I guess you know that the barrel only comes off when the bolt is closed rather than open....
I stole this from another website for a complete dissasembly:
Remove the barrel and forearm.
Slide the bolt forward while holding on to the operating handle, dont let it fly forward or you will damage the reciever.
Push the 2 pins out of the side of the reciever and drop out the trigger group.
Move the operating handle so it lines up with the groove underneat it and pull the handle out.
Slide the bolt and slide bars out, make a note on how everything ia arranged.
Remove the butt pad and the nut that holds the stock on and remove.
Remove the pin that holds the recoil spring and remove the spring, careful cause its under pressure.
Clean and lube every thing, dont forget the inside of the reciever. I could not get the magazine apart so I just flushed it out the best I could.
Assemble in reverse order.
