""Procedure:

      (It is obviously illegal to modify an AK-47 in this way. Don't!)

      Remove the magazine from the receiver. Remove the Receiver Cover by
      holding in the square button that sticks out the back of the cover.
      Slide the Return Spring and the Bolt-Carrier with Piston assembly out
      of the rifle.

      Using the twist-tie, tie the second Sear back to the pin that runs
      through the receiver of the rifle.

      Now reassemble the weapon. Slide the Piston and Bolt-Carrier back
      into the rifle. Slide the Return Spring back into the Bolt-Carrier
      and slide the other end of it into its guide slot. Push the "button"
      end of the Return Spring while settling the Receiver Cover back into
      place."


And the rifle will jam after the first shit. You obviously dont know anything about guns and the ATF rules of manufacture.
