16. Drift out the trigger cross pin toward the right.
17. Push the sear forward and hold it there while removing the trigger assembly upward. When the trigger is clear, allow the sear to snap over to the rear, partially relieving the tension of its spring. If necessary, drifting out the cross pin will separate the disconnector from the trigger.
18. Drifting out the sear cross pin toward the right will release the sear and its spring for removal upward. Caution: The sear spring is quite powerful. Restrain the sear and ease it out.
19. The magazine release button, located on the right side at the lower rear of the magazine housing, is screw-slotted and is threaded into the catch block on the opposite side. Unscrew the button, take it off toward the right, along with the spring, and remove the catch block
20. The grip handle is retained by a screw angled upward into the lower frame, accessible through the bottom of the handle. Remove the handle downward.
21. Remove the large and small Phillips screws at the rear of the buttstock, and take off the buttplate toward the rear. Slide the buttstock off toward the rear.
22. Unscrew the spring housing from the rear of the frame, and remove it.
23. Turn the upper buttplate screw back into the nylon bushing at the rear of the spring housing, and using the screw and a screwdriver push the bushing inward, then rotate it one quarter turn toward the right (clockwise, rear view). Caution: Grip the rear bushing firmly, and ease it out slowly, as this powerful spring is partially compressed, even when at rest.
24. Remove the rear bushing and recoil spring toward the rear.
25. Move the spring guide and follower to the rear, and rotate these parts until their lugs are aligned to clear the detent depressions at the rear of the tube. Remove the guide and follower toward the rear.
Reassembly Tips:
1. When replacing the firing pin in the bolt, be sure the firing pin is oriented so its retaining recess is toward the top of the bolt, to accept the nose of the retainer.
When replacing the trigger and disconnector assembly, push the small rear spring pin halfway across, and hook the rear loop of the expansion spring onto it. Then, drive the pin into place. Lift the sear and insert the front of the disconnector arm into the vertical slot in the sear. Allow the sear to hold the trigger and disconnector in place while the trigger is positioned for insertion of its cross pin.
When replacing the cocking handle and bolt assembly, the cocking handle must be inserted first, and moved up into its track before insertion of the bolt. Note that the ejection port cover must be open as the bolt is inserted.

The Model 20P is a later and slightly redesigned version of earlier 22 semi-autos that were made in the Philippines by the Squires Bingham company. These are well-made guns, but there are several points in complete takedown that may be problems for the non-professional. These are noted in the instructions. The Models 20C, 2000SC, 2000, and 50S differ only in stock details and accessories.
