Disassembly:

1. The takedown latch is located on the underside of the forend, at its rear edge. Push the latch forward into its recess in the forend.

2. Retract the bolt slightly, and turn the barrel assembly clockwise (rear view) until it stops. Then, remove the barrel assembly toward the front.

3. Remove the screw on the underside of the forend, and take off the forend downward.

4. Slide the takedown latch forward out of its base at the rear of the barrel. Caution: Two plunger-and-spring assemblies will be released, and must be restrained to prevent loss. The first will be the positioning plunger and spring at the rear of the latch, and the second will be the wedge-shaped plunger under the latch which bears on the barrel adjustment nut serrations. Ease both of these out, and take care that these small parts aren’t lost.

5. Remove the takedown latch base ring toward the rear. Unscrew the knurled barrel adjustment nut and remove it toward the rear.

6. Insert a finger through the trigger guard, place the thumb on the bolt handle, and retract the bolt to the rear while exerting forward pressure on the guard. The trigger group and bolt assembly can now be moved forward together and removed downward.

7. Pull the trigger to release the striker into the bolt, then move the front of the bolt upward out of the guard unit and ease it off forward. Caution: Both the bolt spring and the striker spring are under some tension, so take care that they don’t get away. Remove the springs and their guides from the rear of the bolt.

8. Remove the striker from the rear of the bolt.

9. Drifting out the cross pin at the lower front of the bolt will release the extractor retainer and allow removal of the extractor and its spring downward.

10. To remove the inner magazine tube, pull it out until it stops, then turn it 180 degrees to clear its side steps from the detents in the outer tube and take it out toward the rear.

11. Drifting out the locking cross pin at the head of the inner magazine tube will allow removal of the handle piece, spring, feed cable, and follower.

12. Use a very wide screwdriver or a special shop made tool to remove the nut at the rear of the buttstock, and its lock washer, and take off the stock toward the rear. The outer magazine tube can now be unscrewed from the rear of the receiver. Caution: Avoid gripping the tube too tightly and deforming it.

13. Swing the cartridge stop toward the inside wall of the receiver to clear its inner arm and lift it out of its pivot-hole in the roof of the receiver. It should be noted that on older guns that have seen a lot of use, the cartridge stop may fall out when the bolt and trigger assembly are removed, so be sure it isn’t missed and lost.

14. Removal of the cartridge guide spring in the top front of the receiver will release the cartridge guide to be taken out toward the front. To remove the spring, use a small tool to pry its rear loop from beneath its flange in the receiver.

15. Drifting out the small cross pin (upper arrow) at the top of the vertical trigger group extension will release the sear spring and plunger for removal upward. Drifting out the sear pivot pin (lower arrow) will allow the sear to be taken out toward the front. The trigger and disconnector pivot on the same pin, are removed as a unit, along with the disconnector spring. The disconnector can be separated from the trigger by drifting out the short pin that mounts it in the trigger. To remove the safety, use a small screwdriver to depress the plunger and spring inside, at the center, under the safety, and move the safety out toward the right. Caution: Control the compressed spring and plunger and ease them out.
