G&G M4 Lower receiver disassembly?
 

Hey all.
I tried using the search to find a thread with instructions but nothing came up.

Can anyone post a link to a guide for disassembling a G&G M4. I need to remove my Cansoft Clear receiver and install my metal one and can't seem to figure it out on my own.

How do I remove the cylinder that the butt-stock slides over?

Im a total noob, and have never done this before. All help is appreciated.
Noob-bashing is exepcted.

Hey....so here is the regular procedure for armalites that are not SRC.

Take the two body pins out (front and back)

Crack the body making sure you are not damaging the wires (front or rear wired)

If rear wired, the upper should be completely free of the lower. If front wired you may want a steady solid surface to rest it on so there is no stress on the wiring.

Remove the stock from the buffer tube if crane stock. Can be tricky and may require some force. Once the butt is removed from the stock, there will be a screw to remove the buffer tube cap. After the cap is removed, the screw will be exposed at the other end of the buffer tube. Remove this screw.

If full stock, simply remove the screw parallel to the cylinder.


Now that the Upper and the stock are completely removed, you may take the pistol grip off by removing the plate under the grip.

Remove the Black and Red leads from the motor terminals and remove the motor. (Be careful not to lose the spacer washer that is on top of the motor.)

Once the motor is removed, there should be two screws that hold the pistol grip to the gearbox. Remove them.

Now that the pistol grip, stock, and upper are completely removed, you can now take off the magazine release assembly.

After taking off the mag release, take the final, small body pin out. (Near the middle of the gearbox.)

Taking the gearbox out may be tricky. You may need to pursuade it by pulling the cylinder housing back and forward to wiggle it out.



Please, anyone, if I left something out or am wrong about something, please feel free to correct.

To complete with Stubby,

:rolleyes: can you tell who IS bored at work?


I am, I am!!!! :D

Just to add also, put your selector switch on semi, helps when trying to remove it from the body.

Thank you very much for the info.
The link to the video is very helpful.
Im going to put this off till tomorrow. Its for work. We sell AEGs and GBB Pistols and we just ordered the new Metal G&Gs which are just the old ones with an extra metal receiver. *SIGH*

Really disappointed that they didn't come pre-assembled.
Again, thanks guys.

Good point, can't remember if I did that or not. Best to be proactive though.

Putting the back body pin was a pain in the ass for me. Had to do a little bit of modifications to the body.

Click ON Maintenance.. Then click on the model...

Really? when i disassembled my G&G the back pin comes out with a little tap and when placing it back in the AEG, it goes in smoothly, no problems.

What do you mean by "modifications"?

You're doing it wrong.

I found it that with my plastic body, if I tighten the screws in the grip too much, it would distort the body slightly, thus giving me a hard time with the rear pin. (Using a MIAD grip)

If it's your case, loosen these screws, put the selector on auto (make sure you didn't forget the pin in the GB) and the rear pin should slide in with no effort.

The pin fits inside the entrance, and through the body (the side with the forward assist and dust cover), but on the side with the selector, it won't come out. The hole itself is too small for the pin. The exit hole has a indented small ring which stops the pin from exiting. So the modifications I had done to it was basically chiseling and filing.

I highlighted the metal stopping the pin from going in with yellow. It was a perfect circle too, so I don't think it was just a little bit of extra metal. Basically if the yellow wasn't there. My pin would fit in perfectly.

If you need to do modifications thats bad.. I can take mine apart with ease now. It was a little harsh the first time where it almost sounded like it was going to crack but it's fine..
