Disassembly:

1. Pull the trigger to drop the striker to fired position, and remove the magazine. Loosen the stock mounting bolt and pull it out until it stops.

2. Move the action straight up out of the stock.

3. The trigger guard unit and the buttplate are each retained on the stock by two wood screws. The stock mounting bolt can be removed by continuing to turn it counterclockwise.

4. Remove the small Phillips-type retaining screw and take off the case deflector.

5. Back out or remove the small Phillips-type screw on the underside of the receiver at the rear.

6. Unscrew and remove the receiver end cap. Caution:Springs are under tension, so control the cap.

7. Easing the spring tension, remove the end cap, striker spring, recoil spring and their attendant sleeves and guides, toward the rear. If these elements are not being taken out for repair or replacement, it would be well to keep them in original order for reinstallation.

8. Point the barrel upward and retract the bolt handle fully to the rear. While exerting slight outward pressure on the bolt handle, push the striker (firing pin) forward until its exit cut aligns with the bolt handle. The bolt handle can then be removed toward the right.

9. Pull the trigger to free the bolt and remove the bolt assembly toward the rear.

10. The striker (firing pin) is easily removed from the top of the bolt.

11. Insert a small tool between the extractor and its plunger, and depress the plunger toward the rear. Lift out the extractor. Caution: Control the plunger and the compressed spring, and ease them out.

12. The bolt handle has a knurled sleeve that is pushed in to lock the bolt open. This can be removed by pushing it toward the inner tip of the handle shaft. Caution: The tension ball bearing and spring will be released, so control them. The ball is on the same side of the shaft as the striker recess.

13. Remove the small Phillips-type screw that retains the safety catch on the right side of the trigger group.

14. Hold a fingertip over the rectangular opening in the safety, and move the safety toward the rear until the detent ball jumps out against the fingertip.

15. Use a magnet or a magnetized tool to remove the detent ball, and take out the spring.

16. Remove the safety catch toward the rear.

17. Drift out the trigger stop cross pin toward the right.

18. Drift out the trigger cross pin toward the right.

19. Move the trigger assembly downward and toward the rear for removal.

20. The sear trip, or “rebound lever,” to use the factory term, is pivoted and retained on the trigger by a cross pin. In normal takedown, this is best left in place. If it is removed, the small ball bearing and spring that power the trip will be released. Caution: Control these parts.

21. Remove the trigger spring and plunger from inside the housing at the rear.

22. Remove the rear housing retaining screw, located inside the housing, just forward of the trigger spring. Take care that the washer isn’t lost.

23. Remove the large retaining screw at the front of the housing, along with its lock washer.

24. Remove the trigger group housing from the action.

25. Because the trigger housing is made of alloy, and the parts are steel, further disassembly should be done only if repairs are necessary. We will show the sequence here, without actual removal of the pins and parts. To remove the magazine catch, first drift out the stop pin.

26. Drift out the magazine catch pivot pin toward the right. Caution: Insert a shop cloth in the magazine well to catch the released spring.

27. Drift out the sear stop pin. Restrain the sear as the drift is removed and ease it upward.

28. Drift out the sear spring retaining pin, and remove the sear spring downward.

29. Drift out the sear pivot pin and remove the sear upward. Again, note that while we have shown the sequence here, the parts are still in place.

30. The stock mounting stud can be drifted out of its dovetail if necessary. However, note that it is factory-staked in place. In normal takedown, it is not removed.

31. The front sight is retained by a small Phillips-type screw. The rear sight is a dovetail mount, and it is drifted out toward the right.

32. The barrel is retained by a large cross pin. In normal takedown, the barrel is not removed.
