King Arms M4 GBB Help

[deRuijter]

Hi guys ive got a problem with my M4 GBB KA i disassembled my M4 just to see hows it going and to remove the buffer but now i cant close it because 1 pin doesnt go in well its the one above the trigger somekind of little Pin.

Could we have a picture?

PS: some pins need quite some force to go back in....

Or if it's the pin connecting the trigger sear, the trigger... make sure those 2 parts are properly aligned...

Yes i think the exit gets blocked by some kind of wire how can i remove the Trigger it should go back in there again.

I mean to take out the trigger and gearbox i think you call it

[Gunny_McSmith]

Gearbox? is you gun a GBB or an AEG?

[deRuijter]

Its a gbb but i dont know what the trigger part is called sorry for confusion.

[Gunny_McSmith]

o kk.... but could you take a picture of it please?

I really dont know what you mean by wire... :S

im going to assume he is referring to the auto sear. sits above and behind the trigger group, just above the selector switch. that "wire" thats blocking the pin is part of the auto sear spring. at the end of the spring it is bent inwards to act as a lock for the pin. you kinda just have to line up the pin with the hole and hit it with a mallet to push the pin through. there should be a slot cut out on the pin for that section of the spring to sit into.

this is a RS auto sear. the airsoft version should only have one cut out, on one side.

oooo if its the fullauto sear.... then they are hard to get in.... there's a guy that will show you how to isntall it in on Youtube...
