15. Before removing the action from the stock, you may wish to take off the folding bayonet. Place the blade between its two positions, and remove the pivot screw. Control the spring. The locking “handle” and spring are easily taken off the blade.
16. Remove the cross-screw and the top screw from the front end cap of the stock, and slide the end cap toward the front.
17. Tip the rear sight to its raised position for clearance. Lift the front of the handguard to clear the gas system base, and take off the handguard toward the front. Re-fold the rear sight to prevent its damage.
18. Remove the three vertical screws in the trigger plate. Note that all three have washers, take care that those are not lost. For the center screw, the magazine catch must be pushed away during removal.
19. Remove the action from the stock. The screw sleeves at each end will likely stay in the stock, but the center one will be released. Take care that it is not lost.
20. Restrain the hammer, pull the trigger, and ease the hammer over to fired position. Take the trigger group out of the stock.
21. Remove the hammer spring and its guide. The rear part of the guide will stay in the unit.
22. Drifting out the crosspin will release the hammer for removal. Note that all of the pins in the trigger group are likely to be staked in place, and should be taken out only for repair purposes.
23. Drifting out this crosspin will release the magazine catch and its spring. Control the spring. The lock-piece and its spring are mounted on the catch by full-riveted cross-pins, and these are not routinely removed.
24. This pin pivots and retains the trigger. If removal is necessary, the sear bar must be depressed, and the trigger is taken out to the rear and upward. Control the spring. The trigger/sear bar is full-riveted at the top of the trigger, and is not routinely removed.
25. The sear crosspin is heavily riveted, and should not be routinely removed. If this is done, control the sear spring.
26. This pin retains only the rear portion of the hammer spring guide.
27. The rear sight unit is removable by taking out the two screws on its underside that retain the retaining clips. These are slid away from the sight base for removal.
