MP7 Takedown Guide (Major 56k Killer, over 50 pics)
« on: June 25, 2007, 04:45:51 PM »

Disclaimer: This is not my guide. I have taken this off of Arnies for all you people without accounts there. Any and all ownership of this guide and its pictures belongs to Arnies and staticzero, the guy who wrote this. I shall repeat, I DID NOT WRITE THIS!!!

We're going to turn this...


...into this. Note that it's not necessary to remove the flash hider and side rails for this, mine were simply removed already. You'll need to remove the sights if they're in the way of the top rail screws.


Start by removing the stock. Pull both catches up and slide the stock out and free. Take the front set off too


Next take the top rail off. The screw above the selector is a dummy, don't remove it. The longest screw goes in front; keep this in mind when you reinstall the rail later.


Pop the charging handle return spring off using a small tool and set it aside...


Remove the charging handle retaining screw next. You may also remove the charging handle at this time


Now remove the body pin screws


And then push out the body pins


The end cap will be free now. Remove it and set it aside


Here's the inside view at this point. You can see the back of the gearbox


The next step is to remove the serial number plate. It just slides out


You may then remove the gearbox retainer shim. The gearbox will slip down a bit after this is removed


Look above the gearbox and note the semi-auto cutoff lever actuator arm and its connection to the semi-auto cutoff lever. You'll need to get this back correctly when reassembling the gun or you will not be able to switch to auto


Now pull the gearbox out of the back. You'll need to disconnect the wires first of course; they need to be fed through the slot in the top as you remove the gearbox


When putting the gearbox back in you'll need to use a small tool to pull the wires back up


Here's the gearbox. It really is very small


The inner barrel assembly can now be removed. It'll just slide out


Here's the hop up unit as viewed from the left side


and the bottom


and the right


and the top


and the back


Now is a good time to remove the 'bolt'. Slide it back as far as you can


Press down on the part towards the top


Here's another view. Pressing this down will allow it to come free of the track inside


It can then be pulled out the back


Here are all the rear set components


Now it's time to take out the selector lever, trigger, and bolt release so the switch assembly can be removed. Start by pushing out the bolt catch spring pin. Don't lose it! Pull the lever off and set is aside as well


Now pull out the lever very carefully, pay attention to the spring's position


You can see the hooked part catches the post in the lever and the straight part fits into a notch in the hole


Now push out the trigger pin. Don't force it; it's designed to go one way. If it feels tough try pushing from the other side. You can see in this pic the side that should come out first has grooves in it


With the pin removed the trigger is free. I was worried that the trigger would be a nightmare to get in and out but it's fairly easy


Just pull it forward and out. Pay attention to the spring as you do this so you have an idea how to get it back. It's basically the reverse of removing it


Next knock out the selector lever spring pin and remove the selector lever. Set it aside in a safe place along with the lever parts


Here's the left side of the body with the bolt release, trigger, and selector components removed


And here's the right side


These are all the components that were just removed


Looking in the back, the switch assembly can be seen. Carefully remove it from the gun using tools to poke at it from the front if need be. It's held in position by rails and can be tricky to get back in place. Just take your time and poke at it through available holes. You'll get it


Here's the right side of the switch assembly


And the left


Another look. You can see the battery connector in the front


The fuse is rated at 10A if you were curious. The gearbox must not be very demanding


Here you can see where the barrel goes though the assembly


Here are all the major internal components


Here they are as they would be inside the gun when assembled as viewed from the left side


and the right


This is the connection between the semi-auto cutoff lever actuator arm and the actual semi-auto cutoff lever that was mentioned earlier


Close up on the left side of the switch assembly


And the here's the right side


This is the bottom; you can see some of the trigger mechanism


Here you can see some more of the trigger mechanism


This is what the selector mechanism looks like on safe


This is semi. It's a small difference


On auto the selector plate pushes against the cutoff lever actuator arm which disengages the cutoff lever in the gearbox


Here's a look deep inside the gutted body. There are still a few bits in there but there's no need to remove them


And now more shallow look


A view from the front


AGAIN, I REPEAT, THIS TAKEDOWN GUIDE IS NOT MINE!!! Do not give me any type of credit for this. This whole guide was taken off of ArniesAirsoft and was written by staticzero. I have nothing to do with the writing of this.

This is nice to know, but what is up with that gearbox? How can you fit all the parts in there?

^Magic.

But seriously, that is pretty cool......I am always astounded at how many parts there are in a gearbox.

Some people tell me that "TM is better than CA because it's the internals that count, and that the nice externals of CA don't make up for its poor internals compared to those of a TM." I disagree. Good externals are much more valuble than good internals. Just look at my girlfriend.

This is a nice guide. Going to have to remember to look at this if my MP7 ever breaks down.
