Disassembly:

1. Remove the magazine. Hold the trigger to the rear, open the bolt, and remove the bolt toward the rear.

2. Remove the front stock mounting bolt.

3. Remove the rear stock mounting bolt, located between the trigger guard and magazine well.

4. Remove the action from the stock.

5. The stock buttplate and the trigger guard unit are retained on the stock by two wood screws.

6. Push out the trigger pin toward either side. Restrain the trigger, as the spring is under tension.

7. Ease the trigger downward. It is not taken off at this time, as it is still retained by its sear-contact cross pin. That cross pin, and the one that pivots and retains the spring guide, are riveted in place, and routine removal is not advisable. The trigger spring and the adjustment lock-washer can be removed from the guide at this point. Take care that the small washer isn’t lost.

8. Restrain the sear, and push out the sear cross pin. Caution: The sear spring is powerful, and there is a small ball bearing between the spring and the receiver. Control it and ease it out. Considering the reassembly difficulty, this system is probably best left in place unless removal is necessary for repair or refinishing.

9. Remove the sear and trigger assembly downward. After removal, the parts are easily separated.

10. The magazine catch and its spring are pivoted and retained by a cross pin. Caution: Control the catch and its spring as the pin is drifted out. The magazine housing is retained on the receiver by two screws, at front and rear.

11. The front sight hood can be sprung outward slightly and slid forward out of its tracks. Backing out the front sight elevation adjustment screw will allow the sight blade to be slid down and forward for removal.

12. The rear sight is retained Mauser-style. Push down at the front and slide it toward the rear for removal. There is no cross pin.

13. To remove the twin extractors, insert a tool and pry the end of the saddle-spring outward, just enough to clear its retaining shelf. As the spring is removed, control it. The extractors are then lifted out of their recesses.

14. With the bolt held securely, use a tool to push the combined striker and firing pin toward the rear, and turn the bolt handle, allowing the striker to move forward to fired position.

15. Grip the front part of the bolt in a padded vise, and use a tool to depress the safety retainer until the safety can be lifted out. Caution: Control the retainer.

16. Easing the spring tension, remove the safety and the retaining plunger.

17. Remove the striker assembly toward the rear. The spring is easily removed from inside the striker.

18. Remove the bolt handle toward the rear.
