2. Slide the forend forward until it stops, and swing the cocking lever lifter out of its recess in the front underside of the receiver.
3. Operate the barrel latch, tip the barrels downward, then remove them toward the rear and upward.
4. Remove the cross screw on the left side near the lower edge of the forend.
5. Slide the forend wood forward until it clears the mechanism, and remove the wood downward.
6. Drive out the large cross pin in the forend base, tho pivot for the forend latch.
7. Remove the latch lever downward. Drifting out the cross pin at the front of the latch lever will allow removal of the lever release and its spring.
8. Slide the forend base mechanism forward until it stops, then remove it downward.
9. Pushing out the small cross pin near the large retaining pin will allow removal of the cocking lever lifter downward.
10. Trip the ejector hammer sears by inserting a tool in the slots in the rear face of the forend base, to allow the ejector hammers to snap toward the rear, relieving part of their spring tension.
11. Grip the tip of the ejector hammer spring plunger (guide) with sharp-nosed pliers, and tilt the pliers to lever the nose of the guide out of its depression on the back of the hammer. Caution: The spring is still under some tension, so control it and ease it out. Remove the spring and guide toward the rear, and repeat the operation on the other spring and guide.
12. Drifting out the large cross pin at the rear of the forend base will release the ejector hammers for removal toward the front.
13. The ejector hammer sears are retained on each side by small pins in the upper wings of the forend base, and these pins are contoured on the out-side to match the curve of the base. These are difficult to locate, and if possible should be left in place. If removal is necessary for repair, each pin must be driven out inward to release the sears and their springs.
14. Move the ejectors back until the hole in the side of each one aligns with the retaining screw. Back out the screws, and remove the ejectors toward the rear.
15. After the ejectors are removed, the ejector extensions can be slid out toward the rear. It is not necessary to remove the stop screws.
16. Remove the two screws in the rear tail of the trigger guard. The guard is not removed at this time.
17. Remove the buttplate, and use a B-Square slock tool or a long-shanked screwdriver to remove the stock mounting bolt, lock washer, and washer toward the rear. Take off the buttstock toward the rear.
18. Turn the trigger guard straight out to either side, and remove it downward.
19. With the hammers in cocked position, it is possible to remove both firing pins without further disassembly. The upper firing pin is retained by a cross pin that is driven out toward the right, and the firing pin is removed toward the rear.
20. The cross pin that retains the lower firing pin is drifted out in the opposite direction, toward the left, and the lower firing pin and its return spring are taken out toward the rear. The upper firing pin has no spring.
21. Operate the trigger and intertia block to trip both sears, dropping the hammers to the fired position. Insert a tool behind each hammer spring guide, and lever them outward, disengaging the nose of the guide from the recess in the back of each hammer. Caution: These strong springs are under tension, so control them during removal.
22. Drift out the trigger cross pin.
23. Move the trigger forward and downward, detaching the inertia block from the underlug of the safety button. Slide the trigger connector downward, detaching it from the inertia block. Restrain the inertia block spring and plunger, as these parts will be released as the connector is moved downward. The trigger is removed downward, and the inertia block toward the side. Drifting out the small cross pin in the trigger will allow removal of the trigger plunger and its spring toward the rear.
24. Use a tool to lift the front tab of the safety spring out of its recess, and rotate the spring straight out to either side. The spring is removed downward, and the safety button and small spacer block upward.
