Disassemble PS90 Stock - FN FiveseveN Forum:

Its VERY easy. Pull the mag, pull the upper receiver, pull the bolt out next, pull the rear buttpad off, then pull the trigger pack out.

Now unscrew the two halves of the body.
Pull out everything else!

Thats it!

My gun stayed together after the two halves were seperated. So you can see where everything goes. The only parts to be careful, of are the 2 tiny springs under the safety/fire switch. It has the typical springs that will fly out into your shag carpet (no matter where you are in the room). The springs have tiny "click" wedges on either end. This is the only thing you have to watch for.

Everything else is easy! The mag release is one piece with a fat spring behind it (it will also be the last thing you install). You will just slide it backwards into place after reassembly, untill it snaps in.

The ejection door cover in the "ejection port" is mostly one piece, and stays together well. It also reassembles EASY, depress the two spring sides and slide it up the port. It snaps into place. You dont even need to worry about re-setting the spring. it resets itself when you re-install the cover. Thats about it for pieces.

The trigger is attached to a bar. The dis-assembly is almost self explanitory.
I took the nuts out of the stock as well, just because.

The only "difficult" part is re-installing the safety/fire switch. You have to depress the two springs together with the "wedge" pieces on them, and slide them under the switch. The hard part comes from the "wedge" pieces rotating around while trying to stick them under there.

Dont be afraid, my seven year old re-assembled most of mine, with me verbialy guiding her.
