TM m4, how to remove mechbox.
 

quick question for m4a1 by TM, how do i remove the mechbox, i need to move the wire from the back the recivers to the front like a standard m4a1, its set up like a SR 16 right now.

1-pull the stock release pin all the way to the bottom, pull stock off
2-unscrew the tail cap
3-remove buffer tube via the phillips screw in the buffer tube
4-unscrew the mototr plate ( under the grip)
5-remove motor, don't lose the little round plate.
6-remove front grips
7-unclip the two wires off the fuse plate
8 unpin the receiver
9-remove upper from lower
10-unscrew the pistol grip
11-unscrew the mag release
12-unscrew the feed tube
13-unscrew the little wire holder in front of the feed tube
14-remove cross pin
15-wiggle the mechbox out of the lower, a little prying force will be needed

that should be it

thnx vondnik :cheers:

Hammer.... j/k

im finding this alot harder than i thought.

Welcome to the club. Ain't easy at first until you get it, then it'll stick with you. What parts of Vondnik's list did you miss?

well i unscrewed the bottom of the grip, then i saw two wires clipped to this thing, and this little metal round bit fell out, put it aside, then i was lost. : )

This may help you.

gawd i hate working on armalites

pull the wires off, remove motor, take 2 screw out of the grip there.

To wire it to the front, your gonna need to take the mechbox apart too and rewire it so the wires come out the front, you cant just put them from the back to the front, gonna need to rewire it.

Just be warned that opening the mechbox is one thing, putting it back together is entirely another. You may wish to seek the services of a trained gunsmith to help you, and ask him if its ok to watch him work, its really helps to see someone proficient go through it once.

That piece that fell out is the motor plate that fits in the bottom of the hand guard cap. It allows the grub screw on the bottom of the cap to push the motor into alignment with the gears just right. You need this piece, or a similar replacement or you will ruin the teeth on your motor gear, if it even fires at all. Vondnik did warn of this in his list ;0)

Sometimes when I lose small pieces, I sweep (or vacuum if you must) and go through the dust pan until I find it.
