      18. The magazine floorplate latch is retained in the receiver by a vertical roll pin, and this pin need not be drifted completely out to free the latch and spring. Just drift it upward enough to clear the latch, and take out the latch and spring toward the front.

      19. A roll cross pin at the rear of the trigger group retains the safety plunger and spring. Restrain the spring at the top when drifting out the pin, and remove the spring and plunger upward. Remove the safety toward either side.

      20. Move the bolt so the operating handle is accessible in the ejection port, and insert a small screwdriver to lift the handle latch outward. Move the handle forward, out of its recess in the bolt.

      21. Move the operating handle to the wider opening in the bolt cover, and remove the handle toward the right. The latch and spring are retained in the handle by a very small cross pin, and are easily removed. In normal takedown, they are best left in place.

      22. After the handle is removed, move the bolt assembly about half-way to the rear, bring it downward from the roof of the receiver, and take it out toward the rear.

      23. Move the bolt cover to the rear of the bolt, and push upward on the right lower edge, tipping it over toward the left, and snapping its guide flange out of the groove on the bolt.

      24. Drift out the cross pin in the rear tail of the bolt, and take out the firing pin and its return spring toward the rear. The ends of the cross pin are contoured with the bolt tail, and care should be taken not to deform the ends.

      26. Move the bolt forward out of the bolt sleeve.

      27. Drifting out the vertical pin on the left side of the bolt carrier will allow removal of the timing latch toward the left. The pin must be removed upward.

      28. The ejector is retained at the front of the bolt by a vertical pin. Caution:Restrain the ejector, and ease it out after the removal of the pin, as the ejector spring is compressed.

      29. Use a small screwdriver to push the extractor spring up out of its groove, and remove the spring toward the rear.

      30. After the spring is removed, the extractor can be moved downward, into the bolt face recess, and is taken out toward the front.

      Reassembly Tips:

      1. When replacing the bolt in the bolt carrier, be sure the flat between the bolt lugs is on top, and the extractor and ejector at upper left and lower right (front view).

      2. When replacing the cam pin in the bolt and sleeve, the small hole at the center of the cam pin must be oriented properly for passage of the firing pin.

      3. When replacing the bolt in the receiver, the blot must be at its forward position in the sleeve, to allow the timing latch to be retracted.

      4. When replacing the gas piston, note that there is a guide pin at the lower rear of the gas cylinder, and the piston must be oriented so its rear groove will mate with the pin.
