Ever since Classic Army released the first model of their M15 line, just about everyone and their grandma has bought one. They have massivly improved over the years, and are now one of the top AEG manufacturers to date. With all these guns being purchased, also comes many people wanting to upgrade them. And where do they go? Airsoftforum.com. I have read countless posts on how to disassemble to M15A4 guns, so I thought I would make one final post to make life easier for everyone. Here it goes.





First, to make life easier, remove the carry hande. Then, remove the following Allen screw and the body pin that is near the foregrips, as shown.



Once the pin is removed, slowly start to seperate the recievers. This is done by pulling the charging handle back just a bit, and pulling the recievers apart. There is one point where the charging handle will get stuck on a part of the gearbox, just pull it back a little more and it should be able to get over it. MAKE SURE YOU don't PULL BACK TO FAR, or you will stretch out the spring. Once the recievers are apart, you should see this:





Next, remove the top screw in the butt stock. It is a long, flathead screw.



Once its all the way out, pull off the stock slowly, and disconnect the mini tamaya clip and remove the stock ring, which just slides right off.



Next, remove the tiny allen screw in the mag release button. Take off the button, screw, and spring. At the same time, the lever will fall out the other side. Just keep them all together so you don't lose the pieces. You should see something like this:





Next, remove this allen screw and punch out the pin it was connected to.



Now you will need to remove the two phillips head screws on the bottom of the pistol grip. Do not mess with the flat head screw in the middle, that adjusts the motor height.



Once the screws are removed, remove the motor plate and you will see the motor inside.



Disconnect the wires by simply pulling them off the connectors, and then remove the motor.



Once the motors out, look inside the pistol grip and you will see two phillips screws. Take those out, and remove the pistol grip. Watch so that the wires do not get caught on the holes. Your rifle should now look like this:





Now comes the harder part. You will have to punch out the pin located right above the trigger, next to the SAFE on the selector switch. I found that the allen wrench you used to remove the two main body pins works great as a punch, use that and a hammer and hit out the pin. It may, and probably will be very stiff to get out, but it will come out. I sprayed some silicon lube on it after I had it out and it got a little easier to put in and out.

Finally, the gearbox should be free, but its not quite out yet. You will have to work it to get it out. Put the selector switch to Semi, and push in the trigger. Then work it up and out of the box. It may seem to get stuck on the top by where the stock was, but it will go past there with a push. Just keep working it and it will come out. Heres a pic for reference:









Also, one more thing to note. On the reassembly, putting the motor in is different then normal, and some people have issues here. The wires go through each hole as you will see when you take it out, but then they both need to feed up to the BACK of the grip, before inserting the motor. The red wire has to "curve up and around". Here is a pic of how it should look when you insert the motor:



Make sure once you have the motor in and you think its right, push it down a little bit with your thumb. It should move back up from the spring on the motor shaft. If it goes down and sticks down, it is in wrong and you will need to remove it and try again.


Thats it, post here any questions. Thanks.
