So my kjw m4 won't fire in full auto. I took out the trigger group out and seen this part was broken off
It came off of here
But its suppose to look likethis
.
I looked at the blown up diagram, but I can't tell which part it is. I think it's part 38, but can't confirm!!! Its the area where is the hammer pin goes threw the body. Any help would be greatly appreciated!!! Thanks.
