So I decided to move my stock/ backup CM16 gearbox into a metal DD M4 body while my main motor undergoes some surgery. However, I discovered I can't remove it completely due to the buffer tube wiring (shown in picture), specifically a white plastic tube covering the red wire that won't fit past the metal piece that holds the screw. Additionally, the metal piece seems to either be stuck or welded into the buffer tube (I've tried banging it out already). Anyone know how I'd go about solving this?
