Removing a M4-S stock?
 

heh, trying to take apart this M4-S that my boss wants upgraded, but I have never taken apart a M4 before.
I know how to work inside the gearbox, but I cant figure out how to get it out of the reciever, and I really dont fnd the parts diagram too helpfull at all.

So, if someone can tell me how to get the gearbox out of the lower reciever of an M4-S that would be appreciated. As far as I can tell, the stock still needs to some off, and the safety is still attached, so taking it from there shouldnt be too hard.

Thanks.

Bump?
