Okay the Parts that are metal are: Barrel, Front Iron sight, The Clips for a Sling, my Mags are metal, the rail system, Iron Sight the bullet ejection flap, the but stock latch, the thing the but stock attaches to (its a collapsible stock), the firing mode/safty switch, the screws that hold on the iron sight and all the sight adjusters the the trigger, and then 99% of the internals are all metal, (the only things that's not is the little gear that controls the Hop up system), the button on the side of the gun that I am forgetting the name of that you press to eject a round if it gets jammed, and the bolts that hold the stock and a few other ones.
Plastic parts: the top and bottom mounts of forward grip, and the lower receiver and the actually but stock itself
