As per title, I am having issue with the fire select. The small “knob” on the inside of the receiver, the other side of the switch, isn’t catching on the plate, and holding it forward. So I am constantly on full auto.
I have pulled the box apart and checked to see if it’s all sitting right, which it is.
It just seems as though there is so much pressure, the thin plate is bending upwards and the small “knob” is sliding underneath it…
