How do you remove the grip for a JG M4A1? extremely urgent. will choose best answer?

Question

I need help!! Alot of it.

Well today i was just a little curious so i tried to take my JG M4 apart. I started with the upper reciever removing the pin, But when it came to the lower reciever, the pin wouldnt come out as easily as the upper, and i didnt want to force it. So i just said the heck with it, theres no need for me to take it apart if theres nothing wrong with it. Then I decided to check out the motor. Here is where the problem is.

I unscrewd the bottom of the grip, and i could see the motor. I tried to pull it out, but it didnt come out easy, and i didnt want to damage the gun, so i just left it in. I screwd the bottom of the grip back on, and then i decided to go shoot off a few rounds to see if anything at all was damaged while i TRIED to take the gun apart.

Everything seemed fine for a few rounds, but when i fired the gun on semi, the trigger locked up, i switched it back on auto then the bbs flew out, After that semi worked fine for a few rounds, then the trigger locked again. I did the same thing as before, then semi worked. I figured i needed to charge my gun, so i dry fired a few rounds to clear the chamber, then a tiny s***w fell from the grip. It was the tiny s***w in the middle of the other two big screws at the bottom of the grip.

I figured i needed to tighten the screws a little more so i took the bottom of the grip off, there i saw the motor, and then this little tiny silver washer, idk what its called, but it is small, silver, and belongs somewhere near the motor. Now heres the problem, the small washer thing somehow fell up into the grip, now i cant get it out. I can see it but it wont come out. I basically need to take off the entire handle or grip of the rifle and flush the washer out. But again I dont know how to do this. Can some one please tell me how to remove the entire grip of the rifle so i can flush this piece out!!! also if anyone knows exactly where i can place the washer in the grip when i get it out, i think the washer is suppose to be touching the little s***w that fell out but im not sure. also can some one tell me if i really messed up my gun? I dont think its a serious problem but i just want to make sure.PLEASE HELP ME THIS IS EXTREMELY URGENT, I HAVE A BIG AIRSOFT GAME COMING UP THIS WEEK I NEED MY GUN IN TIP TOP SHAPE!!!!

I promise I will choose best answer.

PLEASE HELP

Thank you

Answer 1

A) Relax.

B) unplug both wires from the motor.

C) holding the gun by the grip in your right hand, smack the grip down into your left palm. The motor should begin to slide out. Sometimes there's a piece of foam wrapped around it. when you can get ahold of it, pull it out.

D)recover the small silver disc.

E)slide the motor back in.

F)Plug both wires back up.

G)Take small silver thing, (actually a bearing surface), and put a small drop of something sticky, (syrup, thick oil, wax) a TINY drop, one one side of it.

H)place silver thing in indentation in center of inside of grip cap so that the sticky substance will make it stay in the indentation..

I) Again, holding gun by grip upright, place grip cap in place and push up into grip(hopefully keeping silver thing in place).

J)replace all screws.

The misfires were caused by silver thing shorting against motor contacts. It is a bearing surface between the motor shaft and the grip cap. The gun ought to work fine now.
