Note: Make certain to follow steps 24 through 29 in the order they are given. Do not attempt remove the hand guard without removing the rear sight as you will most probably damage the hand guard. A "shortcut" is not recommended and could REALLY cause trouble. Many people try to pry the HG over the sight. Even with the slide-off method displayed the hand guard may still crack due to the spring clips.

Note: We purposely do not cover the disassembly and reassembly of the rear sight assembly because it is 1) not necessary 2) very difficult 3) and most likely if you successfully disassemble the rear sight you will not be as successful in reassembling the rear sight.
28) Unscrew the rear sight screw.
29) Remove the rear sight screw.
30) Unscrew the forward rear sight screw.
31) Remove the forward rear sight screw.
32) Remove the rear sight.

Not pictured: Removal of the front sight blade is performed by drifting out the retaining pin from the left towards right and insertion of the pin is the opposite from right to left. Any pins, such as that for the front sight blade, are driven in from the right, so should be removed from the left.
34) With the magazine gate closed, lift the lug so it is out of its seat.  Be careful not to damage the thin blade on the hinge pin. They can easily be bent or broken if the pin is difficult to rotate. It is best in this case to rotate the pin by lifting the lug at the front of the thin blade.
35) While holding the gate firmly closed tap the hinge bar out of the magazine. Make certain not to push forward on the thin, flat lug.
36) Remove the hinge bar.

44) Using a drift push the pin out of the carrier and follower.
45) Separate the carrier and follower.
46) Figure 46 shows the trigger assembly.
47) Push the trigger forward so the sear clears the receiver and then push from right to left until the assembly clears the receiver.  Be careful to not let the sear spring fly free.
48) Remove the sear spring.
49) Drift the trigger pin out.
50) Separate the trigger and sear.
51) Remove the ejector pin and the ejector will fall out of the receiver.
Note: If all possible use small brass or nylon non-marring tools when driving out small parts so as not to damage parts or the finish on any parts on a highly valuable and collectible firearm. If all you have (like pictured) is a small flat blade stainless steel screw driver please be careful.
52) Rotate the magazine cutoff down and then insert a small screw driver to depress the spindle.  With the spindle depressed slide the cutoff out.
