    My G&G CM M4 Blowback Gearbox will not open up! the imitation bolt came off, but only because I forced it (bad idea, I know), but the black cover over the gold chamber containing the blowback recoil spring and spring guide will not budge. I have seen YouTube videos were the people effortlessly pop them off but mine just doesn't! It may have something to do with the fact that the wiring inside the gearbox is misplaced and the box itself is slightly open, but I can't get the wires back into the right place without opening the gearbox, and I can't open it! PLEASE HELP ME......

    Make sure all your screws are out. It looks like there are still some in it though.

    That blowback assembly on top looks like it's holding the top together. Try taking that off.

    Put the damned screws back in. The gearbox being open is causing the blowback assembly to be pressed on by the rails it slides on, keeping you from removing it.

    That's because the gearbox is partially open...

    Is it your first time with gearboxes?

    If you want help, please take a picture of all the parts you can find, and I can tell you if you are missing anything. Make sure to look for a small bent spring, as that is probably the easiest bit to lose.

    Make sure you do tons of research before going into tech work. I learned this the hard way, and I'm still learning. It takes practice, patience, and persistence when it comes to GB work.

    My gun is in 100+ pieces right now so I just put them all in a box and will take it to the field I'm going to sunday. The tech there can put it back together for me.

    You know, you can probably get it back together much easier than you think, it seems complicated but once you know what everything is it's pretty easy.

    I'll try again but probably fail miserably. I can probably get someone at my game to help me out if I need it. Thank's for trying to help me though.
