting stuck due to different buffer tube ( but already solved the problem just had to adjust the buffer tube) but now...
On Semi Auto it Fires Brilliant, On Full auto its different story... pours gas everywhere and i have no idea why it does that since it works nice on semi auto. Any idea??
