Step 2: The firing pin
on the second pic the grey rods are bent it not because of the gun it because they old and the little bit with the blue spacers is a thing for dampening it so it doesnt destroy itself when you fire it.
on the fireing pin under the black tape is an orange rod connecting the grey rod to the slide i didnt take it all apart because i couldnt get the black tape off so youll have to look at the pic carefully for that.
Step 4: Backrest
make or gather all the parts in the first pic
Step 5: Trigger
Step 7: Add final piecies
the last two pics are the rubber band positionings the first one is for small rubber bands and the last one is for large rubber bands simply thread it through the slot inbetween the two barrel sections. n your done
